  3. Optisert Receives 2023 Fastener Innovation Award!

    Leave a Comment

    Sherex Fastening Solutions’ Optisert, the best performing round body rivet nut on the market, was recently awarded as a winner of the 2023 Fastener Innovation Awards by

    The innovative Optisert was chosen as a winner because of its incredible performance against spin-out. Its proprietary combination of an engineered knurled body and underhead wedge design helps it grip into the base material to prevent it from spinning. In softer materials, like aluminum, plastics, and composites, the spin-out performance matches that of a full hex body rivet nut.

    This award “aims to recognize the people and companies to encourage Research & Development in the fastener industry,” as stated in the release by Mike McGuire, president of

    “We are proud that the Fastener Innovation Awards are based on technical advancements compared to what exists in the marketplace today,” McGuire was quoted in the release.

    The Certificate of Recognition and Crystal Marquise Globe given to the award winners

    This is now the second recognition for Optisert, as it was also a finalist for the Route to Fastener Innovation 2023.

    Optisert took over 7 years of research and development to become part of Sherex’s standard part offering. That meant lots of testing and tinkering to make sure Optisert would be ready to perform as a premier round body rivet nut in softer materials.


    Optisert’s underhead wedges and engineered knurls give it superior grip

    “A driving force in the evaluation process is that the fasteners be innovative in assemblies today and that they will become tomorrow’s standard,” the award release said. “Our philosophy is continuous improvement with innovative solutions for customers’ fastening applications.”

    Sherex shares the same philosophy and with more innovations coming soon, more awards should be on the way!

  4. Sherex Fastening Solutions Year in Review 2023!

    Leave a Comment

    Hi all! This year seemed to be the year when the COVID pandemic was clearly in the rearview mirror. We launched the best-performing round body rivet nut, Optisert (which customers love), traveled to see our great customers more than ever, and came up with some great solutions for our customers to solve difficult fastening problems.

    Optisert Buzz Is Growing


    Optisert’s diamond wedges and engineered knurls creates incredible spin-out resistance

    While saying Optisert is the best-performing round body rivet nut may sound like marketing talk, we have the data to back it up. Now, we have the customers too. Many assemblers made the switch to Optisert, and one chose the new round body standard over a potential, and costly, change to a hex body rivet nut too.

    The benefit is simple: Optisert’s spin-out performance in composite, plastics, carbon fiber, aluminum, and other softer materials is as great as a hex body rivet nut. Spin-out resistance is critical in many applications, and round body rivet nuts have had significantly less spin-out resistance than hex body rivet nuts. Now, if OEMs can’t produce a hex hole, they can feel confident that Optisert can deliver the performance they expect from a threaded fastener.

    We’ve seen Optisert in automotive, heavy truck, and general industrial applications with more projects on the way.

    Solutions for Heavy Trucks and Construction and Agriculture Equipment

    We’ve added two new industry pages and a solutions for composite page that highlight some of the most popular and best practice fasteners for the application.

    The Fastener Solutions for Heavy Trucks, Fastener Solutions for Construction and Agriculture Equipment and Fastener Solutions for Composite Materials pages are designed for OEMs and distributors to think about the applications they have and how the joint can be secured better or assembled better. Use the products other assemblers are using in your own to save money and decrease waste.

    While many of these our products are standard rivet nut products in our catalog, others are custom solution fasteners designed specifically for the application. Our engineering team will work directly with the OEM to find a solution that is the best performing, cost effective, and makes it easier on assemblies.

    Sherex President Adam Pratt Presentation at IFE

    Sherex President Adam Pratt had the opportunity to present at IFE and talked about a variety of topics, including how rivet nut fasteners are ideal replacements for weld nuts. The talking points in all of these snippets are great and useful when talking about Sherex products or rivet nut fastening in general.

    Take a look at the videos below:

    Benefits to Using Process Monitoring

    More Innovations to Come!

    Like our Optisert round body rivet nut – Sherex has a few more “game-changers” in the hopper that assemblers will love to get their hands on. As Adam Pratt said in his presentation at IFE, Sherex will always try to innovate and push assemblers to use the best fastener for the application. And with more products to come, that means better fasteners and better applications.

  5. Compression Limiting Rivet Nuts

    Leave a Comment

    In our last blog post, we discussed compression limiters, their usage, and their benefits. However, there is an even simpler solution available: combining a compression limiter with a rivet nut to create a compression limiting rivet nut.

    A compression limiting rivet nut integrates both a rivet nut and a compression limiter into a single piece with a unique part number.

    Example of a Compression Limiting Rivet Nut

    This part offers several advantages:

    1. It is a single component instead of two separate parts. This streamlines assembly time and simplifies the ordering process for purchasers, as they only need to consider one part.
    2. It is cost-effective. A compression limiter and a rivet nut combined would likely cost more than a specially designed compression limiting rivet nut.

    How does it work?:

    With a compression limiting rivet nut, it pretty much acts as a rivet nut with a bigger shoulder or spacer combined on top of the rivet nut. When the compression limiting rivet nut installs, it installs into the base material, but the spacer or compression limiter then sits above it as to not distort the material sitting on top.

    Top half is the compression limiter, bottom half rivet nut!

    Like all compression limiters made and designed by Sherex, they are all unique to the application and the same applies with these compression limiting rivet nuts. They are very popular in automotive applications with pretty much limitless designs: round body, hex body, underhead seals, knurls, ect. Sherex engineering works with the application design engineers to come up with a design that will surpass performance expectations while also being the most cost-effective solution compared to other fastening options.

    So, if considering a compression limiter, a compression limiting rivet nut might be the solution you need!

  6. What are Compression Limiters?

    Leave a Comment

    Compression limiters are typically cylindrical components made of steel, stainless steel, brass, or aluminum that prevent overstressing of usually plastic or composite material and fastener clamp load loss during fastener installation. They can be used integrated with a fastener, such as a rivet nut, to provide metal to metal transfer of forces during the joint assembly.

    This helps to prevent the surrounding material from being deformed or damaged.

    Essentially, the compression limiter can fill a gap for a metal on metal load transfer as to not deform the material. So when the fastener, such as a screw or bolt, is tightened, the compression limiter is compressed between the fastener head and the metal parts being joined for a compact assembly.

    The designs of a compression limiters are limitless. They can very large or very small, have knurls or wedges, or just be a smooth body cylinder like a spacer. What all compression limiters have in common, though, is that they are UNTHREADED. In some scenarios a bolt may pass through the compression limiter, it doesn’t have threads to keep the bolt in place.

    What applications are compression limiters used in?

    Metal compression limiters are commonly used in industries such as automotive, aerospace, construction and agricultural equipment, and in general construction where high strength and reliability are crucial. They are often used in applications where the joint must withstand significant loads or stresses, such as in structural connections or engine components. They are oftentimes used to not distress the base material.

    How they are made?

    Compression limiters are either cold-formed or machined. Sherex engineers design compression limiters for specific applications, so many of these parts are unique to the project they were designed for.

    Sherex makes hundreds of thousands of compression limiters every year out of its Sherex Akron facility in Akron, Ohio. To learn more about compression limiters or if in of a compression limiter for your application, contact us!

  7. Optisert Rivet Nut vs Hex Body Rivet Nut in Automation

    Leave a Comment

    It’s recommended that if manufacturers and assemblers can create a hex hole, using a hex body rivet nut is the best way to attach a joint together.

    But what if you’re using a fastener automation system? Is a hex body rivet nut the best rivet nut to use when installing them automatically through an automation installation system?

    Probably not. Especially now with Optisert available.

    With high volume installations of rivet nuts, automation is a best practice method. It’s faster than human installation, installations are perfect (and if they’re not the system will let you know), and it doesn’t need a human to install the rivet nuts. But when using a hexagonal hole to install hex body rivet nuts using automation, this is where things get tricky.

    Optisert Rivet Nut vs Hex Rivet Nut

    Optisert vs. Hex Body Rivet Nut

    The automation feeder needs to be able to line up the points of the hex body rivet nut with the points of the hex body hole, perfectly. It’s not ideal, but possible through more expensive automation equipment. With a round body rivet nut into a round hole, there’s no need to worry about the points lining up… because, well, there’s no points on a round body rivet nut or a round hole!

    Oh yeah, but what about performance?

    So yes, hex body rivet nuts are recommended. It’s the best rivet nut at resisting spin-out. BUT, Optisert can hold its own. Its performance metrics are greater than a half hex body style rivet nut, and more similar to a full hex body style rivet nut in some base materials (softer materials like plastic, composite, aluminum). Plus, Optiserts are less expensive than full hex body style rivet nuts.

    So when deciding between full hex rivet nuts and round body rivet nuts for automation, rivet nut performance might not be the first criteria. Ease of installation for the automation system to run efficiently will be a high priority. With Optisert’s performance similar to a hex body rivet nut, and it being a round body, Optisert might very well be the best rivet nut option for automation on the market today.

  8. Why We’re Calling Optisert “The Best”

    1 Comment

    It’s a little brash, but Sherex has the data to back it up: we’re calling Optisert the best round body rivet nut based on performance.

    Sherex has been working for over five years on a round body rivet nut that can perform comparably vs. a half hex body rivet nut. This rivet nut can do that.

    We are still going to recommend a full hex body rivet nut if you can make a hex hole – especially in harder material like steel and stainless steel. But if a round hole is the only hole that can be produced, especially in softer materials like plastic, fiberglass and aluminum, Optisert’s performance is impressive.

    “We’ve had over five years of product development to get the performance where we want it,” said Sherex Engineering Manager John Knechtges. “We’ve done similar wedgehead, knurled rivet nuts as specials for projects, but this standard part has unmatched performance. We’re really proud.”

    Let’s look at the numbers:

    Optisert vs. CAL Series and CAL Wedge round body:

    Optisert vs. Half Hex:

    The numbers speak for themselves. Optisert spin-out performance is closer to the performance of a full hex rivet nut than a normal, round body CAL rivet nut, and GREATER than a half hex rivet nut.

    With knurls underneath the flange that bite into the material, resistance to spin out is very extraordinary. Spin-out occurs when the rivet nut spins into the hole it’s installed into. Spin-out would potentially occur in applications that experience heavy vibration, or in applications that experience a lot of strain and force.

    For industries that are continuously looking for lightweighting options, like automotive and heavy truck, Optisert is an ideal option for a threaded insert fastener. Optisert also comes in a closed end option with a seal that comes standard. The seal does not compromise grip, and helps keep dust and water out of the base material.

    What a year!

    It was great getting back to some normalcy. But with getting back to normal and ramping up came with challenges many manufacturers ran into this year: SUPPLY CHAIN. With that said, we feel we navigated supply chain issues better than our competitors and we even made moves that will hopefully mitigate those risks in the future.

    Let’s take a look at some of the highlights from Sherex this year!

    Operators LOVE our Calibration Unit and our Process Monitoring Units

    Hand Tool Calibration Unit

    Sherex’s Hand Tool Calibration Unit

    When we released our Hand Tool Calibration Unit in 2020, we knew this would be a great tool for any installer. And after two years, we keep getting glowing praise. We hate to toot our own horn, but the tool is awesome. There are so many features the tool can provide, like exporting historical data, showing the recommended installation force on Sherex rivet nuts, and even graphing those recommended forces on to calibration unit to make sure the tool is inside of those parameters. By periodically checking the force of any spin-spin or spin-pull tool, you’ll feel confident the tool is operating how you want it, decreasing the guessing game on the pulling force, waste, and rework.

    Some of our automotive tiers have had dozens of our FLEX-5 Process Monitoring Tools installed this year. Sherex Process Monitoring Tools let operators know if the rivet nut installation was perfect, instantly. Sherex sets the tool up to determine if the install was correct based on a variety of parameters: hole size, material, material thickness, rivet nut, rivet nut size, pulling force of the tool, etc. When all those parameters qualify, the system reads it as a good installation. This kind of tool combines quality and efficiency, and lets OEMs know, with data, that installations were perfect or not OK. These tools are perfect for high volume installations like on an assembly line and meets the process monitoring requirement many auto manufacturers require.

    Our customers have nothing but great things to say on both these quality tools – you must try them if you haven’t already!

    Sherex Poland and Sherex UK locations are off and running

    We opened Sherex Poland last year and Sherex UK in 2019 and both locations have been building trust and supplying millions of our quality rivet nuts, threaded inserts, clinch nuts, wedge locking products and tools throughout Europe.

    These locations serve as engineering, sales, customer support and warehousing for Europe, bringing us closer to our European customers and therefore, decreasing the total length of our supply chain. This year, new customers were pleasantly surprised we had stock AND could ship quickly! Great year by both Sherex Poland and Sherex UK.
