Did you know Sherex Fastening Solutions is a Made in America Fastener Company?
Our manufacturing plant in Akron, Ohio makes millions of American made rivet nuts, compression limiters, and inserts for composites every year. Our parts out of Sherex Akron belong in some of the hottest vehicles on the road today, dozens of commercial and military aircraft, general industrial applications, and department of defense products. In fact, our Made in the USA rivet nuts were relied upon when companies pivoted to make products that helped mitigate the spread of the coronavirus, like hand sanitizer and ventilator stands, along with other critical applications for hospitals.
Some of our most popular rivet nut lines are produced out of Sherex Akron, including our CAT and CFT Series, NAS Series, and custom rivet nuts and fasteners.
The CAT style rivet nuts has a low profile flange and can fit into a variety of different material thickness and material. This rivet nut could be a one fit solution if the material you’re looking to fasten has different thickness.
CAT Series Rivet Nuts
All NAS style rivet nuts are also made from our Sherex Akron location. The United States Department of Defense relies on Sherex NAS/MS rivet nuts for a variety of applications.
Our inserts for composite product line is used for structural attachments in plastic applications and are used extensively in the automotive and heavy truck industries as customer drive light weighting initiatives by switching to composite material for their components. In addition, Sherex adds compression limiters to these applications to ensure the mating component is not damaged due to the compressive force of the fastened joint.

Also, most custom rivet nuts are made out of Sherex Akron. With our staff of engineers and manufacturing facility, we’re able to see custom, American made rivet nuts from the design and manufacturing process all the way through quality control.
More upgrades are being made to the facility planned in 2020 to help increase capacity as demand as our Made in America rivet nut products continues to grow. More to come from Sherex Akron!

For real and meaningful sales growth to take place, collaboration, cooperation and trust between the supplier and the distributor is extremely important.
This is why line walks and joint sales visits with supply chain partners at the end user are so vital that they are included in distributor rebate and purchase agreements. This allows both the distributor and supplier to get a better understanding of the project, processes, and to solve problems the end users are seeking help for.
Unfortunately, this doesn’t happen as often as it should. Distributors will often go to their supplier for a solution without providing all of the necessary detail to find the best solution. If suppliers don’t know the end product, that typically means the solution they provide is based on the limited information that has been provided to them.
Understanding that there is confidential information, it is quite common for us to execute non-disclosure agreements to work towards an improved solution that benefits all parties involved.
When working with a distributor at an OEM during a line walk, I witnessed a cumbersome assembly for a rivet nut, with the installer reaching for a machined washer to put under the head of the rivet nut prior to the installation. The washer served to raise the head of the rivet nut up just enough that the gasket which was applied to this outdoor housing would not be crushed during final assembly.
Because of a line walk, over 600,000 of this custom rivet nut have been used to help the end user save time and money.
Looking for a better solutions and explaining the details to the Sherex team, they were able to manufacture a taller profile head that acted as a spacer in the application thereby eliminating the extra machined washer. This saved cost, the need to manage another part number, increased throughput on that assembly line, and reduced worker fatigue. This resulted in over seven years of sales with over over 600,000 parts sold.
Real sales growth occurs for both parties when the supplier and distributor work together to improve an assembly method or fastener joint resulting in the lowest total installed cost and improved performance of the end product. Both the supplier and distributor gains the respect of the end user, more profit, and more opportunities for additional projects. This improves and solidifies the supply channel while elevating sales experience above the “commodity mentality.” Win-Win!

In an earlier post we talked about how corrosion should be considered when choosing the type of rivet nut to use in your next project, and what types of sprays can help deter or limit the pace of red rust and white rust from occurring.
Now water will certainly speed up the corrosion process, but that shouldn’t eliminate the use of rivet nuts in wet conditions, or conditions where a rivet nut will spend some of its life submerged in water or fluid.
Our partner Tubtara® has a few different watertight and fluid proof rivet nuts that are designed with seals underneath the flange to keep water and fluids from leaking through the rivet nut. Tubtara’s Watertight HX series feature a O-ring seal mounted underneath the flange, and provides protection against moisture, oil, and dirt under high pressures. Despite the O-ring, it will deliver a metal to metal contact after installation.
Tubtara Watertight HX Rivet Nut. Notice the O-ring seal underneath the flange.
The Watertight (H)DPX Series is a rivet nut that has an applied sealant underneath the head. This non-reactive seal is resistant to many auto oils, antifreeze and other kinds of fluids with a higher viscosity. The seal in the (H)DPX Series can come in a variety of different seal material including NBR, Viton, silicone, epoxy based, acrylate and polyurethane resin.
Non-reactive seal is great for use in high viscosity fluids
Any application where you wouldn’t want water or fluid to leak underneath or through the rivet nut should require a watertight rivet nut. Without using one of the seals, whether it’s an O-ring or sealant, it may not be completely watertight – especially as corrosion begins to develop.

There’s always peace of mind knowing that a correctly installed rivet nut is the end of your concerns.
However, there is more to a properly installed rivet nut to ensure its success.
Your rivet nut will be exposed to the outside world of air and moisture, or it may reside in an environment where the piece will be subject to many bumps and scratches throughout its lifetime. While correctly installing the rivet nut is vitally important to its success as a fastener, there’s one more consideration you have to combat when it comes to rivet nut installation — corrosion.
Corrosion protection for rivet nuts is vitally important when it comes to ensuring the rivet nut will be successful, and there are many ways to combat corrosion.
First, what is corrosion? Corrosion is a surface oxidation process that appears, mainly, in two forms: white rust and red rust.
White Rust a white powder composed of zinc oxide, which eventually coats portions of a surface containing zinc such as the protective layer of zinc-based plating that coats many rivet nuts.
This corrosion does not directly harm the structural integrity of a piece, but makes the piece more vulnerable to a more compromising form of corrosion — red rust, referred to by many as simply “rust.”
Red rust is an iron oxide that physically eats away at the base iron that composes your piece.
So how do you ensure optimal corrosion protection?
Look for rivet nut offerings that are stress-tested with a “salt-spray” test, which subjects rivet nuts to heavy abrasion until rust appears. Rivet nuts coated in a zinc plate with trivalent chromate, which must, at minimum, withstand 96 hours in a salt-spray test before white rust appears with red rust not appearing for another 240 hours. Zinc plate with trivalent chromate comes in clear, yellow, or black options.
For higher corrosion protection, zinc-nickel platings can achieve white-rust times of up to 144 hours minimum, as well as red-rust times of up to 1,200 hours.
If you have rivet nuts that only come in a trivalent plating, a strip and re-plate operation is possible to obtain the plating that best suits you.
The very best option when it comes to corrosion resistance is stainless steel. Stainless steel, though, can be difficult to install so make sure you have the proper tooling to ensure your stainless steel rivet nuts can be installed properly.
If you have any questions regarding which plating or material solution fits your application best please contact us! We are more than happy to give you the information necessary to make an informed decision.
