Advanced Tools for Automated Rivet Nut Installation
A240-BI Automation System
Sherex offers a wide range of advanced automated rivet nut installation systems and hand tools designed to deliver efficient, accurate installations. Our automation solutions are ideal for a variety of industries — automotive, aerospace, industrial equipment — and any application requiring high-volume installations with built-in quality assurance.
These state-of-the-art rivet nut automation systems combine ergonomic design with intelligent integration and robust performance. Systems can be fully automated — utilizing a robotic arm for rivet nut installation — or semi-automated, where an operator manually feeds components into the system.
Sherex Automation hand tools and process monitoring systems support a wide force range and can install Sherex rivet nuts from M3–M16 and unified thread equivalents. They are compatible with round, full hexagonal (full hex), and semi-hexagonal (semi-hex) body style rivet nuts, and rivet nut studs. All Sherex hand tools are assembly-line ready and equipped with process monitoring capabilities to ensure precision installations.

A240-BI - Automated Robotic C-Frame Installation
The Sherex Automation by MDS A240-BI Workstation is a fully automated robotic C-Frame press. It is similar to the A230 system, except the setting head is in a fixed position and the component is moved to the setting position through robotic or other automated handling systems.
The setting unit sits on a frame made of solid aluminum profiles. The frame contains electrical components, the pressure booster as well as the pneumatic control elements and protects them from dirt or damage.
Upwards installation on the A240-BI is measured by direction of final position and final pressure. Downward installation of rivet nuts is measured by displacement measuring systems and pressure.
- Used commonly for lighter weight components and smaller components
- Can be used as a human-operated workstation
- Can be used where the robot performs part handling
- Installations for round body, full hex, semi hex rivet nuts and rivet nut studs
A230-BI Mobile Robotic Tools for C-Frame Installation
The Sherex Automation by MDS A230-BI is an end of arm robotic attachment (setting head) for installing rivet nuts into the application, eliminating the need for manual assembly. The robot positions the setting head to each installation position on the component, and the fastener is then placed into the hole and installed.
- Rivet nuts are bulk loaded into a feed cart, automatically feeding each rivet nut to the setting head for installation
- An OK/NOK (Not OK) signal is generated for each installation to ensure a quality product is produced
- Used in a variety of different industries, including automotive, heavy truck, solar power, and for general industrial applications
- Installations for round body, full hex, semi hex rivet nuts and rivet nut studs
- Rivet nuts can be installed by this machine in any direction the customer desires
A220-BI – Manual C-Frame Installation
The Sherex Automation by MDS A220-BI is a manual C-frame press designed for inserting rivet nuts and rivet nut studs. This semi-automated workstation provides a reliable solution for controlled, efficient assembly.
The setting process is similar to the A230-BI mobile robotic tool — the operator inserts the component, and the setting unit is moved into position.
Key Features
- Patented active tolerance compensation
- Feeding system and controller module positioned outside the danger zone
- Integrated displacement measurement system with active pre-stroke
- Force-displacement process monitoring
- Compatible with round body, full hex, semi-hex rivet nuts and rivet nut studs
A210 -- Process Monitoring Hand Tools
A210 — Process Monitoring Hand Tools
Sherex Automation offers two hydropneumatic spin-pull tools with process monitoring: the FLEX-8 and FLEX-18. These tools install all types of blind rivet nuts and rivet nut studs in sizes M8–M16 and unified thread equivalents.
Each unit is custom-configured based on the application and fastener type. Integrated sensors record force-displacement curves in real time. If the curve falls outside a pre-defined window, the installation is flagged as NOK (Not OK).
The FLEX-8 (35kN) and FLEX-18 (80kN) both feature lightweight handheld tools connected to an external booster box containing the displacement sensor, pressure amplifier, and other key components. Up to four tools can be linked to a single monitoring system. These systems are popular in automotive, heavy truck, and applications where proof of satisfactory rivet nut installations are required.
