Thread-rolling nut: the TRIMNUT®

A metric nut and a tool in one! With the innovative thread-rolling nut, damaged threads can be repaired easily and professionally. Simple screw connection of the TRIMNUT® nut leads to thread repair and removes rust and dirt. The applications of TRIMNUT® nuts are diverse, as they can be used in a wide variety of industries. In any case, this innovative technology saves you time and money during assembly and disassembly!

The thread-rolling nut can be used in particular in the following industries:

  • Screw connection of metal sheets
  • Alloy systems
  • Automotive industry
  • Occupational safety technology
  • Environmental protection technology
  • Air conditioning technology
  • Aerospace

Repair solutions for damaged threads

With the TRIMNUT® nut, you can make threads reusable despite rust, heavy soiling and impact marks. The thread-rolling nut removes rust and toughest dirt from unusable threads. There is no rubbing of the nut during the assembly of damaged threads. Its functional principle works during screwing and unscrewing and thus ensures safe installation without destroying the connection.

Joining without post-processing

There is no need for post-machining when joining the thread-rolling nut. By applying a metric standard thread to a matching bolt geometry, a direct screw connection is made possible. This can save a complete step in your working routine! The screw connection is secured by a controlled self-locking and offers a higher strength than machined threads, leading to unrestricted power transmission and torque transmission. Damages during the creation of the thread are also avoided since it is comes only into effect during the assembly of the component.

Safe screw connection process

As it is a reliable screw connection, there are no following, additional work steps necessary. Even process-related residues in the thread are removed, such as welding spatter or coating residues. The components no longer have to be extracted from the production line and can be used without restriction. In the screw connection process, there is no “rubbing” of the nut. In addition, the coating remains in the range of the nominal layer thickness.
