Product Overview

The TORX® anti-loosening screw is precisely cold-headed from premium alloy steel and carries a pre-applied nylon locking patch on the thread; the rebound friction created under compression prevents loosening. The nylon patch does not cure or contaminate the thread and supports repeated assembly, making it especially suitable for fastening points on automated lines that require frequent maintenance.

Technical Features

  • Pre-applied nylon locking patch remains effective through repeated assembly
  • Torx drive: high torque transmission and strong resistance to recess wear
  • Precision cold heading plus thread rolling give full, consistent threads.
  • No on-site adhesive application needed, simplifying the assembly process.
  • Fits pick-up and driving on automated production lines
