Product Overview

The CM ultra-thin nylon-patch anti-loosening screw uses a greatly reduced head thickness to fit extreme assembly spaces; the threaded section is pre-coated with Nylok-type nylon locking adhesive that yields rebound torque resistance under physical compression. It tolerates repeated disassembly and suits precision equipment where space is tight and on-site adhesive application is impossible.

Technical Features

  • Ultra-low head significantly reduces assembly height
  • Pre-applied nylon patch resists loosening via rebound torque, reusable
  • No on-site adhesive application needed, so the assembly process is simplified.
  • Precision cold heading ensures consistent head thickness and thread form.
  • Fits tight spaces and supports automated driving
