Hexalobular Socket Head P85 Anti-Loosening Screw

Product Description Hexalobular Socket Head P85 Anti-Loosening Screws are engineered from high-strength alloy steel with a professional-grade P85 chemical adhesive pre-applied to the threads. This coating triggers a chemical reaction upon i...

Product Overview

The TORX cylindrical-head P85 anti-loosening screw has a P85 locking adhesive pre-applied to the thread end; once installed, the adhesive layer reacts chemically to form a strong lock — a semi-permanent type of anti-loosening. With precision cold heading and thread rolling, dimensional consistency is good; suited to critical points that are not frequently disassembled and require absolutely reliable connections.

Technical Features

  • P85 pre-applied chemical locking for high anti-loosening strength
  • Torx drive: high torque transmission, resists recess stripping
  • Cold heading plus precision thread rolling, thread accuracy 6g
  • No contamination of the workplace and no on-site adhesive application step
  • Adhesive quantity and position adjustable to drawing
