Flange Head IP4-1 Two-Way Security Screw M8 Thread – 40mm

Product Overview:
The Flange Head IP4-1 Two-Way Security Screw M8 Thread – 40mm provides a controlled, high-security fixing for commercial mesh fencing installations. Its specialist IP4-1 drive is designed to be installed and removed only with the corresponding tool supplied exclusively by Integrity, reducing the risk of interference using commonly available Pin Torx, Pin Hex or standard drive bits. The flange head distributes pressure across the fixing point, supporting secure attachment of compatible mesh clips, clamp bars and fencing components.

Manufactured from hardened steel, the screw offers significantly improved resistance to drilling, sawing and other attempted attacks. A corrosion-resistant surface finish provides up to 1,000 hours of protection, making it suitable for exposed commercial, industrial and infrastructure environments. Versions may be manufactured with under-head anti-vibration serrations where required. The IP4-1 design is EU registered under number 22462363-01. To protect the security of the drive system, availability is restricted to approved OEM customers, so eligibility should be confirmed before ordering.
