Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M3 flat head screw addresses critical needs for security and durability. The 18-8 Stainless Steel material, enhanced by a passivated finish, combats corrosion in moisture-prone settings like outdoor enclosures or chemical processing equipment. Its tamper-resistant hex drive (3/32") prevents tampering in public infrastructure, electronics, and machinery, reducing maintenance and vandalism risks. The metric coarse thread (M3 x 0.5 mm) ensures quick, reliable fastening with a Class 6g fit, minimizing cross-threading and providing excellent vibration resistance in assemblies. Fully threaded for consistent clamping force, it is a top choice for security screws in panels, fixtures, and devices where long-term integrity is non-negotiable.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including a Class 6g thread fit per ISO metric specifications for consistent accuracy. It is manufactured in compliance with ASTM F879M for mechanical properties and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are upheld. The design incorporates a 90° countersink angle and fully threaded M3 x 0.5 mm coarse pitch, supporting reliable performance in regulated industrial fastening applications.
