Professional Applications & Engineering Value

These M6 socket head cap screws with black-oxide alloy steel construction address critical engineering challenges in demanding environments. The coarse 1mm thread pitch enables rapid assembly while maintaining secure fastening, particularly valuable in high-vibration machinery and automotive applications. The serrated locking flange provides permanent anti-rotation security without compromising disassembly capability. With Rockwell C39 hardness and 140,000 psi tensile strength, these metric hex socket screws withstand extreme mechanical stresses in precision equipment, manufacturing fixtures, and heavy machinery where reliability is paramount. The partial threading design allows for precise clamp load distribution, making them ideal for applications requiring exact positioning and repeated adjustments.

Specification Summary & Compliance

This flange screw features M6 x 1mm coarse thread metric configuration with Class 5g6g thread fit tolerance per ISO standards, ensuring precise dimensional accuracy. The 30mm length with 24mm minimum thread length provides optimal engagement depth. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safe use across global industrial markets. The 5mm hex drive and standard socket head profile maintain compatibility with industry-standard installation tools.
