Professional Applications & Engineering Value

These M6 socket head cap screws deliver exceptional engineering value in demanding applications where space constraints and corrosion resistance are critical. The zinc-plated alloy steel construction provides reliable protection against oxidation and chemical exposure in manufacturing equipment, automotive assemblies, and machinery frames. The low-profile socket head design enables flush mounting in tight clearance applications while the 4 mm hex drive accommodates standard tools for efficient installation. With Class 8.8 strength rating and 110,000 psi tensile strength, these metric fasteners maintain joint integrity under dynamic loads and vibration, making them ideal for critical connections in industrial machinery, automation systems, and structural frameworks where failure is not an option.

Specification Summary & Compliance

This socket head cap screw features M6 x 1 mm coarse thread with Class 6g thread fit tolerance ensuring precise engagement in metric applications. The fastener meets DIN 7984 specifications for dimensional accuracy and manufacturing consistency. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety standards. The partially threaded design provides 18 mm of thread length on a 25 mm overall length, optimized for applications requiring specific clamping zones while maintaining Rockwell C20 hardness for durability.
