Professional Applications & Engineering Value

This M4 socket head cap screw delivers critical performance advantages in demanding industrial applications where reliability is paramount. The 18-8 stainless steel composition provides excellent corrosion resistance, making it suitable for machinery, automotive components, and electronic enclosures exposed to moisture or chemicals. The Class 4g6g thread specification ensures precise fitment with mating components, reducing the risk of cross-threading and maintaining clamping force under vibration. The fully threaded design offers consistent engagement depth, while the vented feature prevents pneumatic or hydraulic lock in sealed systems. With its metric coarse thread (0.7mm pitch), this fastener enables quick assembly while maintaining the structural integrity required for high-stress applications.

Specification Summary & Compliance

This precision socket head cap screw features M4 x 0.7mm metric coarse thread with Class 4g6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The 16mm length provides consistent engagement, while the standard hex drive (3mm) guarantees reliable tool interface. Manufactured from 18-8 stainless steel with Rockwell B70 hardness and 70,000 psi tensile strength, this fastener meets rigorous mechanical requirements. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance for industrial fastener applications.
