Professional Applications & Engineering Value

This M12 metric socket head cap screw delivers critical performance advantages in demanding engineering scenarios. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the 140,000 psi tensile strength required for high-stress assemblies. The ultra-low socket head profile solves clearance issues in compact machinery designs, while the Class 5g6g thread fit ensures precise engagement in automated production environments. Particularly valuable for industrial equipment, machinery frames, and precision instruments, this fully threaded fastener distributes clamping forces evenly across the entire 14mm length, preventing joint loosening under dynamic loads. The coarse 1.75mm pitch thread facilitates rapid installation in production lines while maintaining vibration resistance.

Specification Summary & Compliance

This socket head cap screw features M12 x 1.75mm metric coarse threads with Class 5g6g precision tolerance and length tolerance of -0.127mm to 0.127mm. Manufactured from alloy steel with black-oxide surface treatment, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The hex drive system utilizes a standard 6mm drive size with an 18mm head diameter and 4mm head height ultra-low profile design.
