Professional Applications & Engineering Value

These Class 12.9 socket head cap screws deliver critical engineering solutions where high tensile strength and reliability are paramount. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the Rockwell C37 hardness required for repeated torque applications. The metric coarse thread (M8 x 1.25mm) design ensures rapid assembly in production environments while minimizing thread damage. With 28mm minimum thread length and Class 5g6g thread fit, these fasteners maintain precise tolerances in heavy machinery, automotive systems, and industrial equipment where vibration resistance and load distribution are critical. The partially threaded design offers flexibility for both clamping and precision alignment applications, making them ideal for jigs, fixtures, and structural assemblies requiring both strength and positioning accuracy.

Specification Summary & Compliance

Manufactured to exact DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring precise engagement. The 100mm length with 28mm minimum thread length provides consistent performance across applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage in international markets. The Class 12.9 strength rating and 170,000 psi tensile strength verify mechanical performance exceeds industry requirements for critical fastening applications.
