Professional Applications & Engineering Value
These Class 12.9 socket head cap screws deliver critical performance where standard fasteners fail. The blue-dyed zinc-plated alloy steel construction provides superior corrosion protection for machinery, automotive components, and industrial equipment exposed to harsh conditions. The partially threaded design with M5 coarse pitch (0.8mm) enables rapid installation while minimizing thread damage risk. With 170,000 psi tensile strength and Rockwell C37 hardness, these metric socket screws maintain clamp force under extreme vibration and dynamic loads, preventing joint failure in precision assemblies. The 4mm hex drive ensures positive engagement with standard tools, reducing installation time and improving workplace safety.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance for precision mating. Features M5×0.8mm coarse thread with 22mm minimum thread length on a 30mm overall length partially threaded shank. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global industrial use.
