Professional Applications & Engineering Value

This M30 socket head cap screw delivers critical engineering solutions where standard fasteners fail. The Black-Oxide alloy steel construction provides superior corrosion resistance for machinery operating in humid or chemically aggressive environments, while the Class 12.9 strength rating ensures reliable performance in heavy equipment, industrial presses, and structural assemblies. The partially threaded design combines the benefits of precise component alignment with high clamping force distribution. With its 22mm hex drive and standardized DIN 912/ISO 4762 dimensions, this fastener enables efficient installation in confined spaces common in automotive jigs, manufacturing fixtures, and precision engineering applications where vibration resistance and repeated disassembly are routine requirements.

Specification Summary & Compliance

Manufactured to precise Class 5g6g thread fit tolerances with M30x3.5mm coarse thread specifications. Fully compliant with DIN 912/ISO 4762 dimensional standards for socket head cap screws. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The partially threaded configuration provides 72mm of threaded length on the 110mm overall body, engineered for optimal performance in industrial applications requiring both precise alignment and high clamping force capabilities.
