Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M10 socket head cap screw solves critical fastening challenges in heavy machinery, automotive assemblies, and structural frameworks. The Class 12.9 alloy steel core delivers unmatched tensile strength (170,000 PSI) to withstand extreme mechanical loads, while the zinc-plated surface provides essential corrosion protection in humid or chemically aggressive environments. The partially threaded design with 32mm thread length ensures optimal clamp force distribution, preventing joint loosening under vibration. With coarse metric threading (1.5mm pitch) and hex drive compatibility, installation efficiency is maximized in high-volume production settings where reliability and speed are paramount.

Specification Summary & Compliance

This metric socket head cap screw maintains precision Class 5g6g thread fit per ISO standards with 40mm total length and 16mm head diameter. Manufacturing complies with DIN 912/ISO 4762 specifications for dimensional accuracy and mechanical properties. The product fully meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental compliance for global industrial supply chains.
