Professional Applications & Engineering Value
Engineered for industrial fastening challenges, this M12 hex head screw combines Class 10.9 high-strength steel with a blue-dyed zinc-plated finish to combat corrosion and provide clear part recognition. The coarse metric thread (1.75mm pitch) ensures rapid assembly and secure holding in vibrating machinery, construction frameworks, and automotive components. Its partially threaded shank design concentrates clamping force, preventing joint slippage and material deformation. With ISO 4014/DIN 931 compliance, it meets rigorous international standards, offering reliability in heavy-duty engineering applications where durability and precision are paramount.
Specification Summary & Compliance
This screw adheres to ISO 4014/DIN 931 specifications, with Class 6g thread fit ensuring precise dimensional accuracy. It is manufactured from steel with a metric M12 x 1.75mm coarse thread, right-hand direction, and 50mm length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming environmental safety and regulatory adherence for global industrial use.
