Professional Applications & Engineering Value
Engineered for demanding industrial settings, this M12 socket head cap screw delivers critical reliability in machinery, automotive, and heavy equipment assemblies. The zinc-flake-coated alloy steel construction combats corrosion effectively, addressing common failure points in exposed or humid conditions. With a Class 12.9 strength rating and coarse metric thread, it provides robust clamping force and rapid installation in structural components, reducing downtime. The fully threaded, right-hand design ensures uniform stress distribution and ease of use in tight spaces, making it ideal for high-vibration environments where socket head cap screws must maintain integrity under dynamic loads.
Specification Summary & Compliance
This screw adheres to precise metric thread specifications with a Class 5g6g tolerance for consistent fit. It meets DIN 912 and ISO 4762 dimensional standards, along with ASTM B117 for corrosion testing. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are upheld.
