• Optimized thread engagement with M12 coarse thread (1.75mm pitch) and Class 5g6g fit for quick installation and vibration resistance
• Enhanced durability from Rockwell C37 hardness, maintaining structural integrity under repeated stress cycles
• Versatile partial threading (36mm min thread length) allowing both threaded and unthreaded section functionality
• Global compliance assurance meeting DIN 912/ISO 4762 standards and environmental regulations (RoHS 3 & REACH)

Professional Applications & Engineering Value

These Class 12.9 socket head cap screws deliver critical performance where high-strength fastening is non-negotiable. The blue-dyed zinc-plated alloy steel construction provides both corrosion protection and visual identification in complex assemblies. With 170,000 psi tensile strength and Rockwell C37 hardness, they withstand extreme vibrational loads and shock impacts in heavy machinery, automotive systems, and industrial equipment. The M12 coarse thread (1.75mm pitch) ensures rapid installation while maintaining vibration resistance, and the 10mm hex socket drive permits high-torque application in confined spaces. These metric socket head cap screws solve engineering challenges requiring reliable fastening in high-stress environments where failure is not an option.

Specification Summary & Compliance

Manufactured to DIN 912 / ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring precise engagement. The M12 x 1.75mm coarse thread provides optimal performance in most industrial applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across regulated industries. The 120mm length with 36mm minimum thread length offers versatile fastening solutions for various material thicknesses.
