• Optimized thread engagement with M8 x 1.25mm coarse threads and Class 5g6g fit for faster assembly and vibration resistance
• Versatile partial threading allowing both clamping and alignment functions in a single fastener solution
• Enhanced durability from Rockwell C37 hardness alloy steel construction that withstands repeated use and impact
• Global compliance assurance meeting DIN 912/ISO 4762 standards plus RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

These high-strength socket head cap screws deliver critical performance advantages in demanding applications where reliability is non-negotiable. The blue-dyed zinc-plated alloy steel construction provides both corrosion protection and visual identification benefits in assembly operations. The M8 coarse thread configuration with Class 5g6g thread fit ensures rapid installation while maintaining precise tolerances for machinery, automotive components, and industrial equipment. The partially threaded design offers flexibility for applications requiring both clamping force and smooth shank guidance. With 170,000 psi tensile strength and Rockwell C37 hardness, these fasteners withstand extreme mechanical stresses, making them ideal for heavy-duty fixtures, precision tooling, and structural assemblies where failure is not an option.

Specification Summary & Compliance

This M8 x 1.25mm socket head cap screw features precise Class 5g6g thread tolerances according to metric standards. The fastener complies with DIN 912/ISO 4762 manufacturing specifications for dimensional accuracy and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in various industrial sectors. The 70mm length with 28mm minimum thread length provides consistent engagement depth, while the 13mm head diameter and 8mm head height maintain standard socket tool compatibility across global markets.
