Professional Applications & Engineering Value
This M20x2.5 Class 8.8 socket head cap screw delivers exceptional engineering value through its zinc-plated alloy steel composition and low-profile socket head design. The combination of 110,000 psi tensile strength and Rockwell C20 hardness addresses common industrial challenges including joint relaxation under dynamic loads and corrosion-induced failure. The partially threaded configuration with 46mm thread length provides optimal stress distribution while minimizing cross-threading during assembly. Particularly suited for heavy machinery, automotive assemblies, and industrial equipment requiring DIN 6912 compliance, this metric socket screw offers reliable performance where space constraints and high clamping forces are critical design considerations.
Specification Summary & Compliance
Manufactured to DIN 6912 specifications with Class 6g thread fit tolerance ensuring precise dimensional accuracy. The M20 coarse thread (2.5mm pitch) follows standard metric threading conventions while the 17mm hex drive with pilot recess maintains secure tool engagement. This socket head cap screw demonstrates full compliance with RoHS 3 (2015/863/EU) environmental regulations, making it suitable for global industrial applications requiring restricted substance control. The 90mm length with 46mm minimum thread length provides consistent performance across demanding assembly requirements.
