Professional Applications & Engineering Value
This M20 socket head cap screw delivers critical engineering solutions where high tensile strength and precision threading are paramount. The black-oxide alloy steel construction provides essential corrosion protection in manufacturing environments exposed to moisture and chemicals. With its Class 12.9 rating and 170,000 psi tensile strength, this fully threaded fastener maintains structural integrity in heavy machinery, automotive assemblies, and industrial equipment subject to extreme vibrations and dynamic loads. The coarse 2.5mm pitch thread enables rapid installation while the 17mm hex drive ensures secure tool engagement during high-torque applications, reducing assembly time and preventing fastener damage in production lines.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance for precision engagement. The metric coarse threading (M20 x 2.5mm) follows international standards while the 100mm fully threaded design provides consistent fastening performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications worldwide.
