Professional Applications & Engineering Value
These Class 12.9 socket head cap screws deliver critical performance in demanding applications where failure is not an option. The black-oxide alloy steel construction provides essential corrosion protection for machinery exposed to moisture, chemicals, or outdoor elements, while the M27 x 3mm coarse thread design ensures rapid installation in heavy equipment assembly. Engineers specify these metric socket screws for structural connections in industrial machinery, automotive jigs, and manufacturing equipment where the 170,000 psi tensile strength prevents joint failure under extreme vibration and dynamic loads. The partially threaded design offers precise clamping control in applications requiring both secured fastening and alignment functionality.
Specification Summary & Compliance
Manufactured to DIN 912 / ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring precise mating with standard nuts and threaded holes. The 180mm length with 66mm minimum thread length provides consistent engagement depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and material traceability for global industrial applications.
