Professional Applications & Engineering Value
These M8 metric hex screws with Class 10.9 strength rating and black-oxide alloy steel construction address critical engineering challenges in industrial settings. The combination of 140,000 psi tensile strength and Rockwell C32 hardness ensures reliable performance in heavy machinery, automotive assemblies, and structural frameworks where vibration resistance and load-bearing capacity are paramount. The fully threaded coarse pitch design (M8 x 1.25 mm) enables rapid installation while maintaining secure fastening, significantly reducing assembly time in production lines. The black-oxide surface treatment provides essential corrosion protection for equipment operating in humid or chemically aggressive environments, while the rounded button head profile offers a low-profile finish that minimizes snagging hazards in moving machinery components.
Specification Summary & Compliance
Manufactured to precise ISO 7380 specifications with Class 6g thread fit tolerance ensuring dimensional accuracy and interchangeability. The M8 x 1.25 mm coarse thread configuration provides optimal engagement in various materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming adherence to international substance restriction standards for global manufacturing requirements.
