Professional Applications & Engineering Value
This M8 Class 10.9 black-oxide alloy steel screw delivers critical engineering solutions for industrial applications requiring high tensile strength and corrosion protection. The fully threaded metric coarse pitch design (M8 x 1.25mm) ensures maximum thread engagement in thick materials, while the 5mm hex drive provides superior torque transmission without cam-out. The rounded button head profile offers a streamlined finish that minimizes protrusion in machinery, automotive assemblies, and structural frameworks. Engineered with Rockwell C32 hardness, this fastener maintains integrity under vibration and dynamic loads, making it ideal for heavy equipment, manufacturing fixtures, and construction applications where reliability is paramount.
Specification Summary & Compliance
This metric screw features precise Class 6g thread fit tolerance with M8 x 1.25mm coarse pitch right-hand threading. Manufacturing complies with ISO 7380 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) environmental standards, ensuring regulatory acceptance for international industrial applications.
