Professional Applications & Engineering Value

These Class 10.9 hex button head screws deliver critical engineering solutions where high tensile strength and space optimization are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, automotive assemblies, and industrial equipment exposed to harsh operating conditions. The M5 coarse thread design (0.8mm pitch) ensures rapid installation and superior vibration resistance in dynamic applications. With fully threaded engagement along the 25mm length, these metric fasteners distribute clamping forces evenly, preventing joint failure in structural components. The rounded button head profile with 3mm hex drive facilitates both aesthetic integration and tool access in confined spaces, making them ideal for precision equipment, manufacturing fixtures, and heavy-duty assemblies requiring reliable fastening solutions.

Specification Summary & Compliance

This metric hex button head screw features precise M5 x 0.8mm coarse threading with Class 6g thread fit tolerance according to ISO standards. Manufacturing complies with ISO 7380 specifications for dimensional accuracy and mechanical properties. The fastener meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations for chemical safety. With Class 10.9 strength rating and Rockwell C32 hardness, these screws maintain consistent performance across industrial applications while adhering to international quality and environmental standards.
