Professional Applications & Engineering Value
This M8 hex head screw delivers exceptional engineering value in demanding industrial environments where high tensile strength and corrosion resistance are critical. The Class 10.9 steel construction with Rockwell C32 hardness provides reliable performance in heavy machinery, structural steel connections, and automotive assemblies where vibration and dynamic loads are common challenges. The zinc yellow-chromate plating offers superior protection against corrosion in outdoor or chemically aggressive settings, while the coarse thread pitch ensures quick installation and reduced cross-threading risks. The partially threaded design concentrates strength where needed most, making it ideal for applications requiring precise clamping force distribution across multiple material thicknesses.
Specification Summary & Compliance
This metric fastener features M8 x 1.25mm coarse threading with Class 6h thread tolerance and 22mm minimum thread length. Manufactured to ISO 4014/DIN 931 specifications, the screw maintains precise dimensional accuracy throughout its 90mm length. The external hex drive (13mm across flats, 5.3mm height) ensures compatibility with standard installation tools. This industrial-grade hex head screw complies with international quality standards and meets RoHS and REACH environmental requirements for global industrial applications.
