Professional Applications & Engineering Value
This M6 hex head screw delivers critical reliability in heavy-duty industrial applications where joint integrity is paramount. The Class 8.8 steel construction and zinc plating combat both mechanical stress and environmental corrosion, preventing premature failure in machinery, structural frames, and equipment assemblies. Its partially threaded design with coarse metric threading provides superior resistance to loosening under vibration while enabling precise clamping force distribution. Engineers specify these externally hex-driven fasteners for their predictable performance across automotive, construction, and manufacturing sectors where ASME B18.2.3.1M, ISO 4014, and DIN 931 compliance ensures interchangeability and quality consistency.
Specification Summary & Compliance
Manufactured to Class 6h thread tolerance with M6x1 mm coarse thread configuration and 18 mm minimum threaded length. Full compliance with ASME B18.2.3.1M, ISO 4014, and DIN 931 specifications ensures dimensional precision. Environmental conformity verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance declarations.
