Professional Applications & Engineering Value
This M6 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and zinc plating surface treatment. The combination of 110,000 psi tensile strength and Rockwell C21 hardness addresses critical failure points in heavy machinery, automotive assemblies, and structural frameworks where vibration and dynamic loads compromise fastener integrity. The fully threaded design with coarse 1 mm pitch ensures maximum grip length and rapid installation in steel-to-steel applications, while the external hex drive provides superior torque transmission without cam-out. Meeting ISO 4017 and DIN 933 specifications, these metric hex screws offer reliable interchangeability for maintenance and production lines requiring standardized industrial fasteners.
Specification Summary & Compliance
Manufactured to ISO 4017, DIN 933, and SAE J1199 standards with Class 6h thread fit tolerance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features M6 x 1 mm coarse thread with 40 mm length and right-hand thread direction.
