Professional Applications & Engineering Value
This M10 hex head screw delivers critical engineering solutions where high tensile strength and durability are paramount. The Class 10.9 steel construction combined with Rockwell C32 hardness resists deformation under extreme loads, making it ideal for structural frameworks, heavy machinery, and automotive assemblies. The partially threaded 230mm length allows the unthreaded shank to bear shear forces while the metric coarse thread (M10x1.5) ensures rapid installation in steel, aluminum, or composite materials. Its external hex drive and right-hand threading provide familiar, reliable fastening for maintenance and production lines, reducing downtime and improving operational efficiency in industrial settings.
Specification Summary & Compliance
Manufactured to DIN 931 standards with Class 6g thread fit tolerance for consistent dimensional accuracy. The screw features M10x1.5 coarse threads and partial threading over a 45mm minimum threaded length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety adherence for global industrial supply chains.
