Professional Applications & Engineering Value
This M12 hex head screw delivers exceptional engineering value through its Class 10.9 high-strength construction and black-phosphate surface treatment. The combination of 150,000 psi tensile strength and Rockwell C32 hardness ensures reliable performance in demanding applications including heavy machinery, structural assemblies, and industrial equipment. The partially threaded design with coarse metric thread (1.75mm pitch) provides superior resistance to vibration loosening while the integrated flange eliminates the need for separate washers, streamlining installation. The black-phosphate coating offers excellent corrosion protection, making these metric screws ideal for outdoor equipment, automotive components, and manufacturing facilities where environmental factors challenge fastener integrity.
Specification Summary & Compliance
This M12 x 1.75mm hex head screw features precise Class 6g thread fit tolerance with 30mm minimum thread length and 70mm overall length. Manufactured to ASME B18.2.3.9M specifications with external hex drive and right-hand thread direction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
