Professional Applications & Engineering Value
This M12 hex head screw delivers critical engineering value through its Class 10.9 steel construction and fully threaded metric design. The combination of 150,000 psi tensile strength and Rockwell C32 hardness addresses common industrial challenges including vibration-induced loosening, heavy load requirements, and environmental exposure. The coarse thread pitch of 1.75mm provides superior performance in soft materials and castings where fine threads might strip, while the external hex drive accommodates high torque applications without cam-out. Engineered to ISO 4017/DIN 933 standards, these fully threaded bolts ensure consistent quality across manufacturing, construction, and machinery assembly applications where reliability cannot be compromised.
Specification Summary & Compliance
This fastener maintains Class 6g thread fit tolerance per metric standards with M12x1.75mm coarse threads and 25mm length. Manufacturing specifications conform to ISO 4017 and DIN 933 standards for dimensional accuracy and mechanical properties. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in global industrial markets.
