Professional Applications & Engineering Value

This M12 set screw delivers exceptional engineering value through its alloy steel composition and headless design, specifically engineered to address common industrial fastening challenges. The metric coarse thread with 1.75mm pitch provides superior resistance to vibrational loosening in machinery, automotive, and manufacturing equipment where dynamic forces are prevalent. The hex drive style allows for high-torque installation in confined spaces where traditional headed fasteners cannot be accommodated. With Rockwell C45 hardness, this set screw maintains its structural integrity under repeated stress cycles, preventing deformation that compromises clamping force. The flat tip configuration ensures maximum surface contact for secure positioning of gears, pulleys, and collars without creating stress concentration points that could lead to component failure.

Specification Summary & Compliance

This precision fastener features M12 x 1.75mm coarse threading with Class 5g6g thread fit according to ISO metric standards, ensuring dimensional accuracy for consistent performance. The 100mm length provides optimal engagement for various industrial applications. Manufacturing complies with DIN 913 and ISO 4026 specifications for dimensional and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for global market acceptance.
