Professional Applications & Engineering Value
This M12 set screw with extra fine 1.25mm pitch delivers exceptional engineering value in applications requiring precise axial positioning and vibration resistance. The alloy steel construction with Rockwell C45 hardness provides the necessary strength for permanent fastening in machinery, automotive components, and precision equipment. The headless hex drive design with 6mm drive size allows installation in confined spaces while maintaining high torque capability. The cup tip configuration creates concentrated pressure points that prevent slippage in shaft collars, gears, and pulleys. Meeting DIN 916/ISO 4029 standards, this metric set screw ensures interchangeability and reliability in international engineering projects where fine thread adjustment is critical for alignment and positioning accuracy.
Specification Summary & Compliance
This metric set screw features M12 x 1.25mm extra fine thread with Class 5g6g thread fit tolerance according to ISO metric thread standards. The 12mm length with right-hand thread direction and cup tip design conforms to DIN 916 ISO 4029 manufacturing specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors without hazardous substance restrictions.
