Professional Applications & Engineering Value

These alloy steel set screws deliver exceptional engineering value in applications requiring permanent positioning of components on shafts, axles, and spindles. The M10 metric thread with coarse 1.5mm pitch and Class 5g6g thread fit ensures precise engagement while accommodating minor misalignments. The 90° cone point creates concentrated pressure points that penetrate mating surfaces, solving common vibration-induced loosening problems in rotating assemblies. Manufactured from hardened alloy steel to Rockwell C45 standards, these hex headless set screws maintain dimensional stability under heavy loads, making them ideal for machinery, automotive components, and industrial equipment where reliable positioning is critical. The 5mm hex drive provides sufficient torque transmission without compromising the compact headless design essential for space-constrained applications.

Specification Summary & Compliance

This M10x1.5x12mm set screw features precision metric coarse threads with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and reliable performance. The manufacturing process adheres to DIN 914 and ISO 4027 specifications, guaranteeing consistent quality and interchangeability. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, making these set screws suitable for global industrial applications requiring regulatory adherence. The right-hand thread direction and 12mm length provide standardized installation across compatible components.
