Professional Applications & Engineering Value

This M3 set screw delivers exceptional engineering value in demanding industrial applications where reliable positioning and secure locking are critical. The alloy steel construction with Rockwell C45 hardness provides excellent resistance to vibration loosening and mechanical stress, making it ideal for precision machinery, automotive components, and manufacturing equipment. The headless design with hex drive allows for flush mounting in confined spaces while maintaining easy serviceability. The 90° cone point creates concentrated pressure for superior grip on shafts, collars, and gears, preventing slippage under high torque conditions. Manufactured to DIN 914 and ISO 4027 standards with metric coarse threading, this set screw ensures compatibility with international component specifications.

Specification Summary & Compliance

This metric set screw features M3 x 0.5 mm coarse right-hand threads with Class 5g6g thread fit tolerance per ISO standards. The 25 mm length with cone point tip and 90° angle conforms to DIN 914 ISO 4027 manufacturing specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
