Professional Applications & Engineering Value
This M3 set screw delivers exceptional engineering value in applications requiring precise component positioning and secure fastening. The zinc-plated alloy steel construction provides reliable corrosion protection for machinery, automotive assemblies, and electronic enclosures operating in harsh conditions. Its headless design and cone point create optimal clamping force for securing pulleys, gears, and collars on shafts without protruding hardware. The Class 5g6g thread fit ensures consistent engagement with mating components, reducing assembly time and preventing loosening under vibration. With right-hand coarse threading and 1.5 mm hex drive, this metric set screw offers quick installation and removal for maintenance operations while maintaining positional accuracy in precision equipment.
Specification Summary & Compliance
This set screw features M3 x 0.5 mm coarse pitch metric threads with Class 5g6g tolerance per ISO standards, ensuring dimensional accuracy and proper thread engagement. Manufactured to DIN 914/ISO 4027 specifications with a 120° cone point angle and 3 mm length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use across industrial applications.
