Professional Applications & Engineering Value
This M3 x 0.5 mm set screw delivers critical engineering solutions for precision mechanical assemblies requiring secure component positioning. The zinc-plated alloy steel construction provides excellent corrosion protection while maintaining Rockwell C45 hardness for high shear strength. Its 90° cone point creates concentrated pressure points that prevent axial movement in pulleys, gears, and collars – effectively solving vibration-induced loosening in rotating machinery. The coarse thread spacing and Class 5g6g thread fit ensure rapid installation and reliable engagement in both through-holes and blind tapped holes. These headless set screws are particularly valuable in compact motor assemblies, precision instruments, and automation equipment where space optimization and vibration resistance are paramount.
Specification Summary & Compliance
This metric set screw features M3 x 0.5 mm coarse threads with Class 5g6g thread fit tolerance per ISO metric standards. Manufacturing specifications strictly adhere to DIN 914/ISO 4027 dimensional requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
