Professional Applications & Engineering Value
This M3 set screw is engineered to solve critical challenges in precision assembly and machinery. The alloy steel material, hardened to Rockwell C45, provides the necessary strength to resist shear forces and loosening under dynamic loads. Its headless design and 90° cone point are ideal for set-and-forget applications, such as securing collars, gears, and pulleys onto shafts, where a flush finish is required. The coarse metric thread (0.5mm pitch) and Class 5g6g thread fit ensure quick installation and reliable performance in industrial equipment, automotive components, and electronic enclosures, minimizing maintenance and downtime. This hex drive set screw delivers consistent, high-clamping force for long-term operational integrity.
Specification Summary & Compliance
This set screw features an M3 x 0.5mm coarse pitch with a Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional tolerances. It is manufactured in compliance with DIN 914 (ISO 4027) for consistent quality and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to environmental and safety regulations for global use.
