• Wide industrial compatibility with coarse M3 x 0.5 mm metric threads for quick assembly and disassembly
• Environmental compliance assurance meeting RoHS 3 standards, making it suitable for regulated industries

Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in precision machinery and industrial equipment. The alloy steel construction, hardened to Rockwell C39, provides exceptional resistance to shear and tensile stresses, preventing failure in high-vibration environments like motor assemblies and gearboxes. The ball tip design offers concentrated contact pressure, securely locking components onto shafts without marring surfaces—ideal for adjustable collars and pulleys. With its Class 6g thread fit and coarse pitch, it ensures rapid installation and reliable clamping force, reducing assembly time while maintaining alignment in automation systems and manufacturing tools. This hex headless fastener is a trusted solution for applications demanding repeatable precision and long-term reliability.

Specification Summary & Compliance

This set screw adheres to metric thread standards with M3 x 0.5 mm coarse pitch and Class 6g tolerance for consistent fit. It meets RoHS 3 (2015/863/EU) compliance under exemption 6(a) for lead as an alloying element in steel, ensuring it is suitable for use in electronics and other regulated sectors. Manufactured from alloy steel and heat-treated to Rockwell C39 hardness, it guarantees dimensional stability and performance in industrial fastening applications.
