• Environmentally Responsible Sourcing: RoHS 3 and REACH compliance ensures safety and regulatory adherence for global supply chains.

Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in precision assembly and machinery. The alloy steel composition, hardened to Rockwell C45, delivers exceptional shear and tensile strength, preventing failure in high-stress environments like motor mounts, gear assemblies, and automation equipment. Its headless design and flat tip are ideal for set screw applications requiring a flush finish, securely positioning components on shafts and axles without protruding. The coarse metric thread (0.5mm pitch) ensures rapid installation and robust grip in softer materials or where vibration resistance is paramount. Fully compliant with DIN 913/ISO 4026 standards, these screws provide reliable, repeatable performance for OEMs and maintenance teams in automotive, aerospace, and industrial machinery sectors.
