Professional Applications & Engineering Value

This M3 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The alloy steel material, hardened to Rockwell B75, provides excellent resistance to shear forces and wear, making it ideal for pivots, guides, and rotating mechanisms in machinery, automation, and electronics. The headless, slotted design and 4mm shoulder diameter with precise fit prevent axial movement and maintain concentricity, reducing maintenance needs. Its right-hand coarse thread (M3 x 0.5mm) ensures robust holding power in metals and plastics, streamlining production while meeting DIN 927 specifications for reliable performance in industrial settings.

Specification Summary & Compliance

This shoulder screw features a Class 6g thread fit and precise shoulder dimensions (diameter: 4 mm, tolerance -0.03mm to 0mm; length: 8 mm, tolerance -0.58mm to 0mm) for high accuracy. It conforms to DIN 927 standards and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence for global industrial use.
