Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. Made from alloy steel with a zinc-plated finish, it resists corrosion and wear in demanding environments like machinery, automotive systems, and electronic enclosures. The low-profile socket head allows for compact designs, while the right-hand metric thread and coarse pitch enable quick, secure fastening. The shoulder provides a precise bearing surface, reducing misalignment and shear stress, which is vital for maintaining industrial equipment accuracy and longevity. By integrating tight tolerances and robust materials, this screw minimizes assembly errors and enhances operational reliability.
Specification Summary & Compliance
This shoulder screw adheres to DIN 923 specifications, with a Class 6g thread fit ensuring dimensional accuracy. Key tolerances include shoulder diameter (-0.03 mm to 0 mm) and shoulder length (0.07 mm to 0.15 mm) for consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from restricted substances, suitable for global industrial use.
