Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for applications in electronics, machinery, and automotive systems where exposure to moisture or chemicals is common. The integrated shoulder with controlled diameter and length tolerances acts as a precise spacer or pivot, reducing wear on moving parts and maintaining accurate component positioning. Combined with the hex socket drive, it allows for high-torque installation without damaging the head, ensuring reliable performance in industrial shoulder screw applications that demand both strength and repeatability.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for precise dimensional control. It conforms to ISO 7379 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards.
