Professional Applications & Engineering Value

This M4 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 316 stainless steel material offers exceptional resistance to corrosion and oxidation, making it suitable for medical devices, food processing equipment, and marine applications. The integrated 5mm shoulder acts as a precise pivot or spacer, eliminating the need for additional components and reducing play in rotating parts like gears and bearings. Combined with the Class 5g6g coarse thread and hex socket drive, it ensures quick, secure fastening in high-vibration environments, enhancing overall machinery reliability and reducing maintenance downtime.

Specification Summary & Compliance

This shoulder screw conforms to metric (M4 x 0.7mm) coarse thread standards with a Class 5g6g thread fit for consistent performance. The shoulder diameter tolerance is -0.072 to -0.01 mm and shoulder length tolerance is 0 to 0.25 mm, ensuring precise dimensional control. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, guaranteeing the absence of restricted hazardous substances for safe use in regulated industries.
