Professional Applications & Engineering Value
This M5 shoulder screw is engineered to solve critical alignment and corrosion challenges in industrial assemblies. The 316 Stainless Steel material provides exceptional resistance to chemicals, saltwater, and oxidation, making it ideal for food processing, marine, and pharmaceutical equipment. The shoulder design acts as a precise locating dowel, eliminating the need for additional bushings and reducing component wear in rotating mechanisms like conveyor systems and precision machinery. With its Class 5g6g thread and coarse pitch, it ensures rapid, secure fastening in high-vibration environments, while the socket head with 3 mm hex drive offers compact installation in space-constrained applications.
Specification Summary & Compliance
This precision metric shoulder screw features M5 x 0.8 mm coarse thread with Class 5g6g thread fit per ISO standards. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. Manufactured from 316 Stainless Steel with Rockwell B79 hardness and 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for safe and sustainable use.
