Professional Applications & Engineering Value
This M3 shoulder screw delivers critical engineering value in precision assembly applications where alignment and spacing accuracy are paramount. The 316 stainless steel material provides exceptional corrosion resistance, making it ideal for marine, chemical processing, and food industry equipment where moisture and corrosive agents are present. The black oxide finish enhances surface durability while reducing friction during installation. With its Class 5g6g thread fit and precisely controlled shoulder diameter, this component ensures perfect alignment in machinery, robotics, and precision instruments. The knurled socket head design allows for secure tool engagement in confined spaces, preventing costly installation errors and maintenance downtime in industrial settings.
Specification Summary & Compliance
This precision shoulder screw features M3 x 0.5mm coarse pitch metric thread with Class 5g6g tolerance for optimal fit. The shoulder diameter maintains tight tolerance of -0.072 to -0.01 mm, while shoulder length tolerance is controlled within 0 to 0.25 mm. Manufactured from 316 stainless steel with black oxide finish, the component achieves Rockwell B79 hardness. The screw fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial applications worldwide.
