Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The precision-machined 25mm shoulder acts as a pivot, bearing surface, or spacer, eliminating the need for additional components and reducing assembly errors in machinery, automotive jigs, and conveyor systems. Manufactured from 316 Stainless Steel, it provides exceptional resistance to corrosion from chemicals, moisture, and extreme temperatures, ensuring longevity in aggressive environments. The Class 5g6g thread fit and coarse M8x1.25 thread facilitate quick assembly while maintaining a secure hold against vibrations. The combination of a knurled head and hex drive allows for high-torque installation without slippage, making it a reliable choice for high-stress precision shoulder screw applications where failure is not an option.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy for the M8x1.25 coarse thread. The shoulder diameter tolerance is -0.072 to -0.01 mm and shoulder length tolerance is 0 to 0.25 mm, guaranteeing precise fits. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated industries without hazardous substances.
