Professional Applications & Engineering Value
This M8 shoulder screw delivers critical engineering solutions in demanding sectors like machinery assembly, automation systems, and precision equipment. The 316 stainless steel material provides excellent resistance to corrosion and oxidation, extending service life in humid or chemically aggressive settings. Its 50mm shoulder length with controlled diameter tolerance acts as a precise pivot or spacer, reducing wear and misalignment in rotating parts. The hex socket drive with knurled texture ensures firm tool grip, preventing cam-out during high-torque tightening. With a coarse thread pitch of 1.25mm, it offers faster installation and enhanced resistance to loosening under dynamic loads, making it ideal for industrial applications requiring durability and dimensional accuracy.
Specification Summary & Compliance
This shoulder screw features an M8x1.25mm metric coarse thread with Class 5g6g thread fit for standardized compatibility. 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. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, it adheres to strict environmental and safety regulations for industrial use.
