Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 Stainless Steel material offers excellent corrosion resistance, making it suitable for machinery, automotive, and electronics exposed to moisture or chemicals. The 16mm shoulder length with minimal tolerance acts as a precise pivot or spacer, minimizing misalignment and wear in rotating parts like gears and pulleys. Combined with the hex socket drive and Class 5g6g thread, it ensures easy, secure fastening in tight spaces, reducing installation time and improving overall mechanical integrity. Ideal for industrial fastening where high strength and dimensional accuracy are paramount.
Specification Summary & Compliance
This shoulder screw features an M5x0.8 coarse thread with a Class 5g6g thread fit per metric standards, ensuring precise engagement. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing high dimensional accuracy. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and safe for various industrial applications.
