Professional Applications & Engineering Value
This M8 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for machinery, automotive assemblies, and electronic enclosures exposed to moisture. The 30mm shoulder length acts as a precise locating dowel, minimizing misalignment and wear on mating parts, while the coarse thread pitch ensures rapid and secure fastening. The hex socket drive and knurled head facilitate easy installation in tight spaces, reducing assembly time and improving operational efficiency in high-vibration environments.
Specification Summary & Compliance
This metric shoulder screw features an M8 x 1.25mm coarse thread with a Class 5g6g thread fit for standard tolerance. The shoulder diameter tolerance is -0.04 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring precise dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its adherence to environmental and safety regulations for industrial use.
