Professional Applications & Engineering Value
This M8 shoulder screw delivers exceptional engineering value in precision assemblies requiring exact component positioning. The 50mm shoulder length with precise diameter control provides superior bearing surface for rotating parts, eliminating the need for additional spacers in machinery, conveyor systems, and automation equipment. Manufactured from 18-8 stainless steel with passivated finish, it resists corrosion in demanding environments while maintaining dimensional stability. The low-profile socket head design allows installation in tight spaces without compromising torque transmission, making these metric shoulder screws ideal for CNC machinery, robotic arms, and precision instruments where vibration resistance and alignment accuracy are critical.
Specification Summary & Compliance
This precision shoulder screw features M8x1.25 coarse thread with Class 6g thread fit per metric standards, ensuring reliable engagement. The shoulder maintains precise dimensional control with diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm. Manufactured to industry specifications with Rockwell B95 hardness and 80,000 psi tensile strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use in global manufacturing applications.
