Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in machinery. The alloy steel construction and black oxide finish provide superior strength and corrosion resistance, making it suitable for precision applications like pivots, gears, and linkages. The 40mm shoulder length with minimal tolerances ensures exact positioning, reducing stress on threads and enhancing assembly longevity. Its right-hand metric thread and coarse pitch facilitate quick installation in automated systems, while the socket head with hex drive allows for tight spaces and high-torque requirements. Ideal for robotics, automotive, and manufacturing equipment, this screw delivers reliable performance in industrial shoulder screw applications.
Specification Summary & Compliance
The screw adheres to Class 5g6g thread fit for precise metric threading, with shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm. It meets ASTM A108 specifications for material quality, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial reliability.
