• Optimized for high-shear applications with a minimum shear strength of 45,000 psi, providing dependable performance in dynamic assemblies.

Professional Applications & Engineering Value

This precision M5 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial machinery. The 70mm shoulder length acts as a precise axle or dowel, eliminating the need for separate bushings and reducing assembly parts count. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, which is vital for food processing, packaging, and outdoor equipment. The hex socket drive allows for high-torque installation in confined spaces, ensuring the screw remains securely fastened in high-vibration environments. Its coarse thread and robust tensile strength make it a reliable choice for securing moving parts in assemblies like linkages, gears, and pivoting arms, enhancing overall machine longevity and reducing maintenance downtime.

Specification Summary & Compliance

This shoulder screw features an M5x0.8 metric coarse thread with a Class 5g6g thread fit for standard industrial applications. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured to conform to ISO 7379 and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global markets and restricted substance standards.
