• Easy installation and removal with a 3mm hex drive and knurled low-profile socket head, offering secure grip and space-saving design.
• Accurate thread fit with Class 5g6g metric coarse threads (M5 x 0.8mm), ensuring consistent fastening and interchangeability.
• Compliance with environmental standards including RoHS 3 and REACH, making it safe for various global industrial applications.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered from alloy steel with a black oxide finish to address common industrial challenges like misalignment, corrosion, and high-stress fatigue. The 20mm shoulder length with precise tolerances ensures accurate positioning in assemblies, reducing wear on mating parts and preventing loosening under dynamic loads. Its coarse thread pitch and Class 5g6g fit provide quick, secure fastening in machinery, automation systems, and precision equipment. The low-profile socket head with knurling allows for easy access in confined spaces, while the high tensile strength supports heavy-duty applications, making it ideal for industrial shoulder screw uses in robotics, conveyors, and tooling fixtures.

Specification Summary & Compliance

This shoulder screw features an M5 x 0.8mm coarse metric thread with Class 5g6g tolerance for precise fit, a shoulder diameter of 6 mm (tolerance: -0.072 to -0.01 mm), and shoulder length of 20 mm (tolerance: 0 to 0.25 mm). Manufactured to high standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and reliability in industrial applications.
