• Precise alignment and spacing with a 16 mm shoulder length and tight tolerances, reducing assembly errors.
• Wide compatibility and easy installation due to the M5 coarse thread and Class 5g6g fit, speeding up production processes.
• Compliance with environmental standards including RoHS 3 and REACH, meeting global regulatory requirements for safe use.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address common industrial challenges, such as component misalignment and vibration-induced loosening. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for applications in machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The black oxide finish not only enhances aesthetics but also adds a protective layer that reduces friction and wear. With a knurled socket head and precise metric thread design, it ensures secure fastening in high-stress environments, improving overall equipment reliability and reducing downtime. Ideal for use in precision instruments and heavy-duty fixtures, this screw delivers consistent performance where accuracy and strength are critical.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M5 thread size, 0.8 mm coarse pitch, and Class 5g6g thread fit for precise engagement. Dimensions include a shoulder diameter of 5 mm (tolerance: -0.04 to -0.01 mm) and shoulder length of 16 mm (tolerance: 0 to 0.25 mm), ensuring high accuracy in assembly. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, it supports environmentally responsible sourcing and usage in various industrial sectors.
