Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel material and passivated finish, ideal for harsh industrial environments
- Precise alignment and positioning ensured by the 10mm shoulder diameter with tight tolerance for reliable assembly
- High mechanical strength with 70,000 psi tensile strength and Rockwell B79 hardness for demanding applications
- Secure and efficient installation using the 5mm hex drive socket head, preventing stripping and ensuring consistent torque
- Accurate thread engagement with Class 6g fit and M8x1.25 coarse thread for quick assembly and vibration resistance
- Durable construction that meets RoHS 3 and REACH compliance, supporting sustainable and safe manufacturing practices
- Optimized dimensional stability from the 30mm shoulder length with minimal tolerance, reducing play in precision mechanisms
Professional Applications & Engineering Value
This M8 shoulder screw in 316 stainless steel with a passivated finish is engineered to address critical challenges in precision assemblies, such as misalignment and corrosion-induced failures. The socket head hex drive allows for high-torque installation in confined spaces, while the Class 6g thread fit ensures reliable fastening in dynamic environments. Commonly used in machinery, automotive, and electronics, the screw's precise shoulder diameter and length provide stable rotational support for bearings, pulleys, and linkages, minimizing wear and extending service life. Its robust tensile strength and hardness make it suitable for high-stress applications, offering long-term reliability and reduced maintenance costs.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with key specifications including M8x1.25 coarse thread, Class 6g thread fit, 10mm shoulder diameter (tolerance: -0.025 to 0 mm), and 30mm shoulder length (tolerance: 0 to 0.05 mm). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
