Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Precise alignment and smooth rotation due to the accurately machined shoulder with controlled diameter and length tolerances.
- High mechanical strength and durability from a Rockwell B55 hardness and 70,000 psi tensile strength, preventing failure under load.
- Secure and flush mounting enabled by the low-profile socket head, saving space and providing a clean finish.
- Reliable and coarse thread engagement with a Class 6g fit, ensuring easy assembly and strong holding power in various materials.
- Broad industry compatibility through compliance with DIN 923, RoHS 3, and REACH standards for quality and environmental safety.
- Optimized for metric applications with an M8x1.25 coarse thread and right-hand direction, simplifying sourcing and installation.
Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and wear issues in precision assemblies. The 18-8 stainless steel material offers excellent corrosion resistance, making it suitable for machinery, automotive, and electronics where exposure to moisture or chemicals is a concern. The precise shoulder fit and low socket head design ensure components like gears, pulleys, and linkages are accurately positioned and rotate smoothly without misalignment. With a coarse thread and Class 6g thread fit, it provides quick, secure fastening in demanding applications, reducing assembly time and enhancing operational reliability in industrial equipment and automation systems.
Specification Summary & Compliance
This shoulder screw adheres to DIN 923 specifications, with a Class 6g thread fit and precise shoulder dimensions (diameter: 10 mm with -0.036 to 0 mm tolerance; length: 16 mm with 0.1 to 0.2 mm tolerance). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for global supply chains.
