- Enhanced torque transmission and grip from the knurled socket head design with 5mm hex drive
- Precise component alignment and spacing ensured by the 10mm shoulder diameter with tight tolerance control
- High mechanical strength and durability with 70,000 psi tensile strength and 35,000 psi shear strength
- Reliable coarse thread engagement (M8 x 1.25mm) for faster assembly and reduced cross-threading risk
- Consistent dimensional accuracy maintained through ISO 7379 compliance and Class 5g6g thread fit
- Safe for sensitive applications with full RoHS 3 and REACH environmental compliance
Professional Applications & Engineering Value
This M8 shoulder screw in 316 stainless steel is engineered to solve critical alignment and corrosion challenges in precision assemblies. The 10mm shoulder diameter provides a secure pivot point for rotating parts, eliminating the need for separate spacers and reducing assembly time. The knurled socket head with 5mm hex drive ensures maximum torque application without slippage, even in high-vibration environments. With its coarse thread and 18mm shoulder length, it offers rapid installation in machinery, automation systems, and optical equipment where corrosion resistance and dimensional stability are paramount. The combination of high tensile strength and ISO-standard manufacturing guarantees long-term reliability in demanding industrial applications.
Specification Summary & Compliance
This shoulder screw features M8 x 1.25mm coarse metric threads with Class 5g6g thread fit for standard clearance applications. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise fit in machined components. Manufacturing and quality adhere to ISO 7379 specifications, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
