- Enhanced torque transmission and grip thanks to the knurled socket head and 4mm hex drive, reducing tool slippage during installation.
- Precise component alignment and pivot points enabled by the 8mm diameter shoulder with tight diameter tolerance for consistent assembly.
- High mechanical strength with 70,000 psi tensile and 45,000 psi minimum shear strength, ensuring durability under load.
- Reliable thread engagement with Class 5g6g thread fit and coarse M5x0.8 thread, facilitating quick assembly and vibration resistance.
- Broad industrial compatibility through compliance with ISO 7379 standards, ensuring interchangeability and quality.
- Environmental and safety compliance with RoHS 3 and REACH, making it suitable for regulated industries.
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and wear issues in precision machinery, automated assemblies, and rotational bearing supports. The 18-8 stainless steel material offers excellent corrosion resistance, reducing maintenance in humid or chemical-exposed settings. Its 8mm shoulder diameter with minimal tolerance provides a stable pivot or spacer, preventing misalignment and extending component life. The knurled socket head and 4mm hex drive ensure secure tool engagement, minimizing stripping and enabling high-torque applications. With a coarse thread pitch and Class 5g6g fit, it resists loosening under vibration, making it ideal for dynamic industrial equipment. Compliant with ISO 7379, it guarantees consistency in global engineering projects.
Specification Summary & Compliance
This shoulder screw features precise dimensions: shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm, with a Class 5g6g thread fit for accurate assembly. It meets ISO 7379 manufacturing specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safety and sustainability in industrial use.
