Key Features & Benefits at a Glance
- Enhanced corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
- Superior mechanical strength with 70,000 PSI tensile and 45,000 PSI shear strength for reliable, heavy-duty performance.
- Precise component alignment enabled by the 60mm shoulder length with tight tolerances, reducing assembly errors.
- Secure, non-slip fastening thanks to the knurled socket head and hex drive, allowing for high-torque applications.
- Consistent thread engagement with Class 5g6g thread fit and coarse M8x1.25 pitch for quick, stable installations.
- Long-term durability supported by Rockwell B83 hardness, resisting wear and deformation under stress.
- Global compliance assurance meeting ISO 7379 standards and RoHS 3 & REACH regulations for safe, international use.
Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision machinery, automated systems, and heavy-duty equipment. The 18-8 Stainless Steel material provides excellent corrosion resistance, essential for operations in moist or chemically aggressive settings. Its 60mm shoulder length with minimal tolerance ensures accurate positioning of moving parts, such as gears and pulleys, reducing vibration and misalignment. The coarse thread (M8x1.25) and Class 5g6g thread fit facilitate rapid assembly while maintaining high strength, making it ideal for applications requiring repeated adjustments. Combined with a knurled socket head for secure tool grip, this fastener enhances operational reliability and minimizes downtime in demanding industrial environments.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, ensuring dimensional accuracy with a Class 5g6g thread fit and shoulder diameter tolerance of -0.072 to -0.01 mm. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material integrity for global supply chains.
