Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel and Black Oxide finish, ideal for harsh environments and extending service life.
- High tensile and shear strength (70,000 psi tensile, 35,000 psi min shear) ensures reliable performance in heavy-duty applications.
- Precision thread fit (Class 5g6g) for smooth assembly, reduced wear, and secure fastening in dynamic loads.
- Knurled socket head with hex drive provides excellent grip and torque transmission, minimizing tool slippage during installation.
- Long 130mm shoulder offers stable alignment and acts as a pivot or shaft, reducing component wear and simplifying assembly.
- Compliance with ISO 7379, RoHS 3, and REACH guarantees quality, safety, and environmental standards for global industrial use.
- Durable Rockwell B79 hardness maintains structural integrity under stress, ensuring long-term reliability.
Professional Applications & Engineering Value
This M12x1.75 shoulder screw is engineered to address common industrial challenges, such as misalignment and corrosion-induced failure. Made from 316 Stainless Steel with a Black Oxide finish, it resists aggressive chemicals and moisture, making it perfect for machinery, automotive, and marine applications. The 130mm shoulder length provides a precise bearing surface, reducing friction and wear in rotating assemblies, while the coarse thread and Class 5g6g fit ensure quick, secure fastening. Its socket head with knurled texture enhances tool engagement, speeding up installation in tight spaces and improving overall efficiency in production lines.
Specification Summary & Compliance
This shoulder screw features a Metric M12x1.75 coarse thread with Class 5g6g thread fit for high precision. Dimensions include an 18mm thread length, 130mm shoulder length (tolerance 0 to 0.25 mm), and 16mm shoulder diameter (tolerance -0.072 to -0.01 mm). It meets ISO 7379 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and reliability in industrial use.
