Professional Applications & Engineering Value

This 316 Stainless Steel shoulder screw with a Black Oxide finish is engineered to address critical challenges in precision machinery, automation systems, and marine equipment. Its UNC coarse threading and Class 3A fit provide secure fastening in high-vibration environments, reducing the risk of loosening. The knurled socket head allows for reliable torque application, while the precisely machined shoulder ensures accurate alignment of moving parts like gears and pulleys. With excellent corrosion resistance and high tensile strength, it is ideal for applications requiring long-term reliability under demanding conditions, such as in chemical processing or outdoor industrial settings.

Specification Summary & Compliance

This shoulder screw features a Class 3A thread fit for high precision, with UNC coarse threading (8-32 size) and a right-hand thread direction. The shoulder diameter and length are manufactured to tight tolerances (e.g., shoulder diameter: -0.004" to -0.002"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and regulatory adherence for industrial use.
