Professional Applications & Engineering Value
This 316 Stainless Steel Shoulder Screw is engineered to address critical challenges in industrial settings where corrosion resistance and precision alignment are paramount. The UNC coarse thread and Class 3A fit provide tight tolerances that prevent loosening under vibration, making it ideal for machinery, automotive assemblies, and electronic enclosures. The knurled head and hex socket drive enable secure handling and high torque application, reducing the risk of stripping during installation. With a shoulder diameter and length designed for exact positioning, it ensures components like gears and pulleys remain accurately aligned, enhancing overall system reliability and reducing maintenance downtime in corrosive or high-stress environments.
Specification Summary & Compliance
This shoulder screw features precision 8-32 UNC coarse threads with a Class 3A fit for tight dimensional accuracy, ensuring reliable engagement. The shoulder diameter and length adhere to standard tolerances (e.g., shoulder diameter: -0.004" to -0.002"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
