• Optimized for coarse UNC threading, allowing for quick assembly and reduced cross-threading risks in high-vibration settings

Professional Applications & Engineering Value

This 316 Stainless Steel shoulder screw is engineered to address common industrial challenges such as corrosion, misalignment, and mechanical stress. The Black Oxide finish not only enhances corrosion resistance but also reduces friction, making it ideal for applications in machinery, automotive assemblies, and marine equipment where exposure to moisture and chemicals is frequent. The UNC coarse thread and Class 3A fit ensure tight tolerances and reliable fastening in high-vibration environments, preventing loosening over time. With a knurled socket head and hex drive, it allows for precise torque control during installation, reducing assembly errors and improving operational efficiency. These features make it a top choice for precision engineering projects requiring durability and consistent performance under heavy loads.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision, ensuring dimensional accuracy in thread diameter (0.164") and spacing. The shoulder diameter and length maintain tight tolerances (e.g., shoulder diameter tolerance of -0.004" to -0.002") for reliable fit in assemblies. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use. Manufactured to deliver consistent hardness (Rockwell B79) and strength, it meets rigorous performance criteria for demanding applications.
