Professional Applications & Engineering Value

This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision assembly and machinery. The Class 3A thread fit ensures minimal backlash and secure fastening in high-vibration environments, such as robotics, automotive fixtures, and conveyor systems. The knurled socket head enhances torque transmission and prevents cam-out during installation, while the UNC coarse thread facilitates rapid assembly and disassembly without compromising strength. Its corrosion-resistant properties make it suitable for marine, chemical processing, and food-grade equipment, where exposure to moisture and aggressive agents is common. By combining a precision-machined shoulder with high tensile and shear strength, this fastener provides reliable pivoting, alignment, and load-bearing functions in demanding industrial applications.

Specification Summary & Compliance

This shoulder screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for precise engagement and a shoulder diameter tolerance of -0.004" to -0.002". The UNC 10-24 coarse thread and standardized shoulder design ensure consistent performance. 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.
