Professional Applications & Engineering Value

This 316 Stainless Steel Shoulder Screw is engineered to address critical challenges in precision machinery and assembly lines. The UNC coarse thread and Class 3A fit provide excellent engagement and vibration resistance, reducing the risk of loosening in dynamic applications. The Black Oxide finish not only enhances corrosion resistance but also minimizes galling, a common issue in stainless steel fasteners. With a robust shoulder diameter of 3/16" and precise length tolerances, it ensures accurate pivot points and bearing surfaces in linkages, rollers, and jigs. This makes it an indispensable component for industries requiring high tensile strength and reliable alignment, from automotive manufacturing to packaging equipment, where downtime from fastener failure is not an option.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precise, secure fastening. Dimensional tolerances include a shoulder diameter of 3/16" (tolerance: -0.004" to -0.002") and shoulder length of 1 5/8" (tolerance: -0.005" to 0.005"), ensuring consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industrial and international applications.
