Professional Applications & Engineering Value

This 360 brass shoulder screw is engineered to solve critical alignment and corrosion challenges in precision assemblies. The UNC coarse thread and Class 2A fit provide fast, reliable engagement, reducing assembly time while the precisely machined shoulder acts as a pivot, bearing surface, or locator, eliminating the need for additional spacers or bushings. Made from high-strength brass, it offers excellent electrical conductivity and resistance to galvanic corrosion, making it indispensable in electronics, instrumentation, and marine applications. The hex socket drive ensures a secure grip for high-torque applications, maintaining performance in industrial machinery and automated systems where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This shoulder screw conforms to UNC thread standards with a Class 2A thread fit for consistent, interchangeable assembly. The shoulder features precise dimensional tolerances (diameter: -0.002" to 0", length: 0" to 0.003") ensuring accurate location and fit. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006) adherence, confirming its suitability for use in regulated and international markets.
