Professional Applications & Engineering Value

This 360 Brass shoulder screw is engineered to address critical alignment and durability challenges in precision machinery. The 1/2" shoulder diameter with precise fit tolerance provides a stable bearing surface for rotating parts, reducing wear and misalignment in assemblies like pivots, gears, and linkages. The UNC coarse thread and Class 2A thread fit ensure quick, secure fastening even in high-vibration environments, while the hex socket head allows for compact installation in confined spaces. Made from brass, it offers inherent corrosion resistance, making it suitable for electrical components, marine equipment, and food processing machinery where non-magnetic, non-sparking properties are essential. Combined with 40,000 psi tensile strength, this screw delivers reliable performance in automated systems, reducing downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder features a diameter tolerance of -0.002" to 0" and length tolerance of 0" to 0.003" for precise assembly. It complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, ensuring environmental safety in industrial applications.
