Professional Applications & Engineering Value

This 360 Brass shoulder screw is engineered to address critical alignment and wear challenges in precision assemblies. The 1-1/2" shoulder length with minimal tolerances ensures exact component positioning, reducing misalignment and wear in rotating parts, pivots, and guides. The 10-32 UNF fine thread and Class 2A fit provide secure fastening in applications subject to vibration, such as machinery, electronics, and automotive systems. Made from 360 Brass, it offers excellent corrosion resistance and non-magnetic properties, making it suitable for electrical and marine environments. The socket head design allows for compact installations where space is limited, enhancing the screw's utility in complex industrial equipment and precision instruments.

Specification Summary & Compliance

The screw features a 10-32 UNF thread with Class 2A thread fit for precise engagement, and a shoulder diameter of 1/4" with a tolerance of -0.002" to 0", and shoulder length of 1-1/2" with a tolerance of 0" to 0.003" for accurate assembly. It complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006), ensuring adherence to environmental and safety standards for industrial components.
