Professional Applications & Engineering Value
This 360 Brass shoulder screw is engineered to address critical alignment and corrosion challenges in industrial applications. The precise shoulder diameter and length provide exact positioning for moving parts in machinery, reducing wear and preventing misalignment in assemblies like pivots, gears, and linkages. The coarse UNC thread ensures quick and secure fastening, even in vibrating environments, while the hex socket head allows for high-torque installation in confined spaces. Made from durable brass, it offers excellent conductivity and resistance to galvanic corrosion, making it ideal for electrical components, marine equipment, and precision instruments where reliability is paramount.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit for consistent engagement and a precise shoulder with diameter tolerance of -0.002" to 0" and length tolerance of 0" to 0.003". It conforms to UNC thread standards with 5/16"-18 coarse threading and is manufactured from 360 Brass. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations for industrial use.
