Professional Applications & Engineering Value
This 6-32 UNC brass set screw is engineered to address common industrial challenges such as component slippage, corrosion in aggressive settings, and the need for compact, reliable fastening. The Class 3A thread fit and coarse thread spacing ensure quick assembly with minimal cross-threading risk, while the cup tip provides a firm grip on shafts and collars without marring surfaces. Made from brass, it resists rust and galvanic corrosion, making it suitable for electrical enclosures, marine equipment, and precision machinery. The headless, hex drive design allows for unobtrusive installation in confined spaces, supporting maintenance efficiency and long-term operational stability in demanding applications.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision and UNC coarse thread standards with a 6-32 thread size. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial reliability. Dimensions include a 1/2" length, 0.138" thread diameter, and 1/16" hex drive size, all designed for consistent performance in technical fastening systems.
