Professional Applications & Engineering Value
This 4-40 UNC brass pan head slotted screw is engineered to address common challenges in precision assemblies, such as corrosion-induced failure and inconsistent thread performance. The brass material offers inherent resistance to rust and galvanic corrosion, making it suitable for electrical components, marine hardware, and plumbing systems. Its coarse thread and Class 2A fit ensure quick, secure fastening in softer materials or pre-tapped holes, reducing installation time and minimizing strip-out risks. The rounded pan head with a slotted drive provides a low-profile, tool-accessible solution for applications where space is limited but reliability is critical, enhancing the longevity and maintenance efficiency of your equipment.
Specification Summary & Compliance
This screw adheres to ASME B18.6.3 specifications for dimensional consistency and performance. Threads are manufactured to UNC coarse standards with a Class 2A fit for precise tolerance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and safe for various industrial and consumer applications.
