Professional Applications & Engineering Value

This 5-40 UNC brass pan head slotted screw delivers exceptional engineering value across multiple industrial sectors. The brass construction provides natural corrosion resistance, making it ideal for electrical components, marine equipment, and plumbing systems where moisture resistance is critical. The coarse UNC threading and Class 2A thread fit ensure rapid assembly and reliable performance in vibration-prone applications. With full threading along the 1-1/2" length, engineers achieve maximum thread engagement for secure fastening in demanding mechanical assemblies. The combination of 50,000 psi tensile strength and Rockwell B40 hardness provides durability against mechanical stress while maintaining the machinability advantages of brass. These rounded head screws are particularly valuable in applications requiring non-sparking properties and excellent electrical conductivity.

Specification Summary & Compliance
