Professional Applications & Engineering Value

These 2-56 UNC brass slotted round head screws deliver exceptional performance in industrial applications where corrosion resistance and mechanical reliability are paramount. The brass material provides inherent protection against oxidation and galvanic corrosion, making these fully threaded screws ideal for electrical components, marine equipment, and plumbing systems. The rounded head profile with slotted drive ensures easy installation in confined spaces while maintaining a low-profile appearance. With coarse thread spacing and Class 2A thread fit, these fasteners offer superior holding power in softer materials and prevent cross-threading during assembly. The combination of 50,000 psi tensile strength and Rockwell B40 hardness ensures these screws withstand vibration and mechanical stress in demanding operational environments.

Specification Summary & Compliance

These rounded head screws feature precise dimensional accuracy with Class 2A thread fit per UNC standards and coarse thread spacing for optimal performance. Manufacturing strictly adheres to ASME B18.6.3 specifications ensuring consistent quality and dimensional uniformity. Environmental compliance is verified through RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, confirming the absence of restricted substances. The right-hand thread direction and fully threaded 1/4" length provide standardized installation across industrial applications while maintaining regulatory requirements for professional use.
