Professional Applications & Engineering Value
Engineered for precision assemblies requiring corrosion-resistant fastening solutions, these 2-56 UNC brass screws deliver exceptional performance in electrical enclosures, instrumentation panels, and marine components. The rounded button head design combined with Class 3A thread fit eliminates galling issues common in brass fasteners while maintaining precise alignment. The fully threaded construction ensures maximum grip length in thin materials, while the coarse thread spacing provides superior pull-out resistance in soft substrates. With hex drive compatibility and right-hand threading, these screws enable rapid installation in high-volume production environments where reliability and regulatory compliance are paramount.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit precision and UNC coarse thread specifications. The 3/8" length maintains dimensional accuracy within industrial tolerances. Compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The fully threaded design and right-hand thread direction adhere to industry-standard fastening protocols for consistent performance across applications.
