Professional Applications & Engineering Value
These 5-40 UNC brass rounded head slotted screws deliver critical performance in electrical enclosures, marine hardware, and precision instrumentation. The brass material inherently resists galvanic corrosion and offers non-sparking properties, essential in volatile environments. With a coarse thread spacing and Class 2A thread fit, they maintain tight tolerances and prevent loosening under dynamic loads. The fully threaded design ensures consistent clamping force across assemblies, while the slotted drive allows for quick maintenance and disassembly. Engineered to ASME B18.6.3, these screws provide reliable, repeatable fastening solutions for OEM and MRO applications where material integrity and regulatory adherence are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit and UNC coarse threads for precise dimensional accuracy. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met. The screws feature a right-hand thread direction, 0.125" thread diameter, and 5/8" length under the inch system, providing standardized interchangeability and reliability in industrial fastener systems.
