Professional Applications & Engineering Value
This 5/16"-24 UNF brass rounded head screw is engineered to address critical challenges in precision assembly and corrosive environments. The brass material inherently resists rust and galvanic corrosion, making it a top choice for electrical components, marine hardware, and plumbing systems. The Class 3A thread fit and UNF fine threading provide a tighter, more precise engagement than coarse threads, significantly reducing the risk of loosening under vibration—a common failure point in machinery and automotive applications. Combined with the button head style and hex drive, it offers a low-profile, flush finish with easy installation in confined spaces. This fastener delivers reliable tensile strength and durability where both mechanical performance and material compatibility are paramount.
Specification Summary & Compliance
This screw features a 5/16"-24 UNF fine thread with a precision Class 3A thread fit for superior dimensional accuracy. It is manufactured to deliver a tensile strength of 50,000 psi and Rockwell B55 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and is REACH (EC 1907/2006) compliant, meeting stringent industrial safety and environmental standards.
