Professional Applications & Engineering Value
These brass rounded head slotted screws provide critical solutions for electrical, marine, and plumbing applications where corrosion resistance and non-magnetic properties are essential. The 5-40 UNC coarse thread design ensures rapid installation and superior pull-out resistance in softer materials, while the Rockwell B40 hardness maintains thread integrity during repeated disassembly. The combination of fully threaded construction and rounded head profile distributes clamping force evenly, preventing damage to sensitive surfaces. These industrial screws are particularly valuable in electrical enclosures, instrumentation panels, and marine hardware where brass fasteners prevent galvanic corrosion and ensure long-term reliability.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent engagement. Features 5-40 UNC coarse threads with right-hand orientation and 1 1/2" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across regulated industries including electronics, marine, and industrial equipment manufacturing.
