Professional Applications & Engineering Value
Engineered for precision and durability, these 8-32 UNC flat head machine screws address common industrial challenges such as material degradation and assembly inefficiency. The Black-Oxide 18-8 Stainless Steel provides excellent resistance to rust and oxidation, making them suitable for outdoor equipment, marine hardware, and chemical processing facilities. The undercut flat head profile and 82° countersink angle ensure a seamless fit in countersunk holes, reducing protrusion and preventing interference in tight spaces. Combined with the coarse UNC threads and No. 2 Phillips drive, these screws enable quick, secure fastening in metal, plastic, and composite assemblies, enhancing productivity and minimizing maintenance needs in industrial screw applications.
Specification Summary & Compliance
This screw features a 1/4" length with fully threaded 8-32 UNC coarse threads and Class 2A thread fit for consistent dimensional accuracy. It meets ASME B18.6.3 specifications for machine screws and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
