Professional Applications & Engineering Value

These 6-32 UNC oval head slotted machine screws are engineered to address common industrial challenges such as fastener corrosion, thread stripping, and installation inefficiency. Made from 18-8 Stainless Steel with a passivated finish, they resist rust and chemical exposure in demanding settings like electronics enclosures, machinery panels, and automotive assemblies. The coarse thread spacing and Class 2A thread fit reduce cross-threading risks while enabling quick fastening. The oval head design sits flush with surfaces, minimizing protrusion and improving safety. Ideal for flat head screw applications requiring both aesthetic appeal and structural reliability, these screws ensure consistent performance under vibration and load, supported by full threading for enhanced holding power.

Specification Summary & Compliance

This screw adheres to ASME B18.6.3 specifications, with precise Class 2A thread fit and UNC coarse threads for consistent dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The manufacturing process guarantees a right-hand thread direction, 82° countersink angle, and fully threaded 1/2" length, meeting industrial standards for reliability and interchangeability.
