Professional Applications & Engineering Value
These zinc-plated steel flat head screws deliver exceptional engineering value in industrial applications where flush surface mounting and corrosion resistance are critical. The combination of UNC coarse threading and Class 2A thread fit ensures rapid installation in metal assemblies, electrical enclosures, and machinery components while minimizing the risk of thread stripping. The fully threaded design provides maximum engagement in thin materials, making them ideal for sheet metal work, panel fastening, and equipment manufacturing where vibration resistance and consistent clamping force are essential. The 82° countersink angle creates a secure, flush fit that prevents snagging while maintaining structural integrity under load.
Specification Summary & Compliance
This 6-32 x 1-1/2" flat head slotted screw features precision UNC coarse thread spacing with Class 2A thread fit tolerance for consistent dimensional accuracy. Manufactured to ASME B18.6.3 specifications, the fastener ensures reliable performance in inch-system applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and material restrictions adherence for global industrial use.
