Professional Applications & Engineering Value

Engineered for demanding industrial environments, these PTFE plastic flat head screws deliver exceptional performance where metal fasteners would fail. The white PTFE material provides outstanding chemical resistance while maintaining structural integrity across an extreme temperature range from -100° to 500° F. The 1/4"-20 UNC coarse thread with Class 2A fit ensures reliable engagement in plastic and soft materials, while the standard 82° countersink angle creates seamless flush mounting. These fully threaded slotted screws are particularly valuable in chemical processing, food equipment, electrical insulation, and high-purity applications where non-conductive, non-corrosive industrial plastic fasteners are essential.
