Professional Applications & Engineering Value
This nylon plastic flat head screw with 2-56 UNC coarse threading solves critical engineering challenges in applications where metal fasteners would fail. The non-conductive properties make it ideal for electrical enclosures, circuit boards, and electronic devices where short-circuit prevention is paramount. Its inherent corrosion resistance eliminates galvanic compatibility issues in marine, chemical processing, and outdoor equipment. The standard 82° countersink and slotted drive design facilitate quick installation in plastic assemblies, automotive trim, and consumer products while maintaining clean aesthetics. With temperature resistance spanning -40° to 185°F, this fastener delivers consistent performance in environments where thermal expansion would compromise metal alternatives.
Specification Summary & Compliance
This 2-56 UNC flat head screw features Class 2A thread fit per inch system standards, ensuring precise dimensional accuracy and interchangeability. Manufacturing complies with ASME B18.6.3 specifications for consistent quality and performance. The product is RoHS 3 (2015/863/EU) compliant, containing no restricted hazardous substances, and meets industry standards for right-hand threaded, fully threaded fasteners with standard flat head profile and coarse thread spacing.
