Professional Applications & Engineering Value
Engineered for precision fastening in electrical enclosures, automotive components, and consumer electronics, these nylon plastic flat head screws solve critical challenges where metal fasteners fail. The non-conductive properties eliminate electrical short risks while providing excellent chemical resistance against oils and solvents. The UNC coarse thread pattern with Class 2A tolerance ensures secure engagement in plastic housings and soft substrates without stripping. With 100° countersink geometry meeting ASME B18.6.3 specifications, these screws deliver flush surface mounting for aerodynamic and aesthetic applications. The temperature-resistant nylon material maintains dimensional stability from freezing conditions to elevated temperatures, making them ideal for outdoor equipment and thermal cycling environments.
Specification Summary & Compliance
This 2-56 UNC screw features Class 2A thread fit precision with 1/4" length and fully threaded coarse spacing. Manufacturing complies with ASME B18.6.3 mechanical standards for dimensional accuracy and RoHS 3 (2015/863/EU) environmental regulations. The right-hand thread direction and standard flat head profile ensure compatibility with industry-standard installation tools and procedures.
