Professional Applications & Engineering Value
Engineered for demanding environments where metal fasteners fail, these nylon flat head screws solve critical challenges in electrical, marine, and corrosion-sensitive applications. The nylon plastic construction provides inherent resistance to rust, chemicals, and galvanic corrosion while offering excellent dielectric properties for electrical insulation. The 1/4-20 UNC coarse threading with Class 2A fit ensures reliable engagement in plastics, wood, and soft metals, while the standard flat head profile with 82° countersink allows for flush installation in visible areas. These fully threaded screws deliver maximum holding power across the entire 1-1/2" length, making them ideal for assemblies requiring vibration resistance and long-term reliability in temperature ranges from -40°F to 185°F.
Specification Summary & Compliance
This 1/4-20 UNC threaded screw features Class 2A thread fit tolerances and fully threaded design with standard 82° countersink angle. Manufactured in compliance with ASME B18.6.3 specifications for dimensional accuracy and performance standards. The product is RoHS 3 (2015/863/EU) compliant, ensuring environmental safety and regulatory adherence for global industrial applications.
