Professional Applications & Engineering Value
This 4-40 UNC nylon plastic socket head cap screw delivers critical advantages in applications where metal fasteners fail. Its nylon material inherently resists corrosion, chemicals, and moisture, making it perfect for electronics, marine, and food processing equipment. The coarse UNC thread and Class 2A fit ensure quick assembly and reliable hold in plastic or soft materials, reducing stripping risks. With a 3/32" hex drive, it allows for high-torque installation in confined spaces, while the temperature range of -40° to 140°F supports use in outdoor or thermally variable settings. Engineers value its RoHS 3 compliance for sustainable designs and its electrical insulation for preventing galvanic corrosion.
Specification Summary & Compliance
This screw features a 4-40 UNC coarse thread with Class 2A thread fit for standard inch-system tolerances, ensuring interchangeability and precise alignment. It is fully threaded and measures 5/8" in length with a right-hand thread direction. Manufactured to common industrial specs, it complies with RoHS 3 (2015/863/EU) regulations, confirming the absence of hazardous substances for safe use in global markets.
