Professional Applications & Engineering Value

These Nylon Plastic screws with a 4-40 UNC coarse thread and pan head are engineered to address common industrial challenges such as galvanic corrosion and electrical conductivity risks. The non-conductive and corrosion-resistant properties make them indispensable in electrical enclosures, control panels, and outdoor equipment where metal fasteners would fail. The fully threaded design and Class 2A thread fit provide consistent clamping force and vibration resistance, ensuring long-term reliability in assemblies exposed to temperature fluctuations from -40° to 185° F. By utilizing a Phillips No. 1 drive, these screws enable quick and efficient installation, reducing labor time in high-volume production settings.

Specification Summary & Compliance

This screw features a 1/2" length, 0.215" head diameter, and conforms to UNC thread standards with a Class 2A thread fit for precise dimensional accuracy. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to strict environmental and safety guidelines for hazardous substances.
