Professional Applications & Engineering Value

These 4-40 UNC PTFE plastic screws deliver critical performance advantages in demanding industrial environments where metal fasteners fail. The PTFE material provides inherent chemical resistance against corrosive substances while maintaining structural integrity across an extreme temperature range from -100° to 500° F. The rounded head slotted design with Class 2A thread fit ensures reliable installation in coarse thread applications requiring vibration resistance. These screws are particularly valuable in electrical insulation scenarios, chemical processing equipment, food machinery, and laboratory instrumentation where non-conductive, non-reactive fastening solutions are essential. The fully threaded configuration maximizes surface contact for superior retention in plastic and soft material assemblies.

Specification Summary & Compliance

This 4-40 UNC plastic screw features precision Class 2A thread fit with right-hand coarse threading and standard rounded head profile. Manufactured to exacting dimensional standards with 0.211" head diameter, 0.086" head height, and 5/8" length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications while meeting international manufacturing standards for plastic fasteners.
