Professional Applications & Engineering Value

These polycarbonate flat head screws address critical needs in electronics, medical devices, and optical assemblies where metal fasteners cause interference or corrosion. The clear plastic construction maintains aesthetic transparency while providing excellent dielectric properties. With 1/4-20 UNC coarse threading and Class 2A fit, these screws deliver consistent clamping force in plastic substrates without risk of galvanic corrosion. The 82° countersink ensures seamless integration into angled recesses, while the temperature resistance from -40° to 210°F ensures dimensional stability in controlled environments. Ideal for applications requiring non-conductive fasteners with regulatory compliance for global markets.
