Professional Applications & Engineering Value

These clear polycarbonate screws with 2-56 UNC coarse threads solve critical challenges in electronics, medical devices, and display applications where metal fasteners can cause short circuits or corrosion. The polycarbonate material maintains dimensional stability across the broad temperature range of -40° to 210° F, preventing thermal expansion issues that compromise fastener integrity. The Class 2A thread fit ensures consistent engagement in plastic components without stripping, while the fully threaded design provides maximum thread contact in thin materials. The transparent nature allows for visual verification of proper installation and complements products where aesthetics are important, making these Phillips drive screws ideal for consumer electronics, laboratory equipment, and optical assemblies.

Specification Summary & Compliance
