Professional Applications & Engineering Value

These clear polycarbonate pan head screws deliver critical advantages in applications where metal fasteners fail. The polycarbonate material maintains dimensional stability across wide temperature fluctuations (-40° to 210°F), preventing thermal expansion issues that compromise assembly integrity. The fully threaded 2-56 UNC coarse thread configuration with Class 2A fit ensures rapid installation in plastic housings and electronic enclosures while reducing stress concentration. The transparent design proves invaluable in optical equipment, medical devices, and display assemblies where visual inspection and aesthetic consistency are paramount. Unlike metallic alternatives, these Phillips drive screws eliminate galvanic corrosion risks in mixed-material assemblies while providing excellent electrical insulation properties.

Specification Summary & Compliance

This fastener features 2-56 UNC coarse threads with Class 2A thread fit tolerances, right-hand threading, and a standard pan head profile with 0.17" diameter. Manufacturing complies with RoHS 3 (2015/863/EU) environmental regulations, ensuring restriction of hazardous substances for electronics and industrial applications. The fully threaded 1/2" length provides consistent engagement while the Phillips No. 1 drive maintains compatibility with standard installation tools.
