Professional Applications & Engineering Value

These clear polycarbonate flat head screws provide an ideal solution for applications demanding both mechanical performance and visual accessibility. The polycarbonate material offers exceptional impact resistance while maintaining transparency, making them perfect for electronic enclosures, display assemblies, and optical equipment where internal components need monitoring. The 1/4-20 UNC coarse threading with Class 2A fit ensures reliable engagement in plastic and soft materials, reducing the risk of stripping. The 82° countersink angle and flat head design create seamless surfaces in panels and assemblies, while the temperature resistance from -40° to 210°F ensures dimensional stability across various operating environments. These fully threaded screws are particularly valuable in industries requiring non-conductive, corrosion-resistant fasteners that comply with RoHS and REACH regulations.

Specification Summary & Compliance

This 1/4-20 UNC flat head screw features precise Class 2A thread fit according to Unified Thread Standard specifications, ensuring consistent dimensional accuracy. The 5/8" length and fully threaded design provide maximum engagement capability. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these screws suitable for regulated industrial and commercial applications. The standard 82° countersink angle matches common machining practices for flush installation requirements.
