Professional Applications & Engineering Value

These clear polycarbonate flat head screws deliver exceptional value in applications where both visibility and mechanical performance are critical. The M4 metric coarse threading with 0.7mm pitch ensures rapid installation while maintaining secure fastening in plastic and lightweight metal assemblies. The polycarbonate material offers excellent impact resistance and maintains dimensional stability across the specified temperature range, making these slotted drive screws ideal for electronic enclosures, optical devices, and laboratory equipment where non-conductive, corrosion-resistant fasteners are essential. The combination of Class 6g thread fit and fully threaded design provides consistent clamping force distribution, preventing loosening in vibration-prone environments while the transparent appearance maintains aesthetic integrity in visible applications.

Specification Summary & Compliance
