Professional Applications & Engineering Value
This nylon plastic pan head screw with 3/8"-16 UNC coarse threading addresses critical needs in electrical enclosures, automotive components, and marine equipment where metal fasteners risk galvanic corrosion or electrical shorts. The rounded pan head design distributes clamping force evenly, reducing surface damage on softer materials. Its Phillips drive ensures straightforward installation with standard tools, while the fully threaded shank enhances pull-out resistance in plastic or composite substrates. Engineered for temperature resistance from -40°F to 185°F, it maintains integrity in outdoor or thermally cyclic environments, making it a reliable choice for HVAC, electronics, and industrial machinery assemblies requiring non-conductive, lightweight fastening solutions.
Specification Summary & Compliance
This screw features Class 2A thread fit per UNC standards, ensuring consistent engagement and interchangeability. Manufacturing adheres to ASME B18.6.3 specifications for dimensional accuracy, including 3/4" head diameter and 1" length. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe use in global markets.
