Professional Applications & Engineering Value
This 1/4-20 UNC PTFE plastic screw delivers critical performance advantages in demanding industrial settings where metal fasteners fail. The white PTFE material provides inherent corrosion resistance against chemicals, solvents, and aggressive media, eliminating galvanic corrosion concerns in mixed-material assemblies. The fully threaded design with right-hand coarse threading ensures maximum engagement in plastic, composite, or soft metal substrates, while the rounded head style minimizes stress concentration and surface damage. Engineered for extreme temperature applications from cryogenic to high-heat environments, these slotted drive screws maintain dimensional stability where thermal expansion would compromise ordinary plastic fasteners, making them ideal for chemical processing, food equipment, and electrical enclosures requiring non-conductive, non-magnetic properties.
Specification Summary & Compliance
This rounded head screw features precise 1/4"-20 UNC coarse threads with Class 2A fit tolerance for consistent performance. The fastener is fully threaded along its 1" length with standard right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial applications worldwide.
