Professional Applications & Engineering Value

Engineered for demanding industrial environments, these PTFE plastic screws with 1/4"-20 UNC coarse threading solve critical challenges in chemical processing, food manufacturing, and high-temperature applications. The white PTFE material maintains dimensional stability while providing excellent resistance to chemicals, solvents, and extreme thermal cycling. The flat head design with 82° countersink creates seamless surfaces that prevent contamination buildup and facilitate easy cleaning. As fully threaded fasteners with Class 2A thread fit, they ensure consistent clamping force and vibration resistance in assemblies requiring non-conductive, non-corrosive solutions where metal fasteners would fail.

Specification Summary & Compliance

This flat head slotted screw features precise 1/4"-20 UNC coarse threads with Class 2A thread fit per ASME B18.6.3 specifications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The inch-system measurements guarantee dimensional accuracy with standard 82° countersink angle for proper seating in matched components.
