Professional Applications & Engineering Value

This PTFE plastic slotted pan head 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 moisture while maintaining dimensional stability across an extreme temperature range from -350°F to 500°F. The UNC coarse thread pattern with Class 2A fit ensures reliable engagement in soft materials and plastics without stripping, while the slotted pan head design offers straightforward installation in confined spaces. Ideal for chemical processing equipment, food machinery, electrical enclosures, and laboratory instruments where non-conductive, non-contaminating fasteners are essential for system integrity and operational safety.

Specification Summary & Compliance

This 1/4"-20 x 1" plastic fastener features precise UNC coarse threads with Class 2A thread fit tolerance for consistent engagement. Manufactured to ASME B18.6.3 specifications for dimensional accuracy and performance reliability. Fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. The fully threaded design with right-hand thread direction provides maximum fastening versatility across industrial applications.
