Professional Applications & Engineering Value

This PTFE plastic flat head screw is engineered to solve critical challenges in demanding industrial applications where metal fasteners fail. Its high-temperature resistance makes it indispensable in thermal processing equipment, aerospace components, and automotive systems exposed to extreme heat cycles. The chemical inertness of PTFE prevents degradation in aggressive environments like chemical plants, semiconductor manufacturing, and food processing lines, eliminating corrosion and contamination risks. With 10-32 UNF fine threading and Class 2A fit, it delivers vibration-resistant, precise fastening in plastic, composite, or soft metal assemblies. The slotted flat head design with standard countersink ensures seamless integration into panels and enclosures, providing a secure, low-profile finish that withstands thermal expansion and chemical exposure without loosening.

Specification Summary & Compliance

This screw adheres to ASME B18.6.3 specifications for dimensional accuracy and performance. Threading conforms to UNF 10-32 with Class 2A tolerance for consistent fit. The 82° countersink angle and flat head profile meet standard industrial requirements. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated markets.
