Explore PTFE screws for assemblies exposed to chemicals or requiring an electrically insulating fastener. PTFE (polytetrafluoroethylene) is a fluoropolymer known for its broad chemical resistance and exceptionally low friction.
Key properties
-
Chemical resistance: Suits contact with many aggressive substances, subject to compatibility checks.
-
Electrical insulation: Helps prevent an unwanted conductive path.
-
Low friction: Gives PTFE screws their characteristic smooth surface.
-
Temperature resistance: Provides an option for applications involving heat, within the product’s stated limits.
PTFE screws are used in chemical-processing equipment, laboratory instruments and electrical assemblies. Their material properties are useful where the fastener may be exposed to the same conditions as the surrounding components.
Choose a screw by thread size, length and head style, then check its product specification against your operating conditions. PTFE can gradually deform under sustained load, so pay particular attention to tightening guidance and the clamping force your assembly requires.
