PTFE (Polytetrafluoroethylene) Coated Nuts are fasteners coated with a layer of PTFE, a versatile fluoropolymer known for its exceptional properties. This coating offers remarkable corrosion resistance, even in harsh environments, and provides excellent lubricity, reducing friction during assembly and disassembly. PTFE-coated nuts are widely used in chemical processing, marine engineering, and automotive manufacturing industries, where reliability and longevity are crucial. The PTFE coating also prevents galling and seizing, ensuring smooth operation and prolonged lifespan of the fasteners in various applications.

At Sumit Impex, we prioritize quality, as demonstrated by the comprehensive documentation accompanying our PTFE Coated Nuts. Our package includes commercial invoices, packaging lists, fumigation certificates, heat treatment charts, and approved lab test reports.
