A Teflon (PTFE/Xylan) coated nut is a threaded metal fastener finished with a synthetic fluoropolymer layer. It offers extreme corrosion resistance, a very low friction coefficient (0.06–0.08), and protection against galling, making it ideal for harsh industrial, marine, and petrochemical environments.

Major Benefits

• Corrosion Protection: Resists salt spray, moisture, and aggressive chemical exposure.

• No Seizing: Prevents cold-welding or galling of threads during tightening and loosening.

• Easy Removal: Allows fasteners to be unbolted easily after years of exposure without needing a torch or cutting.

• Consistent Tension: Ensures uniform load distribution when torquing.
