Built to ASTM A194 Grade 2H and A563 Grade DH specifications, this heavy hex nut features a premium virgin PTFE Teflon coating, delivering ultra-low friction, exceptional non-stick performance, and robust chemical resistance for a wide range of industrial applications. Tailored for original equipment manufacturers (OEMs), industrial distributors, and engineering procurement contractors, our PTFE coated heavy hex nuts deliver consistent, long-lasting performance while reducing assembly labor and maintenance costs for your operations.
The virgin PTFE Teflon coating on our Heavy Hex Nut Teflon PTFE provides unparalleled resistance to a wide range of acids, alkalis, solvents, and corrosive media, outperforming standard plating options in harsh chemical and marine environments. This inert coating creates a permanent barrier against moisture and oxidation, eliminating rust and corrosion even in long-term outdoor or submerged applications.
With a dynamic friction coefficient as low as 0.04, our PTFE coated heavy hex nuts eliminate thread seizing and galling during installation and removal, making them ideal for applications requiring frequent disassembly and reassembly. This anti-seize property removes the need for additional thread lubricants, streamlining assembly processes and reducing maintenance time.
Forged from high-grade carbon and alloy steel, our PTFE Teflon Heavy Hex Nuts feature a thicker wall and wider bearing surface than standard hex nuts, delivering superior load distribution and clamping force for heavy structural and high-torque applications.
Every heavy hex nut undergoes automated electrostatic PTFE coating application to ensure consistent, uniform coverage across all surfaces, including internal threads, with no bare spots or build-up. Precision CNC machining guarantees strict adherence to dimensional tolerances, ensuring perfect compatibility with matching bolts and studs.
