Teflon bolt
Teflon Bolt refers to high-strength fasteners made of polytetrafluoroethylene (PTFE) material or metal substrates (carbon steel / stainless steel / alloy steel) with a specially applied or sintered Teflon coating on the surface.
Teflon Bolt refers to high-strength fasteners made of polytetrafluoroethylene (PTFE) material or metal substrates (carbon steel / stainless steel / alloy steel) with a specially applied or sintered Teflon coating on the surface. It features extreme corrosion resistance, low friction self-lubrication, wide temperature stability, and insulation against adhesion. It is the preferred connection component for demanding environments such as those in the chemical, marine, food, and semiconductor industries.
Core Features & Advantages
◆ Extreme Corrosion Resistance Resistant to strong acids, strong alkalis, salt fog, organic solvents, and seawater corrosion. The salt fog test can last up to 1000 hours without rusting, and the lifespan is 3–5 times that of ordinary galvanized bolts. ◆ Low Friction & Self-lubricating The friction coefficient is as low as 0.04–0.1. The installation torque is reduced by 50%, and disassembly is not stuck or damaged. No maintenance required, no additional lubricants needed, and no pollution. ◆ Wide Temperature Stability Continuous use: -200℃ ～ +260℃; short-term peak: 300℃ It does not crack at low temperatures or soften at high temperatures, suitable for extreme conditions. ◆ Non-stick & Easy Cleaning The surface is smooth and does not adhere to materials, oil stains, or dust. It is suitable for food/pharmaceutical grade cleanliness and easy to clean. ◆ Excellent Electrical Insulation High insulation, non-conductive, no metal ion release, suitable for electronic/semiconductor/blast-proof scenarios. ◆ High Strength & Reliability The coating type retains the strength of the metal substrate (up to 8.8 grade / 120ksi), ensuring secure fastening, anti-loosening, and anti-vibration.
Common Specifications
◆ Material combination: Carbon steel + PTFE, 304/316 stainless steel + PTFE, A325 + PTFE, pure PTFE ◆ Strength grade: 4.8 grade, 8.8 grade, 10.9 grade (coated type); pure PTFE (medium-low strength) ◆ Surface color: Blue (common), black, yellow, original color ◆ Standards: ASTM F3125, ISO 4032, GB/T 5782.
Application Scope
◆ Chemical / Pharmaceutical: Reactors, pipelines, valves, acid-base equipment (corrosion prevention and anti-pollution) ◆ Ocean / Ships: Offshore platforms, marine equipment, coastal steel structures (salt fog resistance) ◆ Food / Beverages: Production line equipment, mixers, conveyors (cleanliness and anti-stick) ◆ Semiconductor / Electronics: Vacuum chambers, cleanroom equipment, insulation connectors ◆ High temperature / Low temperature: Heat treatment equipment, boilers, refrigeration units, LNG storage tanks ◆ Heavy industry: A325 Teflon bolts for steel structures, bridges, heavy-load equipment (corrosion prevention + high strength).
