Teflon (PTFE) Anti-Corrosion Coated L7M Alloy Steel Hex Head Bolt And Nut Assembly

This fully threaded hex head bolt assembly is produced from L7M alloy steel and finished with a Teflon (PTFE) anti-corrosion coating, delivering high strength together with outstanding chemical and corrosion resistance for low-temperature and offshore service.

Core Selling Points

  • Teflon (PTFE) Anti-Corrosion Coating — a low-friction, non-stick fluoropolymer barrier that resists acids, alkalis, salts and moisture far better than conventional zinc plating.
  • L7M Alloy Steel Grade — Charpy V-Notch impact tested at –73 °C (–100 °F) per ASTM A320 Grade L7M, with modified chemistry for improved notch toughness in cryogenic service.
  • Anti-Galling and Easy Removal — The PTFE low-friction surface reduces thread galling and lowers breakout torque after extended service in corrosive environments.
  • Supplied as a Matched Assembly — Bolts, studs and nuts share the same grade (ASTM A320 L7M bolts with ASTM A194 Grade 7M nuts), the same PTFE coating and the same blue finish for full assembly consistency.
  • Visible Quality Traceability — Each fastener is stamped "L7M" on the end face; the uniform blue coating provides instant on-site identification against mixed-grade installations.

Key Features

  • Fully threaded shank for maximum grip range and fine adjustment.
  • Standard hexagon head, wrench-driven, suitable for high-torque bolted joints.
  • Supplied complete with a matching hex nut for immediate installation.
