Hexagonal Flange Nylon Lock Nut

主な特徴 
  • Allows for easy tightening/loosening with standard wrenches or sockets.
  • Available in standard (ISO, DIN, ANSI) and metric sizes (e.g., M4, M6, M8).
  • A wide, circular flange acts as an integrated washer, distributing clamping force evenly.

The fastening and opening of bolts and nuts adopts non-standard design, and the matching
non-standard tools are used to solve the opening and fastening problems. In general, other
wrenches cannot be inserted. In the appearance design of nuts and bolts, non-standard slotting,
opening or pentagonal, heptagonal, nine-corner or custom-made corresponding groove tools
have played a very good anti-theft effect

Hexagon Flange Nylon Locking Nuts (also called flanged nyloc nuts) are a type of self-locking fastener designed to prevent loosening under vibration and dynamic loads. They combine a hexagonal head, an integrated flange, and a nylon insert to ensure a secure, vibration-resistant connection without requiring additional washers or adhesives.


Key Features & Design

  1. Hexagonal Head (6-Sided)

    • Allows for easy tightening/loosening with standard wrenches or sockets.

    • Available in standard (ISO, DIN, ANSI) and metric sizes (e.g., M4, M6, M8).

  2. Flange Base

    • A wide, circular flange acts as an integrated washer, distributing clamping force evenly.

    • Protects the mounting surface from damage and improves grip.

    • Eliminates the need for a separate flat washer.

  3. Nylon Insert (Nyloc Feature)

    • nylon-6,6 ring embedded at the top of the nut deforms when threaded onto a bolt.

    • Creates friction resistance, preventing loosening from vibration.

    • Typically colored blue (sometimes white or natural).

    • Hexagonal Flange Nylon Lock Nut
  4. Material & Coatings

    • Nut Body: Carbon steel (Grade 8/10), stainless steel (A2/A4), or brass.

    • Surface Treatment: Zinc-plated (yellow/silver), black oxide, or galvanized for corrosion resistance.

  5. Thread Types

    • Metric (coarse/fine) or imperial (UNC/UNF).


Common Applications

  • 自動車 (engine mounts, suspension, wheel hubs)

  • Industrial machinery (conveyors, motors, pumps)

  • Electronics & appliances (preventing screw loosening)

  • Furniture & construction (where vibration is a concern)


Standards & Specifications

  • DIN 6923 (Flange nuts with nylon insert)

  • ISO 7040 (Prevailing torque type nylon insert nuts)

  • Hexagonal Flange Nylon Lock Nut
  • ASME B18.16.3M (Metric flange lock nuts)
