Hexagonal Flange Nylon Lock Nut

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)

   • A 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)
