Custom lock nuts

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

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

Custom lock nuts are specialized fasteners designed to resist loosening under vibration, torque, or dynamic loads.  ensuring secure and reliable fastening in critical environments.

Key Characteristics:

1. Locking Mechanism – Utilizes various anti-loosening features such as:

   • Nylon inserts (elastic deformation for friction-based resistance).

   • Deformed or elliptical threads (creates interference fit).

   • Metal locking rings or teeth (serrated edges or secondary locking collars).

   • Chemical adhesives (thread-locking patches for permanent retention).

2. Material & Finish Customization –

   • Materials: Stainless steel (304/316), alloy steel (grade 8/10), brass, titanium, or high-temperature alloys.

   • Coatings: Zinc plating, black oxide, Dacromet, nickel, or PTFE for corrosion/chemical resistance.

3. Dimensional Adaptability –

   • Custom thread sizes (metric, UNC, UNF, or proprietary pitches).

   • Modified shapes (flanged, knurled, low-profile, or extended grip lengths).

4. Performance Enhancements –

   • High-temperature resistance (for engines/exhaust systems).

   • Custom lock nuts

Advantages of Customization:

• Enhanced reliability for mission-critical assemblies.

• Reduced maintenance by preventing spontaneous loosening.

Custom lock nuts are ideal when standard options fail to meet unique operational demands. Would you like guidance on selecting a specific type based on your use case?
