12-point locking nut black zinc

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

A 12-point locking nut black zinc is a high-performance fastener designed for secure, vibration-resistant applications where corrosion protection and precise torque application are critical. The 12-point (dodecagonal) design allows for 30° tool engagement, making it ideal for tight spaces, while the black zinc plating provides enhanced durability and a sleek, non-reflective finish.

Key Features:

1. 12-Point Design

• 30° tool engagement (vs. 60° for standard hex nuts) for better accessibility in confined areas.

• Compatible with 12-point sockets, wrenches, and torque tools (common in aerospace, automotive, and military applications).

2. Black Zinc Coating

• Corrosion-resistant – Protects against rust and oxidation in harsh environments.

• Aesthetic & Low-Reflectivity – Ideal for applications requiring a discreet or non-glare finish.

• Improved Lubricity – Reduces friction during installation, aiding in precise torque application.

3. Locking Mechanism

• Prevailing torque (deformed threads or nylon insert) to resist loosening under vibration.

• Alternative versions may include metal locking collars, serrated faces, or secondary retention features.

Summary:

The 12-point locking nut black zinc combines high-strength fastening, vibration resistance, and corrosion protection in a compact, tool-friendly design. Ideal for critical applications where reliability and environmental durability are paramount.
