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.

主要功能：

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.
