A 12-point 螺帽 with groove is a specialized fastener combining a 12-point (dodecagonal) head with integral slots for enhanced locking functionality. This design provides multiple engagement surfaces for torque application while incorporating a positive locking mechanism to prevent loosening under vibration or dynamic loads.

主要功能：

1. 12-Point Head Design

   • Allows 30-degree tool engagement (vs. 60° for hex nuts), ideal for tight spaces.

   • Compatible with standard 12-point sockets (common in aerospace and high-performance applications).

2. Integrated Slots (Locking Feature)

   • Slots accommodate lock wire (safety wire), cotter pins, or retaining clips for fail-safe security.

   • Prevents rotation due to vibration, making it ideal for critical assemblies.

3. Materials & Finishes

   • 材料： Stainless steel (A2/A4), alloy steel (Grade 8, 10), titanium, or corrosion-resistant alloys.

   • Coatings: Zinc plating, black oxide, cadmium (for aerospace), or PTFE for lubrication.

Advantages vs. Standard Nuts:

 Superior Locking – Slots ensure mechanical retention (unlike nylon inserts).
 Reusable – Unlike chemical threadlockers, slotted nuts can be reused after inspection.

Summary:

A 12-point nut with groove is a high-security, vibration-resistant fastener used in mission-critical applications where standard nuts would fail. Its 12-point head allows efficient torque application, while the integrated slots ensure absolute locking via wire or pins.
