A Hexagon Safety Wire Bolt is a specialized fastener designed to remain secure in high-vibration or high-torque environments, commonly used in aerospace, automotive, and industrial applications. Here’s a detailed description:

主要功能：

1. Hexagon Head – Features a standard six-sided (hex) head for easy tightening and loosening with a wrench or socket.

2. Safety Wire Holes – Includes pre-drilled holes (usually two) in the head or shank to allow safety wire (lock wire) to be threaded through, preventing loosening due to vibration.

3. 材質 – Typically made from high-strength materials like:

   • 不銹鋼 (e.g., AISI 304, 316) for corrosion resistance.

   • Alloy Steel (e.g., Grade 8, 10.9) for high tensile strength.

   • Titanium (e.g., Grade 5) for lightweight, high-strength applications.

4. 線路類型 – May have fine or coarse threads depending on the application (e.g., metric or SAE).

5. Surface Finish – Often coated with corrosion-resistant treatments like zinc plating, cadmium, or anodizing (for aluminum variants).

常見應用：

• Aircraft & Aerospace – Securing critical components like engine parts, landing gear, and control surfaces.

• Motorsports – Used in engines, exhaust systems, and suspension to prevent bolt failure.

• Military & Defense – Ensures reliability in firearms, vehicles, and machinery.

• 工業機械 – Prevents loosening in vibrating equipment like turbines and pumps.

Safety Wire Method:

• The bolt is tightened to the correct torque, and then a stainless steel wire is threaded through the holes and twisted tightly, connecting it to another secured bolt or fixed point. This prevents rotation in either direction.

優勢：

• 抗震性 – Prevents self-loosening in dynamic environments.

• 可靠性 – Provides a fail-safe mechanical lock where threadlockers may fail.

• Reusable – Unlike chemical adhesives, safety wire can be replaced.
