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:
-
Hexagon Head – Features a standard six-sided (hex) head for easy tightening and loosening with a wrench or socket.
-
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.
-
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.
-
-
線路類型 – May have fine or coarse threads depending on the application (e.g., metric or SAE).
-
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.
