A one-way barrel nut，也稱為 one-way clutch barrel nut 或 anti-rotation barrel nut, is a specialized fastener designed to allow tightening in one direction while preventing loosening due to vibration or rotation in the opposite direction.

主要功能：

1. 桶狀 – Cylindrical design with internal or external threading, resembling a barrel.

2. One-way barrel nut

3. One-Way Mechanism – Contains a locking feature (such as a clutch, cam, or ratchet system) that permits rotation in the tightening direction but resists counter-rotation.

4. 抗震性 – Prevents self-loosening in high-vibration environments (e.g., automotive, aerospace, machinery).

5. 材質 – Typically made from hardened steel, stainless steel, or other high-strength alloys for durability.

6. 安裝 – Requires a specific torque or tool (e.g., spanner, socket) for installation; some versions may be hand-tightenable.

常見應用：

• Automotive & Aerospace – Securing critical components subject to vibration.

• 工業機械 – Fastening rotating parts where back-off is a risk.

• Consumer Electronics – Preventing screws from loosening in devices.

• Bicycles & Sporting Equipment – Used in high-stress, dynamic assemblies.

This type of nut is ideal for applications where traditional lock washers or thread-locking adhesives may not provide sufficient resistance to vibration-induced loosening.
