ワンウェイバレルナット

主な特徴
  • Barrel Shape – Cylindrical design with internal or external threading, resembling a barrel.
  • 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.
  • 耐振動性 – Prevents self-loosening in high-vibration environments (e.g., automotive, aerospace, machinery).

one-way barrel nutとしても知られている。 one-way clutch barrel nut または 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.

主な特徴
  1. Barrel Shape – Cylindrical design with internal or external threading, resembling a barrel.

  2. ワンウェイバレルナット

  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. 耐振動性 – Prevents self-loosening in high-vibration environments (e.g., automotive, aerospace, machinery).

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

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

一般的な用途:
  • Automotive & Aerospace – Securing critical components subject to vibration.

  • 産業機械 – 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.
