Ratchet Mechanism:

  • The ratchet mechanism is an essential part of a socket wrench that allows for both clockwise and counterclockwise rotation without the need to remove and reposition the socket.
  • It consists of a ratchet gear and a pawl. The gear has teeth that engage with the pawl, which prevents backward movement when torque is applied in the desired direction.

Switch or Lever:

  • A switch or lever is typically located on the handle of the socket wrench and is used to control the direction of rotation.
  • By flipping the switch or moving the lever, you can easily change between clockwise and counterclockwise rotation.

Extension Bar (optional):

  • An extension bar is an optional accessory that can be added between the socket and the handle.
  • The extension bar extends the reach of the socket wrench, allowing you to access bolts or nuts in hard-to-reach areas.

Understanding the different components of a socket wrench is crucial to using it effectively for various tasks. By knowing how each component functions, you will be able to assemble and use the socket wrench correctly for your specific needs.

Attach the Handle to the Socket
