A ratcheting open-end wrench, comprising:
- a top jaw;
- a bottom jaw, the bottom jaw further comprising a cavity;
- a pin;
- an arm comprising a hole for the pin;
- and
- a spring;
- wherein:
- the top jaw and the bottom jaw together form a containing portion for receiving a fastener;
- the arm is located within the cavity of the bottom jaw, with the pin enabling the arm to rotate within the cavity;
- and
- the spring is located within the cavity of the bottom jaw, the spring connected on a first end to the arm and on a second end a floor of the cavity.
A ratcheting open-end wrench, comprising:
- a top jaw;
- a bottom jaw, the bottom jaw further comprising a cavity;
- an arm;
- and
- a spring;
- wherein:
- the top jaw and the bottom jaw together form a containing portion for receiving a fastener;
- the arm is located within the cavity of the bottom jaw;
- the spring is located within the cavity of the bottom jaw, the spring connected on a first end to the arm and on a second end a floor of the cavity;
- upon receiving the fastener into the containing portion the fastener makes contact with the arm, the arm preventing the fastener from moving further into the containing portion, such that the fastener is in a first position within the containing portion;
- when a user applies first torque to the ratcheting open-end wrench in a first direction, the fastener is turned in the first direction while in the first position, the first direction being one of clockwise or counterclockwise;
- and
- when the user applies second torque to the ratcheting open-end wrench in a second direction, a ratcheting action occurs, moving the fastener to a second position within the containing portion, the second direction being opposite to the first direction.
