Abstract
A method of forming a ratchet wheel adapted to be disposed in at least one end of the ratchet wrench for engaging an element to be turned, includes the step of providing a wheel blank having a generally hollow, cylindrical body formed with a radially projecting rib located midway between an upper hub portion and a lower hub portion, the upper hub portion being integrally formed with an upstanding lip having a diameter equal to or slightly smaller than the diameter of the upper hub portion. The method also includes the step of bending the lip inwardly to form a retention ring adapted to engage the upper surface of the element to be turned and prevent the element from slipping through the wheel of the ratchet wrench.
