Abstract
A ratcheting wrench includes a handle, a head extending from an end of the handle and having a hole communicated with a compartment in the end of the handle, a drive member rotatably mounted in the hole of the head, and a ratcheting mechanism. The drive member includes an inner periphery for securely holding a fastener-driving member, allowing joint rotation when the drive member is turned. The drive member further includes a flange formed on an end of an outer periphery thereof and located outside the head for manual rotation of the drive member. The ratcheting mechanism is mounted in the compartment of the handle and engaged with the teeth of the drive member, allowing the handle to selectively move in a ratcheting direction for tightening/loosening a fastener and in a free turning direction reverse to the ratcheting direction in which the fastener is not turned.
