A speed wrench and complimentary hand grip is provided. The wrench includes a casing which mounts a standard drive mechanism which has a drive member axially projecting from the casing in order to engage a work piece. The wrench has an added feature in the form of a drive head rigidly attached to the casing axially thereof on a side opposite the drive member. The drive head has parallel exterior sides and an interior axial cavity. Thus, the wrench may be torqued by both a normal auxillary wrench having a wrench head that engages the exterior sides by a normal lug wrench which has a drive lug that may mateably engage the cavity. The complimentary handle is in the form of a shell that nestably receives the wrench. The handle has an axial opening sized to receive the drive head whereby rotation of the handle rotates the wrench. The opening also allows access to the drive head cavity while the handle and wrench are nested.
