ABSTRACT:
A tool for use in tightening or removing a fastener that requires greater torque than the user can generate through application of hand force on the handle of the tool with the handle of the tool having sufficient length for a user to grasp in the user's hand as the user tightens or removes a fastener. The handle of the tool having a head with jaws for engaging a fastener to tighten or remove the fastener and a second end on the opposite end of the handle having a square opening to receive a drive mechanism to permit the user to increase the torque on a fastener by providing a longer lever to thereby permit the user to increase the torque on the fastener without the user having to increase the hand force.
