ABSTRACT:
A torque application device according to the present invention comprises a collar for engaging a fastener, a grip coupled to the collar such that a predetermined maximum torque can be applied to the collar to tighten the fastener, and a slip mechanism to prevent the likelihood that the maximum torque is exceeded. The device may further include an indicator (such as a visual, audible and/or tactile indicator) to indicate that the predetermined maximum torque has been applied.
