Description:
The ratchet pawl also holds the head in the handle. The pawl can be withdrawn sufficiently to allow the head to be removed and replaced. The head has an opening extending to the outside edge to allow the head to be slid onto a bolt head or nut in a fashion similar to an open end wrench.
