Description: |
| The movable jaw of the nut wrench adjusts by a screw rod extending through the end of the handle. The outer surface of the movable jaw also serves as the adjustable jaw of the pipe wrench. The frame holding the hook jaw of the pipe wrench can be removed from the main shank of the wrench. Pins extending from the side of the movable jaw and pipe wrench frame are intended to serve as pin spanners to hold flanges with bolt holes. |
