Description: |
| The wrench has a spring-loaded hook jaw similar to many self-adjusting pipe wrenches. A set screw acts as a size adjustment limiting the closure of the jaws. The specifications describe it as a nut wrench. It has a screwdriver on the end of the handle, and a "hang hole" in the handle is also specified. |
