Description: |
| The wrench opening is intended to firmly grip hexagonal nuts. It is slid onto a corresponding nut, and then rotates into a "binding" position to firmly grasp the nut. This was designed for hexagonal nuts on railroad fish plate bolts. Track maintenance wrenches similar to this design were produced and used, so the idea was workable. |
