Description: |
The geometry of the swinging loop ends and the lobes on the handle extending into those loops are such that the wrench will bear on the sides of hexagon nuts and bolt heads. The design is intended to provide a type of ratchet action, and to lessen the chance of damaging the corners of hexagon nuts and bolts.
Produced as the VIMCO wrench, with initial sales and promotion from an Omaha, NE address.
Compare this to J.E. Meredith's patent no. 651,574. |
