Features:
-The genius of attacking a bolt/nut on all 6 flat sides removes the stress and strain on the corners of the bolt.
-This coupled with the superior gripping action of the jaws, allows the user to complete their work without the wrench slipping off and damaging the bolt.
-The design multiplies your hand's gripping force, so you can more easily tighten/loosen bolts.
-You can develop ratchet-like speed by fully turning the wrench, release the grip while still on the bolt, reposition wrench, tighten grip-repeat until finished.
