Wright Tool Company offers WrightGrip, an innovative, high-strength, anti-slip design on the manufacturer’s open-end style wrenches. The design is now available on Wright Tool open-end and combination wrenches in a range of metric sizes from 7mm to 24mm. The design incorporates a series of strategically placed teeth or grooves on the insides of the wrench’s two jaws. These teeth allow for a better seating of the wrench on a fastener. One fastener corner locks into the groove so the fastener won’t slip or twist out of the wrench under load.
