Wrench Adapters

GP® 930QC Hole Quick Change Adapter, 1/4 in Drive, 1.38 in OAL

Proto® torque adapters are designed with a center-to-center dimension of 2 in. This means that the distance from the center of the square drive of the mating torque wrench to the center of the fasteners is exactly 2 in. This constant dimension serves to simplify the process of calculating the torque applied.
