Description :

1. In today's smaller engines, tight work areas create great difficulties accessing nuts and bolts. The Uni-Grip extension's parallel flat sides are the only extension available that allows torque to be applied at any point along the shaft of the extension. The Uni-Grip extension weighs 10% less than traditional extensions. Finger tightening or loosening is the most efficient method of turning nuts and bolts. The Uni-Grip raised ridges provide up to 300% more torque enabling easier and faster tightening or loosening in almost all work applications. The raised ridges prevent Uni-Grip extensions from rolling off the work table or surface and reduce the common and time-consuming frustration of having to retrieve dropped or lost tools. The laser scale etched into flat sides of extension is perfect for quick measurements. Drive sizes can easily be identified by the pattern of the raised ridges.
2. 2 ridges=1/4"drive, 3 ridges=3/8"drive, 4 ridges=1/2"drive.
