The Matco Tools Dual-Offset Combination Wrenches have a twin-angle design that allows access to tight and narrow spaces and an ability to provide increased leverage with an open end indexed to 30 degrees and a box end at 15 degrees. The non-slip open-end design loosens and tightens fasteners rounded up to 70 percent. Matco's Non-Slip Sockets offer a design that protects and works on six-point, 12-point, TORX and even 70-percent rounded nuts and fasteners. The wrenches can be found in standard or metric sets, and the sockets are available in 1/4" and 3/8" drive options in a range of metric sizes and lengths.
