Proto Industrial Tools has introduced a new line of chrome, reversible ratcheting combination wrenches with spline box ends.
The wrenches feature a new open-end configuration that allows up to 13 degrees of additional swing, according to Proto. The offering includes 38 fractional and metric sizes, as well as four wrench sets.
Proto says the new wrench pattern features a patented I-beam design that removes material weight while offering an increased bearing surface to help improve comfort and reduce hand fatigue. The wrenches can be used on spline, four-point, six-point, 12-point and Torx fasteners, the company adds.
