Martin Tools 55mm Combo Wrench

Combination wrenches are manufactured from steel bar. These wrenches are available in fractional sizes from ?" through 2-1/2" and in Metric sizes from 6mm through 60mm. They come in a Chrome or Industrial Black finish. These are general purpose wrenches designed for a wide variety of work. This wrench combines a 15 degree angled slotted opening at one end and a 15 degree offset 12 point box opening at the other end for improved gripping. The openings are of the same size. Use the slotted opening generally for quick run down. Use the box end for final tightening and/or to avoid obstructions. All 12 point box openings through 2" fractional size are "Lobular" design which reduces the risk of fastener rounding, provides a better grip on worn fasteners and allows more torque to be applied to the fastener.
