The SAE/MM Combination and Stubby Wrench Set includes a total of 38-pieces. This set comes with the SAE/MM Combination Wrench Set (24-Piece), the Stubby SAE Combination Wrench Set (7-Piece), and the Stubby MM Combination Wrench Set (7-Piece). Husky combination wrenches are forged from Chrome Alloy steel for outstanding durability and strength for a lifetime of use. Each wrench as an open-end for access to fasteners in tight spaces and a 12-point box-end to get a secure grip on fasteners when added torque is needed. The shorter beam design on the stubby wrenches provide access to hard-to-reach fasteners in locations where a standard length wrench just won't fit. No toolbox or workshop of the DIYer or professional would be complete without a this set of combination wrenches from Husky.
