The M-BDHK-1 Balldriver® Allen Wrench Set includes seven metric wrenches and a solid aluminum holder. Sizes include: 1.5, 2, 2.5, 3, 4, & (2) 5 mm. Balldriver® Allen Wrenches are made from high torque steel with a hardened ball tip for angled entry up to 25°. They are much faster to use than standard Allen wrenches and make tightening hard to reach screws simple. Balldrivers have a screwdriver handle for comfort and speed. The balldriver holder is made from a solid block of aluminum so it won’t tip over when removing or inserting a wrench. Individually marked holes make selection of the correct wrench easier. No more searching for that lost wrench—simply pick up the entire set and bring it to your work area.
