Tackle a range of projects and a variety of fastener types with the STEELMAN 60712 6-Piece Universal Folding Nut Driver Set. This compact, pocket-sized tool contains nut drivers for 6 of the most commonly encountered SAE and metric fastener sizes in a universal spline style that fits on 4-point / square, 6-point / hex, 12-point, star, spline, and even mostly rounded fastener heads. Each driver features a deep shaft that allows it to reach nuts on extended bolts that regular nut drivers can't. The folding design, in addition to making this tool set easy to carry and store, provides better access to tight areas as the tool can be adjusted to better fit the available space. Includes nut drivers in 3/16-inch, 1/4-inch, 5/16-inch, 11/32-inch, 3/8-inch, and 7/16-inch (5mm, 6mm, 7mm, 8mm, 10mm, and 12mm). Backed by a limited lifetime warranty.
