This simply makes your life easier and tool box less crowded. The Jonnesway Super Tech design reduces the variations of wrenches you need and unlike other all in one systems, this drives in the flats (flanks) of the nuts as opposed to corners.
Manufactured from high quality materials including Chrome Vanadium Steel (Cr-V4), Molybdenum and Tungsten, the Jonnesway SUPER TECH ONE DRIVE technology accommodates 7 different types of nuts and bolts. Contact on nuts and bolts is evenly distributed across flat surfaces instead of the corners and points, the way other all-in-one drive systems operate. This protects the nuts and prevents rounding.
The SUPER TECH system fits Metric 6pt. Metric 12pt, SAE 6pt, SAE 12PT, E-TORX, Spline, Square & 50% rounded off nuts bolts. This eliminates the need to carry multiple tool sets.
These combination wrenches come with a 15 degree offset design with a Satin finish.
