If you like that your job is done with the Efficere Tools Max Torque Premium Combination Wrench Set in standard metric sizes. This is the best tool set you need for home projects, garage work, auto repairs, truck services, plumbing, constructions, machinery, and a lot more, no matter if you are a homeowner, mechanic, contractor, or a shop owner, or just looking for a best value tool gift for someone you love. To ensure durability, all combination wrenches are made from high strength chrome vanadium steel with a corrosion-preventative mirror chrome finish to ensure durability. A specially designed “V”-shaped open end grips fasteners from all sides to deliver maximum torque while preventing fastener corners from rounding off. Additionally, these wrenches feature longer wrench bodies than most other brands to give you more leverage and make it easier to loosen stuck hex bolts and nuts. Featuring most common metric sizes from 8 mm to 22 mm, this spanner kit is organized and stored in a rack with a convenient handle grip, which is more convenient than a canvas roll-up pouch for carrying, storing in a toolbox, and hanging on a pegboard. We have wrench sizes from 8mm to 9mm, 10mm to 11mm, 12mm to 13mm, 14mm to 15mm, 16mm to 17mm, 18mm to 19mm, 20mm to 21mm, 22mm to 23mm.
