Get your job done with Efficere Tools 15-Piece Max Torque Premium Combination Wrench Set in standard metric sizes. This is the perfect wrench sets you need for home projects, garage works, auto repairs, truck services, plumbing, constructions, machinery and a lot more, no matter you are a homeowner, DIYer, mechanics, contractor, a shop owner, or just look for a best value tool gift for men. All the wrenches are constructed from high strength chrome vanadium steel with corrosion preventative mirror chrome finish to ensure durability and all exceed ANSI B107.6 quality standards. They feature with the specially engineered “V”-shape open end that grips four sides of fasteners to deliver the maximum torque and prevent fastener corners from rounding off. These wrenches also come with a longer wrench body than most other brands to provide more leverage, and make your job easier to loosen stuck allen hex bolt and nut. The 12-point box end with 15-degree offset doubles the access angle than 6-point, and creates clearance for hands or obstructions in tight work spaces. Including most common metric sizes from 8 mm to 22 mm, this combo spanner kit is stored and organized in a durable rack with a space-saving foldable handle grip, which is more convenient than a canvas roll up pouch for carrying, storing in tool box and hanging on pegboard. Wrench sizes include: 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm.
