This set includes 12 GEARWRENCH ratcheting combination wrenches in sizes: 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 mm This set has been the top SATA ratchet wrench set on the Polish market for 15 years. The eyelet connected to the GEARWRENCH ratchet has a small diameter, which allows for faster and more efficient work, especially in tight and hard-to-reach places where a traditional ratchet with a socket does not fit GEARWRENCH ratchet has a 5-degree pitch - a regular ratchet requires a 30-degree pitch or 6 times the surface area The gear mechanism in the ratchet is made of hardened steel The gear mechanism in the ring section has 72 teeth GEARWRENCH ratchets consist of only one rim that fits perfectly into the eyelet. This design makes the tools less prone to dirt accumulation in the ratchet mesh, which prolongs the life of the wrench Wrenches in sizes 10, 13 and 19 mm can be combined with a quick release adapter, easily obtaining a quick release ratchet for socket wrenches. The Surface Drive system in the ring part makes it easier to unscrew a bolt with a rounded (cropped) head SATA wrenches are made of high-quality chrome vanadium (Cr-V) steel The wrenches are protected against corrosion Thanks to the polished surface, the wrenches are easy to keep clean The keys are manufactured to the highest standards so they meet the expectations of users around the world The dimensions of the SATA wrenches comply with the American ASIN standard and the German DIN standard This set includes 12 GEARWRENCH ratcheting combination wrenches in sizes: 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 mm This set has been the top SATA ratchet wrench set on the Polish market for 15 years.
