GearWrench Original ratcheting wrenches combine the speed of a ratchet with the access and control of a wrench. They offer the ease of 5 degrees of movement to turn fasteners, versus 30 degrees on standard combination wrenches. The small ratcheting box end head design enables access to tight spots where a ratchet won't fit. The open end allows for easier access on tough to reach spots, making jobs go faster and easier. This set is a great addition to any mechanic tools collection. Includes: Sizes: 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 24mm.
