This set of combination spanners are designed to tighten/loosen nuts or hex head screws. This tool has a ratchet mechanism that maximises the contact area with the nut and allows a fast tightening, as the spanner does not have to be placed back every turn. The fixed profile allows a better insertion to the nut and a tight use. This ratchet profile has teeth that allow the spanner to be operated with a ratchet angle of 5 degrees, making it easy to work in confined areas due to small space. It also allows an increase in productivity without losing any time to place back the spanner. They are made from chrome-vanadium steel for high strength. The set has spanners in different sizes.
