A fourteen piece set of ultra thin, double open ended spanners with ratcheting action profile. This profile allows the spanner to be quickly repositioned on the nut or bolt without having to completely remove the spanner from the fastener. This, and the spanner being ultra thin, make it easier to operate when space is restricted. This set contains 10 metric sized spanners and 4 SAE.     Ratcheting profile allows the fastener to be turned without taking the spanner off. Sizes: 6 to 24mm and 1/4 to 3/4". 65Mn hardened carbon steel. Chrome plated and mirror finished.
