A seven 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. Ratcheting profile allows the fastener to be turned without taking the spanner off.
