With reference to the Q-nuts ratchet spanner it has the following advantages against the existing spanners/nuts.
· The Q-Nuts spanner requires very limited space around the nut in order to be able to slip the tool on the nut.
· It requires only a very small turning angle to takes advantage of it’s ratchet function. In most cases 5 degrees is possibly.
· The assembly time to install tubes or pipes reduce rather dramatically.
· The mating capnuts are at the same price level of conventional hexagon capnuts.
· Consequently it allow designers to develop more compact manifolds, in order to safe material.
· The Q-nuts ratchet spanner is relatively cheap due to a very limited number of parts.
· The fact that the ring section of the Q-nut spanner enclose more than 50% of the nut allows the user to let the tool hang onto the nut without it is dropping.
· The open ring concept of the tool enables the user to slip it over a hose or a tube and follow the hose or tube down to the nut, even under circumstances where the nut is in a position that it is not or hardly visible
· It is almost impossible that the tool slips off the nut unintentionally during the tightening of the nut.
