New spanners are now available.
The spanners are cut from stainless steel, 2mm thick with close tolerances. I have improved the design in order to make the handling more useful.
In case you have tortured your nuts already with in-appropriate tools and have damaged the slots or diameters, light re-work either on the nuts or the spanners might be necessary. Pictures can be send
The prize of the set is EURO 42,50 plus freight.
