Is it possible to obtain from any source a Tri-Wing Screwdriver having a shaft length of 80-100mm, max. shaft diameter 5-6mm, and tip size 4mm? Neither of the two local hardware stores stock anything other than tri-wing bits for Interchangeable bit screwdrivers, but these are too large in diameter to go into the screw holes in a plastics case. E-Bay and other sites list quite a few tri-wing drivers, but only give bit sizes as TR10, TR100, etc., which means nothing to me.
