Sorry this is not really a suitable topic for this forum, but I trust the people here and am sure someone will know the answer.
From time to time when working on precision things (high-speed spindles, microscopes, dial indicators, ...) I come across slotted screws with slots that are much too narrow for my standard screwdrivers. Often the standard screwdriver that fits the slot is 1/2 of the width of the screw, and sometimes less. Often these screws are torqued to the max, so without the right screwdriver, the head gets galled.
So....
-- What are these screw slots called? Is there a standard for them?
-- Do I need to grind down some spare screwdrivers, or can I purchase a set of the correct ones? Where? Are there both metric and imperial versions?
