A couple of sizes of split-blade screw starters will be handy.
I’ve learned to avoid magnetic screwdrivers for working on sewing machines. While a magnetized driver sounds like a good idea, I’ve dropped more screws using one than not. You can’t turn the magnetism on or off, and the blade tries to stick to everything it’s not supposed to stick to, knocking the screw loose.
If a screw must be held to the driver tip to be inserted, use a split-blade screw starter. Most sewing machine screws are either flat-blade screws, or combination flat-blade/Phillips head screws.
