I screwed these countersunk rare-earth magnets to the back of the cabinet door where I keep my cordless screwdriver. They hold my most often used screwdriver bits at the ready. The magnets have about a 1/8″ projection, which makes grabbing the bits easy. If you adopt this trick for your shop, be sure to gently hand-drive the screws, since rare-earth magnets are brittle.
