Micro-Mark offers a selection of hard-to-find miniature taps, dies and bits for a wide variety of projects, including model building, clock-making, instrument repair and fabrication, watches, machining and machine work, component assembly, and more. Clearance Drills are bits of the correct size for drilling a hole just large enough for the shank of a corresponding-size screw to pass through without touching, such as the hole in a washer. The holes made by clearance drills are not to be tapped.

See the chart below for Tap, Die and Drill size reference. For additional information, an explanation of Taps and Dies follows the chart.

Tap and Die sizes follow the same naming standards as machine screws; shank size - threads per inch. For example, a cylinder threaded with a 0-56 tap would hold a size 0, 56 thread-per-inch screw.
