Thumb screws can be used in a wide range of tasks and assemblies. Their main use is for fastening down panels, wiring, lids, safety covers, battery compartments, and any other part or component that might need to be removed and reinstalled frequently.
How Type A thumb screws are measured: from under the shoulder to the tip. Type B: these do not have a shoulder and are also referred to as Type P thumb screws. Shoulderless thumb screws are often used as compression fasteners where the tip contacts the mating surface, similar to a set screw.
Usually, thumb screw sizes—listed as whole numbers and fractional inches—range from #6 to 3/8" in diameter; 1/2" may also be available. Lengths start at 1/4" and go up to about 6". Only larger sizes are available in long lengths.
