A thumb screw has a specially designed head that makes it easy to turn with one hand and ideal for use on parts that are frequently moved such as an access panel. The heads are winged, knurled or vertically tall and flat to provide an easy grip.
Thumb screws offer a hand-adjustment feature, which allows for simple action to fasten, tighten, loosen, or remove the screws. The main benefit is that no tools are needed, so assembly teams and end-user consumers can adjust the screws with thumb and forefinger alone.
