What is a "thumb screw"?
A thumb screw is a type of screw that has a large, textured head, designed to be tightened or loosened by hand, without the need for tools. The head is usually wide enough for a person to grip and turn with their fingers, making it easy to adjust or remove. Thumb screws are commonly used in situations where frequent adjustments are needed, such as in electronics, machinery, or equipment that needs to be opened or closed often. They provide a quick and convenient way to fasten or unfasten parts.
Examples
