What is a Thumb Screw?

Thumb Screw Description

Thumb screws are threaded fasteners with textured heads that allow them to be fastened and unfastened by hand. Thumb screws are typically used on low stress applications that require easy access. For example, thumb screws are often used to secure the side panel of desktop computer enclosures.  Thumb screws are manufactured in many different lengths, diameters, thread sizes, and materials. Thumb screw materials include aluminum, brass, nylon, steel, and stainless steel.
