Thumb Screws at Empire Bolt & Screw

Thumb Screws are designed to be tightened and loosened with finger pressure and are typically used where frequent adjustment or disassembly is required. They are fully threaded.

Multiple Types of Thumb Screws

Type A (also known as Type S) has a shoulder; Type B (also known as Type P) does not have a shoulder.  The shoulder adds a bearing surface, which allows Type A Thumb Screws to be tightened against the mating surface.
