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.

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.
