Te-Co T-Slot Nuts - English Sizes

T-slot nuts

T-slot nuts are often used on milling machines and other types of machine tools to secure fixtures, workpieces, and other components to the machine's table or bed.

The T-shaped profile of the nut fits into a corresponding T-slot in the table or bed, and the nut can be tightened

This allows for precise positioning and secure attachment of the workpiece or fixture, which is important for accurate machining operations.

T-slot nuts are also used on other types of machine tools, such as lathes, grinders, and 3D printers, as well as in a variety of other applications where the T-slot table or bed is used as a support or framing element.
