Cage Nut

Cage Nuts are specialized nuts enclosed in a spring steel cage, designed to snap into square holes in sheet metal or rack panels. They provide strong machine threads in equipment racks where welding or tapping is not possible. Manufactured to ASTM and DIN standards, they are available in square, round, and clip-in designs. Their replaceable design makes them highly versatile for IT racks, enclosures, and structural framing systems. They are widely used in data centers, telecom racks, server cabinets, automotive, and industrial enclosures.
