🔩 Cage Nut – Clip-in Captive Nut for Sheet Metal & Server Racks | Neo Fasteners
Cage Nuts, also known as Captive Nuts or Clip Nuts, consist of a square nut enclosed in a spring steel cage that wraps around it. The cage has two wings or tabs that allow the nut to be clipped into square holes—commonly in server racks, enclosures, and sheet metal panels—without needing threads in the base material.
At Neo Fasteners, we supply a wide range of Cage Nuts in metric and inch thread sizes, available in Stainless Steel, Zinc-Plated Steel, Black Phosphate, Brass, and Nylon, with matching screws and washers if needed.

- Spring steel cage holds nut securely in square holes
