Cage Nuts
Cage Nuts are square or rectangular nuts enclosed in a spring steel cage, designed to provide secure fastening in panel mounting, server racks, telecommunications, and industrial enclosures. The flexible cage allows easy insertion into pre-punched holes, enabling a floating nut that accommodates misalignment and reduces installation stress.
At Rajal Industries, we manufacture precision-engineered Cage Nuts conforming to DIN and general fastening standards, ensuring high load-bearing capacity, easy installation, and durable performance.
