Cage nuts combine the classic elastic properties of fasteners used for assembly with the strength of multi-threaded steel nuts. Cage nuts are designed to be used in any kind of assembly including blind assemblies and are particularly common in equipment racks. They can be fastened within their housing using bolts and subjected to considerable tightening torque or axial forces. No special tools or specialized fitters are required to mount these nuts. The use of cage nuts allows for a great reduction in assembly time, as costly operations such as tapping, welding or riveting can be avoided. Due to the fact that the nuts are slightly loose within the cage, minor adjustments in the alignment of the parts to be assembled are possible. Clip cage nuts can slide easily along a panel edge whether is level or inclined. They can also be mounted within rectangular mounting holes in the middle of a panel. In smaller dimensions alignment and retention are ensured using a lip which fits into the mounting hole, allowing the nut to slide into the correct position and keeping it in place.
