Anixter Components (formerly Heyco) has introduced a range of steel cage nuts for panel builders. These fasteners snap readily into square holes and do not require special tools for assembly, allowing OEMs and panel builders to save valuable time during installation, plus associated costs. The cage nuts fit two standard square hole sizes – 9.5mm and 12.8mm – and reliably fix screws with thread sizes M4 to M10 in light and heavy duty applications. They combine the versatility of spring steel fasteners with the high strength of a multi-threaded nut, and are suitable for many applications from 19in racks, shelving and networking hardware, to heavier equipment such as uninterruptible power supplies.
