ASME B 18.2.2- Heavy Hex Nuts 1 1/2" - 2H - Black |

The Cage Nut is a meticulously engineered fastener, boasting a unique composition of a robust metal cage paired with a versatile, movable nut. This ingenious construction permits axial movement of the nut within the cage while simultaneously prohibiting rotation. It is expertly crafted for instances needing a formidable threaded connection on thin sheet materials, offering unparalleled strength and reliability.
Main structural features
The Cage Nut is crafted with precision, featuring a streamlined, one-piece stamped metal cage that houses a square or hexagonal nut. Equipped with resilient elastic springs on either side, this fastener effortlessly engages upon insertion into a square sheet hole, allowing the springs to expand and secure the sheet's edge. The floating nut design allows for a vertical movement margin of about 3-5mm within the cage, adeptly compensating for any installation discrepancies.
Typical application scenarios
This exceptional nut finds its extensive application across various domains, including the assembly of network and server cabinets, automobile cab installations, and securing electrical housings. It is exquisitely suited for use with thin materials like wood composite boards and particle boards, which are unsuitable for direct tapping. By pre-punching square holes, one can achieve a robust threaded connection, making this nut an indispensable asset in numerous structural applications.
