If you buy cage nuts then you probably have non-trivial life experience with rack components from different vendors etc even have slight differences in the size of the holes or the stiffness of the little tabs that hold them in place etc Also, you've probably worked in a cabinet where the screws are too short (and you either have to forego washers, or try tightening some threads, etc.), or where the screws break easily, etc. I hope , They also worked with good cage nuts that come with washers will not damage the unit, the nuts are the same, considering how much play they have and how tight they are and where the bolts are of high quality and don't snap right away. These are those nuts in a cage: be sure to buy them.
