Finally bit the bullet and bought a 24U rack; nice little APC unit. Guy selling also threw in a bag of cage nuts and screws. After mentally stepping on a few pieces of Lego bricks I realized that there are three different sizes of cage nut threads. Lucky me; I have a bag of evenly mixed sizes all the same coloration.
I am running all SuperMicro chassis, CyberPower UPS, and will likely stay on the SM bandwagon vs Dell or HP.
What size cage nuts threading should I standardize on: 10-32, 12-24 and M6? Is there a minimum screw length that should be used? I am not a fan of Phillips but that appears to be the dominant head. I have found Allen and Robertson headed screws but I am not sure if these heads would lead to over-tightening.
Lastly, do I need a washer? If so, does it matter if I use flat or lock washer? Is it better to use plastic or metal?
