A coworker of mine recently introduced me to one of the most awesome tools ever invented by man – the cage nut tool.
This tool will save you countless hours normally spent slaving away with a flat-head screwdriver AND will save your knuckles from the relentless beatings they’d otherwise suffer at the hands of a cage nut. I found one in the bag of accessories that comes with an APC four post rack. Do yourself a favor and get your hands on one.
In fact, I’ll go ahead and provide you a link to an even more refined version, if you can get past the fact that it looks like a giant pair of fingernail clippers.
