Query: Good quality, hand-installable

I am particularly happy with this pack of cage nuts. While this certainly seems like something to not get very excited about, the last set i had were probably more "heavy duty" but this meant that i had to use pliers to flex them enough to install. These are flexible enough that i can install them just by squeezing, which is a major plus in my mind. Either way, once a screw is put in it the actual clip no longer matters, so i think these are great. P.S. As to the reviews above about thread size, the nuts I got have "M5" stamped on the side of each one as well.
