A lo0t of times the cheap wrench seems to be looser as it gets older in a size or 2 and it usually isn't the tool but that the tool has been damaged. Anyone worth a pimple on a mechanics *** should be able to determine if a socket or box end doesn't fit right and in a career with 1000's of sockets its really only happened a handful of times, a few pieces from Sears and a couple were way off blems.
A few where someone has damaged them with impacts and long bars and 1 set about 20 years ago from HF was deep metric and others I know got the same one, it really hurt them for a while but they changed.
I think I found the last of a handful of 9/16, had a couple different ones and we really brutalize them but they hqad got used on a job with clamps where we did hundreds and ran off rusty bolts with a 1/2 air gun. They were good enough to twist the bolts right off. I have used Olympia, HF, MIT where it was all or nothing, broke handles right in half with cheaters and even beat some with a nail hammer and they still fit and work and even have collected a few with the old 70's style thin boxes that work really well.
The Chinese tool worked its way in to our biz slowly. Some of the ultra cheap sale store stuff of the 70's was bade, even then the **** were invading with a few things, I got WT Grant wrench set that was brutal but the 40 pc 5$ sockets were never reliable although on occasion spot a survivor that works and actually went to the well in a bucket for a 13 shallow and to my surprise it look like **** but worked well enough it got tossed in with the rest.
Eventually we bought a few things for duplication mostly and I figure the fact I beat a half a dozen 1$ wrenchs with impacts over the years rather minor and actually could have warranted them. They got mixed from occasional use to just being wrenches and my mind cant help the difference to some respect that I am not racist and need a reason to choose one over the other if there isn't some mechanical reason to do so. I actually get a sense of relief when I spot one when I need it and know its been proven and tested or it wouldn't still be there. Only bent wrench I own is a Snap someone spread the jaw on, they could have ruined one cost a dollar instead and I have really taken them out of circulation anymore anyway and added to the tubing wrench drawer.
I am willing to sacrifice a bit of loss risk for availability and common combo and some sockets really don't even have a home, they float around between trucks, tool boxes and golf carts. We have about 100-150 combo wrenches on racks with pegs in 3 spots and then a few things basically those in the pic as needed in everything that moves.
