For all who spent much longer than they wanted for this project searching the garage and only finding the the 9 and 11. Close to defeat you find a 3/8 and think, "maybe this time" and it just slips, so you pick up the adjustable wrench in shame. You slowly weep as you spend ages turning the bolt only 10 degrees with each twist.

Everyone has lost a 10mm wrench or socket at some point in time. Sometimes many times. For SAE, it's 9/16". I have lost many of both sizes over the years. Particularly when I was farming. I planted enough of them in those fields that I should have had a bumper crop growing out there. But nope, it's either poor germination or I live in a growing zone that is uninhabitable for growing sockets and wrenches.

I think that finding a lost wrench or socket is a bad omen. It's always been a predictor of an expensive repair is in my future, and I'm going to need that tool.

Forget that, show us your 10mm sockets. We want to steal them

I thought they were like socks in the dryer.
