For the life of me I don't see why some entrepreneur doesn't sell bulk 10mm sockets.
Dahszhi Shallow Socket 1/4 Inch Drive 10mm 6 Point -10pcs
I’m having the same sort of trouble, but with box-end wrenches.
There is a comedian on youtube (Charlie Berens) that did a bit on 10mm sockets and sold them with a clip-on thing to clip onto your belt so you would always have a spare.
Or buy 2 and your wife could wear them as ear rings.
Or buy 12 and hang them as ornaments on the tree.
I came across a thrift store that had boxes full of random sockets - just all tossed in there. 25 cents a socket, 5 for $1. I would go in there and replace whatever ones I couldn’t find at the time, and always grabbed whatever 10mm ones they had.
Went in there the other week and he has gone from picking through auctioned storage lockers and garage sales to buying “bulk lots” of unsold merchandise. I was REALLY disappointed. Had to go the auto store to buy a 23mm socket for $7. (Although the thrift store wouldn’t have had it anyway, but...)
I’d buy a dozen. There is always an empty slot on my tool box.
