I still think they should sell 10mm sockets in convenience packs, with a mix of deep and shallow, 6 and 12 point sockets. It'd save a lot of wasted time...
I read this and thought the idea was brilliant! 10mm and 1/2 inch are ubiquitous! I confess that I have purchased quantity sets of 10,1/2, and 3/4 open end & ratchet combo wrenches for that very reason. I just bought multiples of the singles so I could have them handy where they are needed all the time.
Then I saw
@Dan Dubeau 's post and went WTF! It's been available already! I just didn't know it!
Mind you, I like the combos because you don't need the ratchet handle.
I might have 2 dozen singles like this. Mostly farm equipment and machine shop applications. I have tote boxes for each machine that stack together. I keep all the pins, adjustment tools, and wrenches needed for that machine in one place.
For example, when I head out to plow, I grab the tote for the plow, hook up the plow with the plow pins in the tote, put the tote in the tractor cab, and go plowing. If I hit a monster rock and break a shear pin, I grab the tote, set it on the plow beam, drive out the broken pin with the driver tool I made that is already in the tote, and change the shear pin with the two 10mm combo rachets from the tote and a new pin from the zip lock bag of them that is already in the tote too.
I prolly have a dozen such totes. Best thing I ever did. Walking back to the shop every time I broke something was just stupid.
