Some chief engineers might well sling those wrenches right out of the hangar door if they see one in your toolbox!
By the way, not all 7/8" deep sockets are deep enough for spark plugs. Some only grip half of the hex so take a plug along to the toolshop to make sure you buy the right one.
Phew........... better not let my Chief Engineer see it then.................... wait on a moment, I AM THE Chief Engineer
They do not really compare to an adjustable as they are designed to work on more than two faces of the nut...
