Size matters
Over the years I have bought three universal sockets from second-hand tool dealers. Only one has a name and the manufacturer stamped on it, the American made “Ultra Socket”, while another is obviously a close copy of the “Gator-Grip” which is advertised on the internet.
I think the real appeal of these mechanical curiosities is that they can grip fasteners for which purpose-made sockets can’t readily be purchased, and the reason for that is that the system of sizing nuts and bolt heads has changed more than once over the past 50 years.
