99% identical to US Snap On Sockets. I know because I have Snap On Deep Sockets to compare. Williams USA outlets don't have the absolutely perfect fit and finish of Snap On's chrome markings or size markings and they come on a flimsy, cheap power strip, but I'm pretty sure these outlets are made in the Snap On factory. Great price for a great set of sockets. I only gave four stars because the rails are so bad. I have seen many Proto/SK bushing guides etc which are great for this purpose but the rail these bushings attach to is absolute rubbish - flimsy and flimsy.
