Head over to Garage Journal and your head will explode (in a good way) because of all the tool info.
Crash course on Williams:
-Williams really is a subsidiary of Snap-on. It's a brand aimed at industrial customers, mostly.
(
Link to the Snap-on industrial brands website)
-Williams has two tools lines, an imported line and a USA-made line. Most tools are available in both a USA made version and an imported version.
-Want to know if an item is USA made or imported? Look in
the online version of the catalog, by following this link. The USA made items are clearly marked. If it's not marked as made in the USA, it's imported.
-The USA-made tools generally even have a Snap-on date code.
-The USA-made, 36-tooth Williams ratchets use the mechanism Snap-on ratchets used to use before they went to 80 tooth.
-Williams offers a line of round head, 72-tooth ratchets that are made in the USA and a good deal from some sources.
-The imported tools are mostly made in Taiwan. They're also usually identical to the same Blue Point tool, except the Williams version is considerably cheaper. If you compare the set listed by the OP to Blue Point tools, you'll see they're identical.
The best retailer I know for Williams tools is
Tools Delivered. They have good prices and fair shipping, from my experience. They post on Garage Journal. They also list the country of origin for the tools they sell, which is important to me.
