Vintage Snap On Socket Driver Part # Differences?

[bjc4073]

I am looking to find some socket drivers on Ebay, and see there are a number of different models. I am looking for one in 1/4", 3/8", and maybe 1/2" with a female on the top of the handle to take a ratchet. For example, 1/4'' has TM4CS, TM4CSA, TM4B. Which one is best, and what are the equivalents for larger sizes?

TM4CS is a TM4A with female square drive in the end of the handle. Using the search function on the linked site will find most Snap-on part #s 1980s or older.

A, B, etc suffixes are revisions. So TM4CSA & TM4B are newer versions of TM4CS & TM4A. In this case it's a change from the old to new style hard handles.

Excellent information. How about the larger sizes? The F40 is the only one I can find, but it it has no drive for a ratchet.

From the same #700, 2003, catalog as I posted earlier. 3/8" isn't near as common as 1/4" drive IME. And since you also mentioned 1/2" in your first post I can't recall ever seeing one of those from Snap-on or any other manufacturer.
