Which 8-point sockets? ‘Complete” socket set

[macgee]

I most definitely keep a 8 point set in my car. Learned the hard way when hitting up tool sales and have to unbolt 50 year old machines and vises off work benches, 12 points don't work on a lot of the common square nut sizes that I've come across.

In the workshop this week, I've had to use them several times when rebuilding an old Craftsman lathe, they use a bunch of squares, especially the milling attachment. 8 point with a hand spinner set up in the shop.

a square nut where each corner graduated outward and terminated in these little tiny feet or pads. Like a pyramid with the top half cut off and the remaining edges were a concave curve down to the bottom corners. The square size would be different at each measurement along its height.

possibly a weld nut?

That's what it sounds like to me. Weld nut which had all the weld tabs broken off the mounting material. Very annoying to work with.

It could very well have been, although I did not see the evidence of that on the surrounding sheet metal (which could have been the problem!). In any event, it still needed a socket to grab it, and the standard 8-pt sockets would not have done it.

Being the Craftsman nut I am and wanting to have all the standard sockets, I would go through the catalog to make sure I had all the sockets. Have been collecting the catalogs from about '89 to '14ish. There are a total of 11 sockets, 5 in 3/8" and 6 in 1/2". The 3/8" are 1/4", 5/16", 3/8", 7/16" and 1/2". The 1/2" are 7/16", 1/2", 9/16", 5/8", 11/16" and 3/4".
