Wrench for old Greenlee knockout draw stud.

[shteii01]

I was looking on ebay for 1/2" conduit knockout.

My own limited experience is with Greenlee products. Particularly the Greenlee manual ratcheting wrench set.

Anyway. So there I was scrolling through ebay listings and I noticed that older Greenlee 3/8" draw studs have square tops. I am used to hex 1" tops where I can use 1" socket to tighten the die when I am cutting a hole.

So. What did people use on those square tops? What kind of socket? What kind of wrench?

McMaster sells 4 point socket wrench similar to this:

You could also use an 8 point socket and ratchet.

Thanks Bob.
Would some of the 12 point sockets work with it?

Knowing that is a conduit sized knock-out most were probably turned with a crescent wrench. If you must have a ratchet then a proper 4 or 8 point socket is required. If you want to be neanderthal then you can use a 12 point socket.

no neat sig line

Crescent wrench makes sense.

Open ended or adjustable spanner, else a dedicated spanner would have been possible. 12 is a multiple of 4, so yes, a 12 point will work.

Hm. Found another idea on the internetz. Use female end of the extension for the socket ratchet.

The rounding of the square drive is due to either an adjustable wrench or a 12 point wrench/socket.

A 4/8 point socket doesn't cost much and is the proper tool to use.......

Yes, I think I will get 4 or 8 point if I buy one with square drive. Thanks again Bob. I did not even think about square sockets/wrenches even though they use them for pipe plugs and gas shut off.

Refrigeration wrenchs are ratcheting wrenchs with female square heads.
This is what I use on the old style knock outs.

That looks good. Thank you Mike.

Try and put a 1/2" 12 point socket on a 1/2" square nut. It doesn't fit.

Williams is a good source for 8 point sockets.

Yeah you have to go with a larger size. When i disassembled an old Prentiss vise I used to have, there was a large square headed bolt holding the swivel base to the vise body. I don't remember what size square, but a 1-11/16" 12 pt socket fit perfectly and worked well, as it wasn't very tight. Plus I always enjoy busting out my 3/4 drive tools.

I've used a diamond adjustable wrench on mine since 79.
