armstrong armaloy sockets

[jimwrench]

 Got these three sockets in auction box. They were not my reason for buying box. They raise a couple of questions. They are 6-646 Armaloy PD (1 7/16 size) and 6-640 Armaloy PD (1 1/4 size) and the other is 1 3/8 size. Question 1: What does the PD stand for? Question 2: Why would previous owner saw off all but about 1/16 of the drive section ? Question 3: what kind of saw did he use ? I'm assuming a woman would be too smart to do this. oh yes the are six point but the picture should make that obvious.

heres the sawed off fellow

While I've not seen that brand name, I have, and have seen other mechanics modify sockets to fit in some odd places.  I would imagine a good brand of hacksaw blade would cut it, or just time spent at the grinder.   I heard of one tool person that was going to collect just modifed tools, owner bent-heated-twisted and such, whatever it took to the job.  Those are interesting sockets.

Ya had to be there.

Question 1: What does the PD stand for?

I believe the PD stands for Power Drive. They are impact sockets

I would guess he used a "wizzer" wheel. Abrasive cut off blade,used on high speed die grinders.
They work on locks ,cut through with no resistence.

Yes, the number series is for impact sockets.

>I believe the PD stands for Power Drive
My guess also, but I could not find an adv or such to prove it..

Keep in mind that the bolt only takes up a small space in the socket, even with the end sawed off, the impact gun would go through the hole, sitting flush with the top of the socket. So, if you were in a *really* tight space, it might be just enough...

Armalloy was just a fancy name for alloy steel, good tool steel will cut it, it just takes a while, but a cutoff wheel would be my guess as well.

also, if you cut the top it doesn't have to be flat, if the socket side had been cut, it would have to have been perfectly flat, as the bolt has 6 sides, the drive end only has 4 sides...

The 1985 catalog calls them Power Drive, but those are older.
