I bought what I thought was a 1/4 square drive SnapOn T-Handle today. Only to find that it measure more like 9/32. Won’t fit anything else I have. What can I do to avoid this in the future? Or should I just be looking for 9/32 accessories from now on? Are 9/32 drive commonly found in vintage...
Hmmm, I think I have an older Snap-on drive handle like that or similar. I need to get it out and take a better look at it. Unfortunately, it's in a bucket in the attic with some other tools that used to go to the swap meet.
Here is an M4 in my 9/32” drive set. The handle on the original spinner self destructed and caused the rust in the box.

Here is my 9/32” set as found with the disintegrated handle.
