Wow, I just read my posts and saw I did the same thing today at the hardware store that I wrote on line*. No wonder I've been having trouble!
Time has passed and between some painting deadlines on my smaller easle and a visit to the folks, I hadn't had time (or kept forgetting) to stop at the hardware store again. The short 7/16 12 pt was working, but I had to use two hands. A deep 7/16 12 pt did not fit (go figure).
Today I found it! It was a 3/8 drive, 12mm 12 pt deep socket. Now I can crank one handed--much quicker!
Thanks for all the help and education. My main problem was that I didn't know there were different points (very teeny tiny symbol on the socket labels). Your problem in helping was figuring out what the heck I measured!!!
*I looked at my previous posts and my brain seemed to spoonerate 3/8 inch drive with 7/16 diameter size. I was thinking 7/16 whilst writing or saying 7/8. Hardware guy (they keep the sockets locked up) probably thought I was nuts! Whereas you all know I'm nuts...
