My old gray head has ceased to absorb all that it should and certainly not as much as it used to so I need to use CHEAT SHEETS every once in a while.
Attached are some useful ( to me ) charts that some others may have a use for.

I like your charts.
I think I will print and laminate for quick reference.
Gary, you might also find it of interest to know that the bolt head size is usually a ratio of 3/2 of the thread size and the same height as the bolt diqa. Example: 3/8(thd dia) x 3/2=9/16 head size. 1/2x 3/2=3/4", 1"=1/1x3/2=1-1/2"
This remains standard for Hex and Allen bolts, with the exception of the 5/16 dia bolt. There the head size is rounded up to 1/2"
Standard SAE/AND standards
Saves running after another wrench if you know size. Some people are very good at remembering the correct size. Not me!! I need all the help I can get.
Nitehawk, Fractions were beyond me even when I was a child. Thats why my wrenches are in a pile in my toolbox so that I can just keep reaching into the pile til I find the right one. You know... old dogs.. new tricks. :)
I envy the guy that can eyeball a nut and reach for the right wrench. Is that why they invented monkey wrenches because of guys like me ?

Thank you Gary!
Thanks Gary. I saved the files on my computer for reference.
An easy way to gauge wrench size is to figure 1-1/2 times the diameter of the bolt for standard bolts and nuts. Add 1/8" to that figure when dealing with heavy duty bolts and nuts.
