Tap drill chart and three wire thread measuring chart

[Tenn]

I made up a chart I use for drilling holes to tap threads and also a chart for three wire measuring of bolts of specified threads.
Thought I'd share it if I haven't already ?
The charts are identical just different formats; jpg & pdf

Thanks, Chris. This picks up where my other charts leave off.

I can never find my charts when I need them so I download some free apps for my smart phone. It is always on my belt
