Bolt Thread and Drill Gauge Chart

[moorebrm]

First time I have posted here so I though I would contribute a bolt chart I have put together.

This chart provides some information on common metric and Standard threads and bolt torques. A foot pound to Newton Metre converter and a set of thread identification images is included. I have needed to break up the file and compress it for this site. When you print it check the horizontal sizes are correct with a ruler to get accurate thread forms.
ie 8tpi 8 threads must measure 1". If the size is out correct it by scaling your print. I needed to scale to 99% on the test print I did.
Hope you will find it useful.

Those are nice charts. Thanks Morebrm, and welcome to GJ.

When I posted the charts I forgot to mention when you use the quick check thread identification images you use the crest (outer high point of the thread) against the outer high black v image. If the thread is correct then you should end up with a series of consistent diamond shapes all the way along.
If you try to use the image as you would use a set of thread gauges - Crest into the root of the thread - it is not as effective.
