Hi all
This is a printable double sided Bolt Drill Thread Chart for the workshop. Laminate it.
The torques are based on standard bolt tensions for reusing bolts.

Important for the THREAD PITCH INDICATOR on the side.
If you print the chart measure the 1mm thread form with an accurate rule to make sure the printer is not distorting the thread pitch forms.
Use the peak of the bolt to the peak of the thread forms to identify bolt threads pitch. (It is not a thread gauge so don't try to use like a thread gauge)
