Generic Bolt ID and Torque Chart
Posted to the Waveform Library on 7/8/2017

Click To Download

This chart allows you to identify Metric and imperial Bolts, convert sizes from imp to metric find generic torques in Nm for reusable bolts , convert Nm to ft/lbs Id threads and work out tapping drill sizes. Due to print errors in many printers You must check the printout on the 1mm pitch thread for accuracy - each thread must line up with a 1mm ruler - expand or shrink until your printer produces an accurate 1mm across the page print on the 1mm thread.
