Bolt Reference Chart for Makers

Makers tend to use a lot of bolts / machine screws in their projects. Often times I have found myself using other peoples reference charts but they never really nicely fit on a single page that you could print out and pin to my wall. As a result I thought I would throw together a chart for both Metric and Imperial sizes along with the tap drill measurements etc. Hopefully you also find this chart useful and find yourself referencing it as much as I do. If you happen to find any errors or want me to add a size that isn’t already there, let me know in the comments below.

Here is a downloadable copy. Printable Bolt Size Reference Chart (PDF)
