I built these because I needed a set of high quality depth stops. They are very high quality and work perfect. You will need a 3Mx14 bolt and a M3 nut. I used lock nuts list below.  I have 8 total listed below. I also built a container to put them all in. Everything works perfect. 

Check out the other depth stops in the collection.
