Need to add a precision adjustment to a shopmade jig? Want to position it, level it, or move it in small, accurate, on-the-nose increments? Use machine screws! Certain sizes of machine screws have a thread pitch (the distance between each thread) that corresponds to a small common measurement. This is true for both Imperial and metric screws, and you can take advantage of this when building jigs and fixtures. Want to see more?
