Door striker screw thread?
Hi,
Are the screws that hold the striker to the door post and the ones that hold the mid post dovetails 1/4 course thread? Mine are not in the best condition and want to make sure on the thread before I chase it with a tap. Thanks |

Good quality tap & die sets generally have a thread gauge that can be compared for thread per inch. I believe a person can purchase them separately.

Just a minute! Henry used a seldom used thread size in the model A. It is the 12-24. A little bit smaller and the pitch is a little bit finer than a 1/4-20. But they appear very similar when seen casually. They are not interchangeable. 12-24 used to be fairly common but now they're almost obsolete.

You don’t want to use a reg tap anyway. You want a cleaning tap, or make one by cutting 4 slots lenghtwise. I bought a set of clean out taps and dies on amazon, and they are great.
