This isn't a question, but an answer to everyone who has asked what is the thread size for S&W stock and sideplate screws. This started as a project to make replica stock screw sets that match the old style screws & escutcheons that were deep and had the collar that was flush with the stock surface as the diamond stocks were.

Often I have seen this question asked and inevitably there is a response that thread sizes have changed over time. This is incorrect. After checking several of my S&W revolvers in J, K and N-Frame, wood and hard rubber stocks, manufactured from 1905 to the 1990s when wood stocks made in the S&W "Stock Job" ceased to exist, this is the result.

The thread size for both stock screws and sideplate/yoke screws was 5-44 NF for all guns checked. This is only logical if you think about it.

Surprise! Now you know. And, before someone contradicts this and says that the new style "Yoke screw assembly" has a different thread, that is correct. This post only addresses the original style solid yoke/sideplate screws. Stock screws do vary in length depending on stock style and frame size, but only in length.
