I'm cleaning my revolver and I remove the yoke screw to clean the cylinder and yoke. I look at the yoke screw, it looks funny, dagnabit, the threaded tip broke off inside the frame. I put the screw back in, apply a little pressure, low and behold the tip comes along, I used a pick to extract it since it was stubborn and wouldn't fall out of its own accord.

Stupid yoke screw

The revolver, which is wonderful in spite of the ginormousness.

I learned a few things too. The 29-2 and this 629-6 don't share sideplate screws any more. S&W made am engineering change in 1988, the new yoke screw is spring loaded, maybe they weakened the threads somewhat when they engineered drilling a hole inside a tiny screw to fit a spring and plunger. Lesson here is don't over-tighten the yoke screw, that's why S&W put a little drop of thread-locker on it, the old style can be made snug w/o thread-locker.

Midway carries the new parts for stainless N Frames, (yoke (880034) and sideplate (815190)., they have the new style blue sideplate and yoke screws too. Midway carries the old style blue parts too, except the old style yoke, flat head (193796) and sideplate (152620). I went googling and found that Jack First has the old style yoke screw as well as the old style sideplate screws - https://jack-first-gun-parts.myshopify.com/collections/smith-wesson-old-model-n-frame

E bay is a good place for parts. People sell all the parts off of destroyed firearms. Handy to have a selection of spare screws and springs.

If a design doesn't need to be fixed, you can be sure an engineer will try to fix it anyway. Good info to know. My 29 is from the 80s so it has the regular screws.

Jack First and Numrich Gun Parts are excellent resources for tons of stuff for those that don't know about them.

Thank you henpecked.

Got my parts the other day, installed the new yoke screw, snug, not too tight.
