Can you gents give me some ideas about a broken yoke screw on a 686?
Hi folks,
Well the darn yoke screw sheared off when I was re-assembling my 686+ pro series. Let me state here right off the bat that I did not "gorilla" this, in fact, I used a torque screwdriver and was not even up to 10 inch pounds.
I've got the piece in the freezer and have soaked the remaining sheared off screw "shroud" (as in the screw threads shroud around the spring loaded pin that sits in the groove in the yoke arm) in wd-40. I intend to try to use a tiny screwdriver to see if it will gain enough purchase to unscrew the screw shroud left in the threaded frame hole.
The last thing I want to do is bugger up the threads in the frame obviously.
I know the mothership is an option (i hope they send me a new yoke screw for nothing!) but I want to avoid the shipping and waiting.
I will say that S&W using RED loctite on these yoke screws is a mistake. Why not blue? Why cause more stress on what is clearly a weak part?
Thanks a ton in advance for anyone that has gone through this and will share their story.

Oh no.
Hello friend, and all i can say is they all come red. (Locktite) even on the big guns. I've never had an issue, but just wanted to say, it isnt the locktite. Maybe that was just the lucky screw to break! I would try and use a competent gunsmith or the factory than try and bugger up that hole! The screw itself holds the yoke in place! The threads should not be grinded or stripped in any way.
If the gun has warranty, send it back, tell them the screw broke during a routine cleaning and be done with it! They'll fix it for free!
If you tamper with that hole and "fudge" it up, may cost you the warranty!

100% what Lou said. Don't mess with it and call the factory. It is under warranty until you modify it.

I wouldn't chance it either. There's too much at stake, and there's too big a chance that Mr. Murphy will show up.

I have never seen a yoke screw ever locktited with any grade of locktite. That includes alloy frames as recent as last year production.

That screw should not be tighted too much - the walls are very thin. Once I broke one. I just stuck a pointed thin wooden dowel (a bit bigger than a tooth pick) in the screw hole and turned out what was left of the screw. The wood grabbed with no problem.

I believe the red stain many are seeing on screw threads is not Loctite (threadlocker) at all, but an "anti-vibration" coating that helps prevent the screws from backing out due to the harmonics created by the moving action parts and shooting events.

Thanks for the thoughts folks. Well, whether it is actually red loctite, or a red colored "anti-vibration" coating (errrr...kind of functionally like loctite!), but to the folks that say they've never heard of it..well, most late model smiths have it. I've seen many. There's pics on the internets too!

Anyway, thanks again. I like the wood dowel idea, and may give it a try with the frame as cold as I can get it. If that don't work, it's off to the factory. What a pain in the ***.

Using a wooden dowel, may require a VERY LIGHT TOUCH with a rubber of wooden mallet, to break the screw loose.
Remember, in this case, LESS is MORE. Best of luck.

When I did it, the broken screw just turned right out. Maybe I was just lucky.

x2. That's what I thought. I have fought red loctite before, and that's a very different battle compared to the crane retention screw.

The yoke screw broke on my new M69 a few weeks ago, which was a first. I was able to get the pieces out with a small metal probe by carefully turning them. Fortunately mine wasn't as hard as I thought it looked like it was going to be. It broke into three pieces.
Best of luck with yours.
