Yoke Screw - Who Knew?

[Hayata]

So I have this wonderful Smith & Wesson 686. Great pistol.

But I noticed I was having some difficulty closing the cylinder into the frame. The yoke seemed loose.

Pulled the yoke screw and thought it looked funny. After some research found out there is a spring-loaded plunger INSIDE the screw.

Who knew?

Ordered a new one and all is well. But you have to order the yoke screw "assembly". I ordered a yoke screw from Midway and it DID NOT have the spring or plunger.

See below

Is there a method to get the plunger to pop back out? It's in there pretty tight.

Leave it in a jar of Eds Red for a week or so.

I hit it with some Deep Creep.

Still nothing...may have to soak it - great idea!

PB'laster should do it, if not...don't know..

That appears to be the "old style" screw in the upper pic... buy the whole assembly, this isn't good approach.

If the plunger spring is broken it may not pop out. If the plunger is magnetic you may be able to snag it with a strong magnet.

Acetone

Top is identical to the bottom screw - just with the uncooperative plunger part.

I had it soaking in deep creep over night.

If that doesn't work will have to try the acetone trick.

Replacement screws are available. I keep a set of blue and stainless for S&W revolvers.

Even the pre plunger screws.
