Default S&W 617 extractor rod question

I have a new S&W 617 and I absolutely love the gun. I have one issue. After firing about 500 rounds yesterday, the ejector rod became slightly unscrewed, which caught me off guard as I could not close the cylinder. A bit of investigation showed that the rod had become slightly unscrewed. Naturally I hand-screwed it tight, and the gun functions great again.

My question is simple. Should I unscrew it and apply a bit of blue loc-tite, should I torque it to some specification, or what? I am pretty handy with semi-autos but I do not like to disassemble revolvers.

Advice from the knowledgeable is appreciated. Other than this, the gun is wonderful.

That's the right idea but use purple Loctite 222, sparingly, NOT the blue stuff. The blue is really stronger than you want for this size fastener.

Put empties in the chambers and grab the rod in a drill chuck and tighten by hand. You should be good to go.

Now we'll listen to the usual "they NEVER come loose when they're PROPERLY TIGHTENED and CHECKED REGULARLY".

Your gun ,your choice, but I'd rather use a bit of 222 Loctite and know it's staying tight.

Thanks, Tomcat. I am of the "less is better" school so I'll note what you say. If it comes loose again I will maybe try some loc-tite of the purple variety (never heard of it; I'll check Amazon.) Hoping the damn thing just stays tight.

Sure love the gun. The 617 has rapidly become a favorite. After around 1500 rounds the trigger has smoothed out amazingly.

80 -100 in. lbs of torque.(6-8ft lbs) No loctite.

If you choose to use loctite, use very sparingly so it doesn't foul other parts you don't want loctited.

You can get 222 Loctite from Midway or Brownells or Amazon. Amazon has had the best pricing on "big" bottles and I get those to refill my smaller bottles (222, 242, 290) as I use it on my bikes and cars also where appropriate.

On some of my revolvers the rod would stay tight, on some it would come loose. I just Loctite them so they're not coming loose. With 222 there's no reason not to. It's not strong enough to create a problem with disassembly when you need to. Same applies to sideplate screws and the strain screw. 222 is the appropriate Loctite. 290 works well on strain screws once you find a setting but that's another can of worms. I shoot competitively and during a match is not when I want to be doing maintenance...

80 -100 in. lbs of torque.(6-8ft lbs)???????????????????????

Where did this figure come from except off the top of your head? First, there really is no way to measure torque on this part so this is totally useless information, in addition to being erroneous!

What everyone who owns a S&W revolver needs is an extractor rod tool! Brownells sells one. There are different sizes for J-frame and K-L-N frames. EXTRACTOR ROD TOOL FOR S&W | Brownells

You use this with only your hands, cylinder in one and tool clamped on the extractor rod in the other. You cannot over-tighten with this tool, but the extractor rod does have to be tight. Or, clamp the extractor rod in your vise with a piece of heavy leather folded around it. The rod will slip in the leather before you can do any damage.

DO NOT USE LOC-TITE! This is not a proper application.

Alk, this is just the information I wanted. I ordered the tool. That looks great. Thanks to all; this forum has been a big help!

I would think100ft/lb would strip an ejector. A 3/8 grade 8 NC is only rated at 47 ft/lb
