screw on my 610

[jiminthe burg]

Hi
Wanted to ask a question re the screw that holds the cylinder assembly (opposite side  from the the cylinder release)

On 2-3 occasions  over  past 2 yrs , that screw that secures the cylinder assembly to the revolver loosens to the point that the revolver becomes inoperative.  It is on the opposite side from the cylinder release. It is a very quick fix w/ a screw driver.

I was not using really strong loads-8.5 grs B D w/ a cci mag primer under a hard cast 180 gr projectile. I am wondering if the loosening occurred over a period of time and it just caught up with me.  On a few occasions, I have had a piece of brass that may have needed treatment w/ a Lee full sizing die and have had to tap the rod that ejects the clip w/ the rounds but too hard

Has any one else had this problem w/ a 610 or another n frame revolver such as a .357 or .44. Just curious. Fortunately, it is a very quick fix. Thanks for any inform.

You may want to add some locktite but not permanent set...each time you open the cylinder it rubs the screw.

I had the same problem with a 45 ACP Model 625.  Removable loc-tite fixed it.

It's not uncommon.  I've found that once they start loosening, they continue to loosen.  I've used Loc-Tite on some that worked for a while, but still loosened up.  The problem isn't the thread locker, necessarily, but the way the screws wear.  A closer look at things showed corrosion and wear (scoring) on the pin-end of the screw actually allows the yoke to torque on it.  Loc-Tite is temporary.  Anymore, once one loosens up, I Loc-Tite it, while the replacement screw is on the way, then replace it once it loosens again.  Numrich has them in stock.  Part# 313790, and fits any 610 (all revision numbers).  Less than $5.  New yoke screws come with the correct dry thread locker pre-applied (make sure the frame threads are clean/dry).  S&W recommends replacement of this screw any time it's removed, but I've R/R'd them about a dozen times before they need replacement.  While ordering, might as well order yoke screws for all your revolvers (same shipping charge).  If you order from Numrich, call the number on the top of the web page, and a recording will give you a code to use for an online order, and they'll cut the shipping charge, sometimes to zero.

Thanks for the replies-ordered the yoke screw as per suggestions from DM 1906

It's been a couple months since I ordered from them.  Are they still discounting the shipping after the phone call?

@ DM1906- Sorry, didn't see your latest post until today.

I can't remember what occurred but I did not get a discount. I am thinking that I ended up ordering them on line. $15.00 for 2 was the " OTD " price.

I applied some temp. locktite, after my last session,  and today, got thru about 12 full moon clips and noticed that things were a little tight in terms of the cylinder turning and after firing about 3-4 more clips, I had to loosen and re-tighten the screw but trouble again but I finally managed to finish 26 clips.

When I got home, I cleaned the 610 and put a new screw in and rotated  the cylinder w/ ammo and it worked just fine so I think it was time to replace that screw. I am guessing that I have >2000 rounds thru it.


While i prefer autos, the full moon clips make for some fast shooting w/o having to reload clips and brass retrieval is a breeze, lol.  This is a very accurate pistol and I have found loads that it likes. So, it's definitively a keeper
