Glshooter Posted September 10, 2008 Share Posted September 10, 2008 I have always used Blue Loctite for the front sight screws on all my aftermarket Glock front sights. Well now I have one front sight that keeps shooting loose. The Blue Loctite doesn't seem to hold it. I checked the screw and it doesn't seem stripped. I can try Red Loctie I guess but that is supposed to be permanent and require heat to remove. I don't really want that. What else can I try?

Trust me and try the red loctite...if your front sight is like mine (a Dawson FO on my G34), it will still loosen up after a couple or three thousand rounds. Make sure to degrease the inner and outer threads completely for best results. Red loctite ain't as scary as it is made out to be...it flows better into the tiny threads than the blue. Good luck.

Aircooled6racer Posted September 11, 2008 Share Posted September 11, 2008 Hello: Clean the sight and screw with Brake Clean and use compressed air to clean/dry. Then use the Blue again. That should keep it on. Also check to see if the sight is sitting down on the slide and you could add some blue under the sight as well. I don't like using red unless I never want to remove things since you need heat to remove the screw. Hope this helps. Thanks, Eric Link to comment Share on other sites More sharing options...
lugnut Posted September 11, 2008 Share Posted September 11, 2008 Listen to Curtis. It's really that simple. Removing small screws with red is easy with a little heat. It's not that you'd need a torch or anything. Soldering iron or small plumer torch is all it takes. One other thing to consider- if it does come loose at a match or practice session you are done for the day. hand tightening won't hold it for long. Ask me how I know.

HI5-O Posted September 11, 2008 Share Posted September 11, 2008 Also, make sure the loctite is only on the thread portion of the screw. If you put it on the tip, it could prevent the screw from tightening all the way as the loctite will be trying to compress between the tip and the bottom of the hole in the sight.

BayouSlide Posted September 11, 2008 Share Posted September 11, 2008 (edited) For the record, I've never had to use heat to remove sight screws with red: I wish they were that permanent. Very good advice given, though, about limiting the thread locker, whatever type you use, to the threads itself. I've only used red on a few things in my wrenching career, mostly sight screws but the bolts in the adjustment slots from a set of Yoshimura cams in a a GSXR race bike also comes to mind. Back in my roadracing and motorcycle wrenching days, I bought one small tube of red...but went through a number of 32 ounces containers of blue loctite for everything else Curtis EDITED: because I HATE typos!

HoMiE Posted September 11, 2008 Share Posted September 11, 2008 I've used the Purple loctite (supposedly for fine threads), hasn't come loose in 40K+ rounds. Link to comment Share on other sites More sharing options...

Hadn't run into that, but that sounds like the hot ticket for the problem...the red works better on fine threads than blue, but it seems less than permanent on tiny threads. Have to find me a tube Curtis Link to comment Share on other sites More sharing options...
jmorris Posted September 11, 2008 Share Posted September 11, 2008 I use a product called E6000, it’s an adhesive sealant, just a drop under the head and it stays put until you want it off (I change my Dawson FO to night sights for low light matches.)

gotm4 Posted September 11, 2008 Share Posted September 11, 2008 Try red Loc-Tite or Rocksett, be sure to degrease it well and get it plenty tight. Link to comment Share on other sites More sharing options...
Jaxshooter Posted September 11, 2008 Share Posted September 11, 2008 You can breakdown Red Loctite with Kroil. Let is soak for a couple of days and it will come right off if you ever need to get it out. Link to comment Share on other sites More sharing options...
