Jody Waring Posted May 10, 2009 Share Posted May 10, 2009 My Tanfoglio (P9) has a comp that my old gunsmith made, it isn't the semi profile type that the guiderod goes into on the bottom, basically the same style found on a 1911 gun. I was at the range and fired a few rounds and noticed when I was putting it away that AGAIN the comp is turning. While I was shooting I noticed the gun torquing one way which was unusual, but didn't pick up on it initially. The threads are cut good, they aren't a loose fit. Whenever I put a comp on, I wire brush the threads, clean the barrel and the comp with solvent, and use red "Loctite" brand thread locker. It still comes loose, is there a better quality Loctite I should try? I will search their website and see what they have. Anyone ever have a problem with this?

jdg Posted May 10, 2009 Share Posted May 10, 2009 my understanding is that blackmax is the next theadlocker to try http://www.midwayusa.com/viewProduct/?productNumber=330260 Link to comment Share on other sites More sharing options...
Dan Sierpina Posted May 10, 2009 Share Posted May 10, 2009 Get some Loctite 620 from McMaster Carr. It's a high temperature retaining compound. Make sure the parts are Clean! Too much Break Free can degrade the adhesive too. Blackmax is an instant superglue, not a retaining compound. Link to comment Share on other sites More sharing options...
R.Elliott Posted May 10, 2009 Share Posted May 10, 2009 Red Locktite will never hold Jody. As you know I'm shooting the same gun/s and I've had this happen also. The retaining compound works very well (I have 648). Link to comment Share on other sites More sharing options...
Jody Waring Posted May 10, 2009 Author Share Posted May 10, 2009 I'll check my local supply store and see what they have, and thanks for the replies. I had considered solvents being the culprit before, but now I only use Simple Green degreaser, and I doubt there is anything too harsh in that to eat the Loctite. When you use this compund, does it help to keep the parts cold when you apply it? I normally do this with Loctite to prevent it setting up too quickly when threading the parts together.

Not too cold or you might get condensation. This stuff does set up pretty quickly though. Link to comment Share on other sites More sharing options...

kurtm Posted May 10, 2009 Share Posted May 10, 2009 Get "Rocksett" and be done with it. You can get it at industrial supply stores! KurtM Link to comment Share on other sites More sharing options...
TONY BARONE Posted May 10, 2009 Share Posted May 10, 2009 Like Dan mentioned 620 Locktite is the product to use and cleanliness is the key. I would use Acetone to prepare the assembly. Link to comment Share on other sites More sharing options...
