Pocket clip trouble

So I love the gripptilian, i've had 4. And with every one I've had the pocket clip gets loose to a point I traded it or just take it off. Does any one else have that problem? And yes I have properly applied locktite and it doesn't help.
 
Do the math. The liner is about .040" thick. The screw pitch is 56TPI. There are only 2 female threads holding the clip screw on. 56X.04=2.24 TPL (Threads Per Liner). This why I prefer frame locks over liner locks.
 
I'm not trying to split hairs here, but I personally know the liner on the mini is .045" and on the full size .055".
Just for the record. ;)

I have had no issues with the clip screws loosening up and I dont use loctite.
It could be the way your clipping it or some other unknown effect causing them to loosen up.
Do you leave the knife somewhere it just sits and vibrates, like in your vehicles console or glove box?
That has loosened other screws on me before.
 
I've been carrying BM's daily for roughly 18 years. I have never used loctite and have yet to have any screws loosen up. That includes the pivot
 
I've never had either a pocket screw come loose or needed the use of Loc-Tite. Wonder what causes this problem?
 
I have never had clip screws loosen either and I don't apply any thread locker.

I carry on my belt.....no issues.
The only time I have had screws come loose by themselves; was when I left my knife in the center console of my truck.

Thanks Keyman. Never actually heard of that being an issue just thought it could be a possibility. Shows what I know.:foot:

So the mystery continues...

The reason I said about .040" is because I don't own a Grip. I measured the lock plate a model 943. But using your number (.055X56TPI=3.08 TPL), that pocket clip screw is now hanging on by 3 threads instead of 2 1/4.
 
If you're trying the Loctite solution, be sure the glue gets down to the metal liner and use the red grade.

Do not use red! Use blue 243. Loctite is based on fastener size as well. Even purple will work. Red is permanent and is a pita if you ever need to get the pocket clip off.

You won't have any trouble with the red if it's only holding 3 threads.

I've got a Spyderco that the previous owner used red and I didn't know it. I completley trashed the heads trying to get the screws out. I had to grind the heads off and use a heat gun and a screw remover to get the damn things out. Had to buy a new clip and screws from Spyderco.

I can't think of any good reason to use red loctite on clip screws.
 
I only used blue. I carried in my pocket and no I didnt leave it in my car. It may be that the way I hold it pulls on the clip but I dont know
 
Did you adjust the screws when you first got the knife before the problem started. You could of damaged the threads and that is what is causing the issue.

You mentioned you have had this issue with 4 Griptilians. Obviously this is not a one off thing and my suspicion is it is something you have done to make this happen. There is no way this would happen to all four knives.

When you say you properly applied the loctite what does that mean to you?
 
I'm not trying to start a flame war but "RED LOCTITE" is a stupid suggestion.

1) It will work but it's designed to be permanent unless heated over 500 degrees, and on much larger bolts. The kind of things you have machinery that you can attack with a torch. If he needs to replace the clip or want to remove it, he'd probably be S.O.L. Unless you can find a way to heat the threads to 500F without melting the handle.
2) It may only be 3 threads but those are small screws, with small heads. I'm not saying it's imposible to remove after using red loctite, but you aren't putting the odds in your favor. The odds of a stripped head are damn good (coin flip). s
3) they actually make non permament LocTite for applications like that. If Red works, why would they do that? Oh, because the torque required to break the threads loose is then proportional to the bolt size? Don't quote me on this but I think the purple is actually more flexible and vibration resistant


Regarding the Original Question

Since it's Blue, it should work. The only things I can think of are;
not cleaning the surfaces,
not waiting the full cure period (a day, not 10 minutes).
or not having enough at the contact points.
it could also be removing and replacing screws over old previously cured loctite, but not likely


Since most people don't even need thread locker, you may be the problem (read:variable). Do you operate a jackhammer? Do you frequently bang in to things?. Something is working the screws loose, that seems almost unique to you
