ZT 0454 Pivot screw issue?

I've found that as I repeatedly flip open and close the ZT0454, eventually the pivot screw starts to come loose.

I've tightened it with the appropriate tools, but inevitably after a few hundred flips it's loose again.

Is this normal? I doubt that. Is there any way to fix it? I'm reluctant to overtighten the screw.
 
Use Blue Loctite/Permatex on the pivot screw. Tighten it to the desired tension.

I wondered about that, but the idea of putting loctite into my beautiful (and crazy expensive) collection knife (definitely not an EDC) is a bit anxiety provoking.

That is understandable but it's pretty normal with repeated flipping. If you clean the screw and pivot hole well with acetone and dry it you only need a 1/4 of a drop on the last two threads. Set the pivot and let it dry overnight. A tiny amount will do the trick but not lock it up so bad in the event you need to take the screw out.
 
If it's a collector piece and not an edc, why are you flipping it hundreds of times?

I would think a future buyer would have less of an issue with a pivot that has a little blue loctite (most come from the factory with it) than with a knife that has been flipped hundreds of times...
 
Blue Loctite as has been stated previously by others. I always apply it to the pivot screw of any knife upon reassembly after cleaning and/or lubrication.

- If it makes you feel better, I put it on my ZT0777 pivot without a second thought. Same with all of my other knives.
 
The same thing happened to me and the lock bar insert was not properly installed leading to lock rock as well. I sent that POS back to kershaw they fixed it and now it sits in my pelican case again. When I called customer service as their web page for issues was down when the CS guy asked what model the knife was and I told him a 454 he could not believe it lol!
 
Thanks for the info. Question for those who own both 454 and 777. I find the 777 infinitely smoother than the 454. Is this true for other owners?

As for why I am flipping it hundreds of times... it relates to the question I just asked.... The 454 just wasn't as smooth as I had hoped it would be. It's the most expensive knife in my collection, but far from the smoothest opener and closer.
 
If you don't want to use the blue loctite you can use the loctite tape. I prefer it as it does not get into the pivot or bearings if you go nuts.

My 0454 pivot hadn't come loose, if flipped a few hundred times. I wouldn't overtighten it, just use either loctite.

There's a Loctite tape? I've never seen this before. Hmm... interesting.

Not all collector pieces are for future sale -- some people collect them just to fondle, admire, and in this case, flip.

I had this pivot issue with every ZT I've owned with bearings. It's a little bit of a pain.

Does it trigger more of less anxiety than the issue of having a pivot screw come lose every 3 minutes? You aren't going to pour a gallon of. Loctite into the knife. You simply add one or two drops to the male end on the threads, give it about 1 hour to get tacky and set up before you screw it into the female end. Done and done.
