So I used blue loctite on my Benchmade Griptilian 551S. I was just wondering if it was still OK to adjust the pivot a tiny bit looser or will it break the bond and ruin the loctiting? I just loctited it so that the screw wouldn't back out and create bladeplay during daily use. I just adjusted the pivot and it seemed fairly easy to adjust, but if i have to i'll re loctite.
 
I think blue loctite sets in 30min and cures in 24hrs. I would adjust it and leave it, then check it in a day or two.
 
Unless you remove the pivot screw, Blue Loctite does a good job whether it is disturbed or not.
 
Blue Loctite seems to still work in this application even after some minor readjustment after the loctite has set.

If you find the pivot getting loose, then reapply.
 
Ive actually never really had a problem with pivots getting loose, i do it because when im out and about i don't normally carry torx bits.
 
If you're worried about the blue, get the purple (#222). It is much more re-positionable than the blue.
Excellent for the smaller screws.

Gunsmithing trick, you can heat the blue loctite a bit by touching the screw with a soldering iron tip, then reset your screw. The blue loctite should harden and reset without you needing to remove and replace.
 
why is it when i get a knife theres loctite blue on it but its light and looks like the chalkyness of powder for powdercoating? when i do it i apply it then assemble and if i have to disassemble it looks like hardened glue?
 
The industrial product is different.

If you look around, you can find all kinds of different blue "loctite". I like 232, 243 and 248, personally.

Many different kinds of blue "loctite" 240,241,242,243 etc...
Each has it's own chemical properties, but they all do the same thing.
Product from different manufacturers will also "look" different.
Loctite, Permatex, ND Industries, Pacer.....they all make blue threadlocker and they all look slightly different.

The heating with a soldering iron trick works too, as mentioned above.
I just find that the blue is overkill for such small screws.

I've noticed that the fit of the screws makes a big difference.

Some companies use a rather loose thread engagement, while other companies use a tight thread engagement. Then there is thread counts, high to low, and the material of the fasteners.

Benchmade seems to use a rather loose thread fit sometimes - it is one of my irks.

Loctite 242 is probably the most common medium strength thread fastener. It works.

243 and 248 seem to work better when there is some oil contamination issues. I like 248 alot as it is in a paste forum - comes in a 'chapstick' toob.
 
I used to use Loctite 242 on my pivots but switched to teflon pipe tape. It's easy to apply and you don't have to wait for it to cure. I didn't move my pivots once the Loctite cured because it wouldn't hold as well then.
