I have a Benchmade 530 that's pivot screw keeps coming loose, not falling out, but enough to give it blade play after every other day or so. I have heard somehthing about using loctite to hold it in place, but I have a question.

Isn't Loctite a superglue? I would think it would end up glueing the screw in place, but possibly glueing the whole pivot, or voiding the warranty I would want to avoid. So what exactly is it being referred to, like a specific part number or something? Thanks for the help, I love this knife, but this issue is starting to annoy me pretty badly.
 
Loctite makes several different threadlockers, which are a different animal than the superglues. I've used Loctite threadlockers for the exact problem, and also for many other things, and it works great. Check it out: http://www.loctiteproducts.com/products/subcategory.asp?CatID=10&SubID=48

If you need to remove the screw after you've glued it, just apply a little heat and unscrew. The strengths, from weakest to strongest, are blue, red, and green.
 
Cool, gonna have to pic up a bottle tomorrow to fix this thing, so tired of it.

Bob, normally when you apply LocTite you just squeeze a drop out from the tube on to the threads... BUT... for use on your pivot, that might put too much on, allowing it to get outside the thread area into the pivot itself. Instead, squeeze some out onto a sheet of paper, did the end of a toothpick into it, and use that to apply to the threads. You don NOT need to fill in all the thread area. If you fill in two lines of thread that will hold well enough as it spreads out from being screwed in.

I recommend ONLY Henkel Loctite thread lockers, because I know when you buy blue Loctite, you get removable thread locker. Stay away from red, it requires around 400F to remove. There is a penetrating green, which is very week, then there is a green which is a CA glue that you might encounter which is basically welding parts together.
 
I just got some of this stuff a couple weeks ago. My Delica's pivot hasn't budged a bit, and there has consistently been no more horizontal wiggle.

This is not true, if you apply it correctly its no harder to remove than blue loctite. I switched to using red a few years ago after having hit and miss success with blue, I can still take the screws out with no problem and knives I have not touched (no adjustment) in years still have no play.
 
You can also use fingernail polish, I usually go for the clear. We used this instead of loc tite for years when I worked in a bike shop. It is quite a bit cheaper, works good, and you can still remove the bolt without much trouble in my experience.

You can also use plumbers teflon tape which you just wrap a little around the threads. It also works pretty good and you don't have to wait for it to dry or worry about it getting into other places.
 
I used Loctite for a good while but have switched to Teflon (plumber's) tape. No mess, no waiting for it to dry, and it's cheaper. :thumbup:
 
I have used the red for 15 or more years in the pharmaceutical field. Never a problem to remove and held well. Use a service removeable product. Don't need much as Stichawl said. I used one for small sizes up to 1/4" thread and another for larger screws. Make sure the threads are clean from any lube before you apply the Loctite.
 
i use blue loctite on my guns on the grip screws, on the mag catch extension, and on the screws of my thumbrest. My first folder was an S&W extreme ops and I lost one of the clip screws within a few days so the first thing I do now when I get a new folders is to loosen each screw just enough to see some threads and apply blue loctite with a needle then tighten. i do this one screw at a time loosen, apply loctite, then tighten before I go on to the next screw.
 
I've only had one or two problems that I can recall removing a screw that had the red Loctite on it. Blue or red, you can usually remove them with a modicum of force. If you're using Teflon tape ensure you're wrapping it in the right direction. Wrap the tape from left to right as you look down the male end of the pipe (not the end that contains the Torx or Phillips head). I've never had a problem using Teflon since I switched to it.
 
Rather than Loctite, I use teflon thread tape. Allows for easy disassembly, adjustment and readjustment, and there's no clean-up like you have with Loctite when you want to replace it. Takes only a tiny strip, cut with scissors ... a small, inexpensive roll purchased from Lowes, Home Despot or wherever will last pretty much forever if all you're doing is knife pivots.
