Keeping pivot screw from turning???

Hello folks. A while back I posted that my Manix had quite a lot of blade play. My star tool was returned to me (loaned to a buddy) and I tightened the pivot. Problem solved. I actually like the stiffer motion in the blade too.

However, it does not take long before the pivot loosens again. Probably a few days of occasional use. So, I always tighten it up again and we are back in business.

Is there a way to prevent the screw from loosening so easily? Something I can use to add a bit of friction to the screw to prevent it from loosening maybe?

Any thoughts on this would be helpful.

Thanks.
 
Ok guys, I'll do it.:) Go to Lowes and look in the glue section. Look for BLUE Loctite. This will be what you want to use. ~6.00 and will last a LONG time. Just a drop on the pivot screw before you go to sleep and it will keep that pesky screw from comming loose. * remember, BLUE Loctite.
 
Wwells20 is right. Spyderco pivots often need a little locktite (or other similar product) more so than other manufacturers. One thing, don't use too much (one drop on the threads is usually all it needs.) If it doesn't hold, then you may need to clean it before using the locktite. You need to take the screw out, clean it with acetone, rubbing alcohol, or vodka. Let it dry and reapply. I've had to do this with a Starmate, Lum and Shabaria and its lasted for years.
 
Blue Loctite. Got it.

I get the impression this is asked a bit?

Thanks for the tip.
 
BLUE Loctite Thread Locker has been added to the pivot screw. I am confident that it will work fine.

Loctite has a large number of products out. I almost bought the Blue Loctite Super Glue...Lowes had many more Loctite glues than thread lockers.

:eek:
 
Green is really runny and primarily made for penetrating into areas that are hard to reach. Blue is runny enough in my opinion so I usually recommend it. The green will work though if that is all you have but blue is the better choice for knife pivots and screws. Green seems to be a little bit stronger to me than the blue but it is probably because it is so thin it can cover a greater surface area of the part you use it on.

Red is the one to avoid. It is far too strong for small knife screws and requires heat to move the screw after it has been used and set for a while. I have had guys send me knives to work on that had used the red on their screws and then could not get the knife apart again afterward. They sent them to me to get apart and fix locks on or some other such thing. On two occassions the red was so strong the head twisted off the screw it was used on rather than let go and this was even after heating it up with a soldering iron. Avoid the red. Trust me.

I really like using a product called 'Sportsmans Goop' over the loctites. It holds very well and is easier to remove the screws with and it cleans up easier. They sell it under plumbers goop, carpenters goop, household goop and maybe a couple of other marketing names. They are all the same though.

Ble loctite is the general suggestion, however blue is not always successful for everyone,..... and for those whom blue loctite has produced unsatisfactory results........., red loctite has rectified the situation.

The fact is, even red loctite eventually needs replacing, and it is not 100% permanent, thus it does need replacing, and it's results can be undone (just with a bit more effort than blue loctite).
So if blue holds for you, than great!, however if not, than red will solve the problem.

I just wish I purchased red in the first place, and had of not spent the money on the blue, which failed to hold my pivots in place for several seconds.
Fact is, when you loctite the pivots, you want them to hold tight, so why not use the red stuff, which will hold the pivots tighter for longer ???... just my opinion.
 
if you never need to remove the screw then use the red...that and the green need heat to remove and in doing so you might mess the knife up
 
I'd try the Goop before going to the red. Even loctite will tell you the red is too strong for small screws. Use the blue and set the knife aside without using it for 24 hours. When it doesn't work it is most always because the surface was not clean. I've never had the blue give me any trouble.

Well I left the Manix for a while after adding a small amount of loctite (blue). I got back to it today and the entire pivot is stiffer than a pent up donkey in a room full of sheep. Can't even open the knife one handed anymore.

I will need another star tool to rectify this as the loctite has bonded the screw and the receiver together. Ugh. I used SUCH a small amount too. Not even close to a full drop.

Anyhow, I suppose it did do what I wanted it too...
 
Even a drop is alot.
With loctite, all that is needed is a dab on the end of a toothpick, that is it.

i agree...i have used it on my endura and its been tight for over a year now, it looked like infamous was set on using the red loctite
 
I've used the red Locktite on my Para, and even had to uscrew the pivot later and was able to. Red works great, I personally wouldn't bother with the blue.
 
You know, I'm a poor college student and I've found that the best thing to hold a pivot screw down for the cheapest price is nail polish. It works perfect for me and I've NEVER had a problem with using too much.

off topic but here is another use for nail polish(clear or a color to match) is if your car has a chip in it, and you don't want it to rust before you can fix it correctly(lets say it is wintertime, and you don't have a heated garage) put a dab on it and it will last for a few months.
 
Tonydahose;

If I was, as you imply, intent on using the red,........ why would I go and purchase the blue ???

How can you assume something such as my personal intention for using red loctite ???

Does it make sense for an individual to be intent on one product, however to go and purchase another product, and experience poor results ???
To spend time paying for, and applying the blue, only to then return the next day, and pay for the red ??
Is that not a waste of time, and money, and is that not an unnecessary hassle ???

I am simply providing assisstance, and suggesting the fact that blue does not always work for everyone, and so red has been successful in those cases, and it is not that uncommon for red loctite to be used, nor is it uncommon for the blue to be unsatisfactory, however when I first enquired, blue seemed to be the most common, and most widely used, except for a couple of replies suggesting the red (only after having trouble with blue), so naturally I tried what was most accredited with good results, being the blue.... and when that didn't work, I went with what was then suggested, which is the red.......; and so I can only support my own personal experience, and of course when someone asks for assisstance, I will state exactly what I know, and if you analyse my respone closely, you will see that I do indeed suggest the red, yet that is only after stating that blue has not always worked for both myself, and several others of which I personally know of.

Well, as I previously stated, I would have preferred to have purchased the product that would ideally hold, and not spend both the time, and the money with purchasing the blue loctite, only to experience unsatisfactory results, and then having to return and pay for the red loctite.

I did infact dissassemble my knife, in order to throughly clean all surfaces, and parts, and allow to dry, and then add lubrication to the joints, and moving parts.
I applied just a dab on each pviot screw, adjusted to the preffered tension, to minimise play, and left for 48 hours, in order to make sure it was set..... only to then have the screws loosen after 3-5 minutes, and when using the torx, the screw came right out without any friction.
So I repeated the process, however this time adding an excessive amount of loctite to cover the screw's thread entirely, and after 3 days, the screws came out again with hardly any effort.
So finally, I applied the red, and have not had to re-apply at all, and no further play has been experienced within 6-8 months of application.

The fact is, is that the red loctite is definately stronger, and described as permanent. Whilst the blue is somewhat temporary..... yet the fact is is that even the red loctite needs replacing, just later, rather then sooner, and so it must not be 100% permanent by any means. So if one adjusts there pivots to the right setting, to eliminate play, then one of course wants those pivots to stay tight, thus loctite is used,... and so why use one product which wears off in say 3 months, rather than another that holds tights for 6 months ???.......
Thus is the reason I state;
"Fact is, when you loctite the pivots, you want them to hold tight, so why not use the red stuff, which will hold the pivots tighter for longer ???... just my opinion."

So,... it would seem to me, that your assumption on my intentions regarding the red loctite, are unfounded in my opinion,... and judging by the fact that the intentions mentioned within your post are none other than that of my own,... I think it's fair to say that my opinion would be fairly accurate in this situation.
 
dude relax..wasnt trying to hurt your feelings. str was saying that red can be a real pain in the butt if you need to take it off. i used blue and it worked for me. it obviously didnt for you so you went to red. per what the company states you need heat to remove the red. i just put in a little note so that if someone uses red and they need to take it apart that you might ruin your knife in doing so. just a little warning. you were intent on using red cuz blue didnt work. i would have done the same.
