What’s a good compound to put on threads of a pivot screw thats sticky enough to stop it backing out but won’t set hard like loctite. I was thinking about pipe dope.
 
Clear nail polish will do it, and it dissolves in acetone if you need to clean the threads. Acetone doesn't play nice with plastics and some synthetics though, so remove the screw first. Also ask the owner of the clear nail polish first, if it isn't actually yours.
 
They make different grades of loctite. Get the purple loctite, it's the lowest strength grade, made specifically to not hinder easy disassembly with hand tools but still prevents inadvertent loosening

Don’t need loctite that sets hard and then breaks loose as soon as you turn it. Want to be able to do minimal adjustments without removing screw and re-applying each time. I’m learning that Benchmades need adjusting all the time, even after being broken in.

That's strange. Where did you learn that? My Benchmade knives don't require adjusting "all the time". I carry a Taggedout everyday and it has never needed adjustment. The only reason I can think of why a Benchmade would need frequent adjustment is that the person assembling it did not use Loctite.
 
Loctite #222

It’s low strength and made for tiny screws. The trick, is to let the knife sit for 48 hours without moving the action after application. . If you don’t wait, the bond will fail and you will be trying again.

The upside of this process is that you will easily be able to remove the screw later.
 
I personally use cheap blue loctite from that cheap tools store and it works great on pivot screws. I've never had a problem loosening or adjusting
 
My only Benchmade that needed readjustment had some exfoliative corrosion on the underside of the pivot screw head which, due to the swelling, tightened the pivot. The screw was not “stainless”.

The proper type of Loctite? There are a BUNCH.
You need to use the correct product for the results you're trying to achieve.
And if you don't read the instructions, you don't know what you have or how to use it.

Vibra-Tite VC3 Threadmate

I've used it myself and it works great on pivot screws.

It is intended specifically to resist shock and vibration, so it doesn't dry hard. It becomes gummy or rubbery instead. It starts to set pretty quickly too. It's bright pink colored as well, so you can immediately tell it apart from Loctite. It also doesn't react with plastics, unlike loctite which I found out can dissolve the plastic scales on my swiss army knives! :eek:

You can buy it in a little tube just like loctite, or you can get it in a bottle.

Reading directions is good, yes.

Thanks! Finally a simple answer to a question that, to anyone with an IQ that reaches double digits, should have been pretty simple.

I didn’t ask "the proper type of loctite". Your post doesn’t pertain to anything I asked. Better find a new drug dealer
 
Have had good luck with the Blue 242 Loctite. Strong hold but doesn't need heat to overcome like the Red.

Also, may want to ease off the attitude...
