Permatex 29040 Penetrating Grade Threadlocker Green, 36 ml

I used this threadlocker to hold a pivot screw tight on a pocket knife. I wanted something that would come apart without heat and only hand tools if I needed to service the knife. After shaking the bottle, applying to the screw, letting it cure for 24 hours then trying out the knife it seemed OK. After opening the knife a few dozen times over a few days the pivot screw worked itself loose. It might be good for some applications, possibly the screws for the knife scales, but it wasnt satisfactory for mine. There was no force imparted to the screw other than the vibration from opening and closing. I have since used the blue threadlocker and it has not come loose or backed out. I only gave it three stars as Im sure it has its uses but in my case it was not satisfactory.

Seems to be doing its job.

As mentioned provides for screw retention: also for easy removal.

Great!!

I used this thread locker on my Kershaw Onion Leek because after I field stripped it I realized after using the assisted opening feature the main screw on the pivot would come loose. This made blade wobble and made me a little uneasy so I ordered this. I ran some on the screw for the pivot, screwed it back in, let it sit, and sure enough my knife blade hasnt wobbled for over a month. I just now had to replace the thread lock on it after one month of hard use. Also weirdly, I did accidentally taste this and it tastes very sweet so Id keep this away from the hands and mouths of small children or it may be consumed!

Works as advertised. Stronger than expected. I tightened the thread down with a screwdriver and now cannot loosen it without a screwdriver.

I use it for my archery threads and works perfectly!

Messy but works great on rifle scope bases and rings. Things stay put after curing and can be easily loosened with a judicious amount of torque and hand tools. Cheaper than loc tite and works just as good.

Worked as expected.

The product never hardened.
