I'm not sure I am using the correct name of this product. I think it is called Loc-Tite and is used to hold screws and nuts in place. I bought a gel version of a wannabee product in some nameless auto supply store somewhere last fall. I used some of it on those brass spring-loaded clasps that hold sliding closet doors and some bathroom cabinet doors properly latched. Over time the screws were backing out and popping into the cabinets. I figured this was caused by road vibration.
I used this product at least 3 months ago and it has not dried. Now it is very sticky, but not hard like I thought it would be. Has anyone else ever used a product like this and does it eventually dry hard to hold the screws in place?
Assuming you are using Loctite between metal parts and not on the wood screws:
Loctite should start to harden in a matter of hours with full cure in 24. If it has not cured in that time frame it never will. Two things can inhibit cure: one is exposure to oxygen and the other is contaminates such as oil and grease. The typical use is on screw theads where the screw has either a nut on it or is screwed into metal. Within the threads air is excluded and the lack of oxygen enables cure.
I suggest disassembly, clean with alcohol and reassemble with more loctite. One thing I've noticed when using loctite is it seems to cure best when there is some load on the screw - I think the load helps block out the air.
Also, there are different strengths of Loctite that are color coded which all the generic manufactures seem to have adopted as well:
Blue (regular strength) is most commonly used and is consider "removable" (unless using very small fasteners, like #2 screws)
Red (high strength)is considered permanent (but can usually be removed with a little work or heat)
Purple (low strength) I believe is used for very small screws.
Hope this helps
It should dry.
There is loc-tite blue, and red. Blue is temporary, red is nearly forever.

George,
You have several issues. The first and most important, if I read your post correctly, is that you are trying to use this on wood. There is a good chance that the varnish or oil finish is causing the no-name to not work. The second is that this is a no-name product and who knows if it works as well as Loctite.
If you are trying to keep screws tight in wood then you might try Gorilla Glue. Other than that I suggest a search on a Marine forum. Removing the sticky mess could be a serious issue in getting anything to work in the current screw holes. One not so fun option is to drill out the screw holes oversize and put dowels in the holes.
Check www.loctiteproducts.com (http://www.loctiteproducts.com), go to the data sheet it will tell you what you need for your application.
Brass screw in a brass tube. And I think the no-name product must have been an el-cheapo from China.
When I am bored with nothing to do, I will disassemble, clean with rubbing alcohol, have a brewski and then re-assemble and apply honest-to-goodness Loctite.
