Warning about LocTite

Thank you! Finally somebody mentioned Loc-Tite! It's a revolutionary thing, really. Just a little bottle of stuff is all it is. For temporary use (when you want to be able to remove the screw later), I recommend Blue Loc-Tite. There are stronger ones, but those are more of sealants, like for CO2 bottles (red or green LT). So go pick up a bottle of this stuff at your hardware store. It's great!

Loc-Tite is the brand. Thread-Loc is the product. Blue is (I think) No. 242 and used for items needing only hand tools to unscrew. No. 272(?) makes for a tighter seal requiring heavier tools for removal. The other seals are for slip-in non-threaded connections. To be sure, look at the back panel of the packaging - there should be a table of comparisons there.

This is actually already an old product. It works by filling in the gaps and spaces between the threads, and when hardened keeps the parts from moving/shaking/jarring loose. It's not a glue.

A few words of advice on the use of Thread-Loc; Use it very sparingly around the plastic portions of your guns. The chemical compounds, when used excessively, will eat away at the plastic and cause it to become brittle and crack away. Furthermore, when you look at the cracks, you'll see that they've been 'welded' from the inside-out, and cannot be glued back together, due to a change in the plastic at the joint.

This comes after I used Thread-Loc to secure the pin in the magazines of my MP5 and used a bit too much. The tops of the magazines cracked where they come in contact with the AEG housing and have gradually faded away - from the underside.

Next time, I'll use superglue. The stuff works great on metal-to-metal contact, but avoid it's use around any of the plastics.

BTW, the fumes given off by the blue Thread-Loc are just as caustic to the plastic as direct application... -LD
