Review on 💪 Loctite Threadlocker 242: Strong and Reliable Bond in a 50mL Blue Bottle! by Nale Dunn

It will hold but you can still loosen a bolt, nut or bolt. I don't know why they do this but it is BLUE Loctite even though it comes in a RED container. Blue holds bolts, nuts, screws, etc. in place, but you can still remove them with a little effort. The red version basically welds studs, nuts, screws or whatever in place forever. The only way to loosen the bolt is to melt it with heat.
