You may not realize it, but anaerobic adhesives (glue that cures in the absence of air) can be tailored for many different situations. This Loctite product is meant to penetrate fastener threads that are already tightened down. It wicks very well into the enclosed thread surface then hardens. Another characteristic of these adhesives is that they have both a break away torque and a prevailing torque. That is, it takes one level of force to break the bond and another to continue to thread the fastener. You want the breakaway torque to be nearly as strong as the fastener to keep the fastener holding the assembly tight against cycles, wear, and vibration. If too high, you will have to break the fastener to remove it. The prevailing torque will dictate how difficult the removal will be but also allow the joint to remain intact with a slower total loss. This adhesive is only for medium and large fasteners. Small fasteners are too weak to absorb the breakaway torque.FYI, I thought it was too strong but tested it anyway on a pin hinge on the back of a broach. Those pesky fasteners tend to swing open when not desired, leading to loss of the jewelry. I hoped I could break the joint after curing, leaving the prevailing torque to provide some resistance to rotating. It was, as suspected, too strong for those tiny pivot joints in jewelry pins. No, I didn't damage the broach, I bought a box of pins from a craft store to experiment upon. The best solution so far is to squeeze the pivot with a pair of plier to create physical reduction of the clearance between the parts of the hinge.
