Loctite290 Threadlocker for Automotive Pre-Assembled Fasteners: Medium-Strength, High-Temp, Anaerobic, Works on All Metals | Green, 6 ml Tube (PN: 37423-487234)

This thread locker works very good on assembled parts, I use it on bolts and nuts.

I am much appreciated for quick delivery of this quality item.

Have used this stuff for a long time ant it works great.

Used for retaining the small screws in eyeglasses.

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.

Not much to say. This is exactly what I was looking for,and I received it in short order in good condition

Good purchase

We use it to secure a number of screws in one of our repair units. Works fine.
