Loctite 680 442-68015 10ml Retaining Compound, High Strength and Viscosity, Green Color

I don't know what is in this product, but it works like magic on metal and plastic surfaces. Dries very quickly for easy repairs. A must have for your workshop. Works on steel, brass, plastic, etc. Produces a very strong bond and is very easy to apply. It is particularly helpful for repairs on antique clocks for situations like loose governor fly wheels. The bond has never failed even once over many different repairs.

I used it to fix a Campagnolo BB30 cup set into my bicycle frame. Since I applied it, the BB has beed dead silent. A dead silent BB30 is practically a miracle and deserves even more than 5 stars. 1 million stars.

Seems pricey but it worked great as a bearing retainer on a JD mower deck repair. I used it on both the top and bottom bearings. Six total. saved me buying new spindles. Initially thought of using the old soda or pop can shim. Well worth it. Bearings from fastenal. Blades and a belt from Amazon as well. Blades all cut even now.

This stuff is magical. Bought it because a press fit for my senior design project accidentally got machined as a slip fit. The bearings i had needed some axial preload on them so i put some of this stuff on the shaft, clamped it down for an hour, and its been holding strong since.I will definitely keep this in mind as a replacement for tight machine tolerances.

I used the Loctite to be my barrel extension of an AR-15 to the Upper Receiver. I had approximately had a 0.002-0.003 clearance between the 2 parts. It was easier to work with than the Red Loctite versions because it wasn't as runny. I then installed the barrel nut and let set. The next I took the barrel nut off to confirm it worked. I could move the barrel or wiggle it at all. It had filled in the gap just as expected.
