Did the job perfectly
Replacing axle nuts on my ‘06 Corvette. Locked them on the shaft easily. As recommended, waited 24 hours for the thread lock to set properly.

Awesome product.
This works again as advertised, i used it to install my V6 muzzle brake on my KSG and it worked great, that thing has not flinched a millimeter from when i first set it and it's been there for months and hundreds of rounds mostly slugs or 00 buck shot out of it, i think i've shot about 6 shells of birdshot in my life and not with this shotgun. It just works for weapons applications just make sure what you're using it for you're not intending to remove regularly cuz i would assume it would suck for you then, use the blue loctite instead which i have for regular bolts and such.
