Loctite 29021 Green 290 Medium High-Strength Threadlocker, 300 Degree F Maximum Temperature, 10 mL Bottle

Works great!

Unlike other threadlocker products, Loctite 290 green works by penetrating into assembled fasteners by capillary action. This allows you to completely assemble your workpiece without worrying about a threadlocker setting before you have everything adjusted and torqued to the desired state. Its thin and runny, and seems to contain more volatile organics than other versions of Loctite. This is for metal-to-metal connections. Your fasteners must be clean and dry, and free of oil and grease. I am very pleased with the utility and performance of this product, and of the entire family of Loctite threadlockers. As noted by another reviewer, the illustration is incorrect. This is for a 10 ml bottle, which for a casual user like me will last for several years.

Worked as expected

very tough to get apart, but still possible.
