Permatex 24010 Medium Strength Threadlocker Blue Gel, 10 g Gel Twist Applicator

Expensive, but excellent and long-lasting. Closely monitor the package, however, the turning part is easly broken and the product package tends to weep out the contents

This stuff is amazing. I work on computers a lot and often see small amounts of blue threadlocker painted on precision screws in laptops - particularly Apple computers. I had a lot of customers with missing screws from the bottom of their aging MacBooks so I started keeping spares with my screwdrivers, but I noticed the new ones also came with blue threadlocker on them so I decided to buy some myself and try it out. The gel tube seemed like the least messy way to use it so I bought a tube, now I use it for EVERYTHING including laptop screen hinge screws, bottom case screws, bicycle component bolts, suspension parts on my car, the shower handle that keeps coming loose - you name it I'll put threadlocker on there because it works. My bicycle handlebars start to vibrate loose one night riding down a large hill, so I tightened up the loose bolts when I stopped. As soon as I got home I took the bolts out and reinstalled with threadlocker. Now I can be sure I won't have to worry about them wiggling loose again. I keep a twist tube of blue threadlocker with my precision screwdrivers for this and all other screws I don't want to come undone due to vibration. It can be a little messy, but here's what works best for me: Usually I put a strong magnet on the screwdriver first Then I put the screw on the tip of the driver Then I twist out a tiny bit of threadlocker and stick the tip of the screw into using the screwdriver as a handle And finally install the screw A bit of blue threadlocker usually squeezes out of the threads and builds up around the screw head, if it's not too much I just leave it there. I try not to touch the threadlocker with my fingers since it's sticky and will get everywhere. Even if you can't see it, your fingers will make everything very sticky, so I use it sparingly and try not to get it on my skin.

good stuff........ Dont waste as much as with the other regular stuff. easier to control how much comes out

Best in the business for a reason. Love this stuff.
