Great stuff, I use it on LOTS of screws.

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.

Works well on small 3-5mm screws

I use this stuff for my RC hobby. The screws are very small/fine thread screws ranging from 3mm-5mm with a few 6mm and 17mm for wheel nuts. I use this stuff on all metal to metal connections. It tends to stay a bit tacky for a long time, but eventually dries/hardens, which seems to take months. However, after installing and letting it sit for 24 hours, it does it's job well without making it impossible to remove the screws later. If it does hold too well later, using a soldering iron on the screw head to heat it up loosens the lock tight.

Prefer over the liquid stuff, nice dispensing bottle.

This blue thread-lock works well. The dispensing bottle is designed so that you can get exactly the right amount. When you're done, you can reverse the rotation on the bottle to suck it back in the bottle and save it. It's also thick so you don't waste any. With the liquid I put a blob on a piece of paper and dip the bolts into it. With this, you just put some at the tip of the dispenser, run the bolt on it and then use. No waste.

East to apply and measure out

East to apply and measure out just the right amount to apply to bolts/nuts. Doesn't drip out of the tube like the liquid. I just make sure after I've applied some to a bolt, to twist the cap back a little to suck the stuff back into the nozzle, so as not have any seep out while being stored. This Permatex thread locker gel lasts quite a while and won't dry out. Just be sure to put the lid back on after using to prevent drying out.

Good stuff

Permatex has figured out how to best transport their product. Liquid thread sealers can and usually are messy ( and sometimes hard to tell if the sealant is properly mixed). The glue stick stuff is nicer but is a bit stiff and clumpy. This gel is perfect transport method for threadlocker. No drips, no separation, no clumps, just a nice gel flow that sticks as needed. A nice feature is the ability to "unwind" the feed knob when you are done using it. Doing this "sucks" the gel back into the container, leaving no mess on the applicator tip. I have not tested the locking ability of this particular gel product however I have used the traditional Permatex medium threadlocker for many years with no issues. Good stuff.

Very good product. High recommendation.

This is my favored thread locker for scope mounting on rifles. It is a gel and stays nicely where placed. Never had a vibration loosening of the screws.Does not present a problem when removing screws to move or transfer. Very good product.

The gel is great for small parts assembly, like DIY drone kits.

I bought this for a teenage son to use when assembling a drone using small, metric, fine thread hex screws that tend to come loose in flight. The gel characteristic makes this a lot less messy to work with on these small parts and helps avoid over applying the product. So far, nothing has come loose that previously did when this product wasn't used, so it appears effective.

Works

Works good for locking your RC wheels nuts. The nozzle also makes it really easy for application to the wheel hub. Doesn't break your hand when you need it to come off either, just make sure before the first application to clean the hubs well.

Extremely easy to use!!!! A++

Easy to remove marked down because it is suppose to be medium hard to remove on purpose. Extremely easy to use. That is the best feature. Equal in quality to all similar products.

Great Product

I use this for mounting scopes on my rifles. Works Great.
