Does exactly what it should. I use it for locking the pivot screws on knives that I've been fettling. I have also used in the past on just about everything that bolts on to a motorcycle.
The excess air in the tube is needed because it is an anaerobic setting compound - it starts to set when the air (O²) is squeezed out from between the threads of whatever you are locking.

I've successully used this in the past to hold small grub screws on bathroom fittings in place. True you don't get much in a tube, but you do not need to use much on a screw either. It's glue and glue goes off quickly rendering it useless.

Think when you've wasted money on a tube of silicon, or one of the no-mails glues. You only wanted to use a little, then you stick it in the tool box only to find it unuseable next time you go to it in a month. Same principle.

The first time i ordered this item: It arrived, but leaked every where when I opened the packet. Blue every where!!! Not from the nozzle, but from the bottom of the tube. Luckily it wipes off your hands, using wet wipes.

I suspect the leak happened because in the warehouse they used a stanley knife or something similar to open a larger box.

Anyhow, i had a replacement sent. This time no leaks. The liquid is blue, clearly identifiable. Dab a little on a screw, screw it tight and voila, it is fixed in place. It should not unravel/work itself loose from vibrations etc. It is not glued tight, which means you can still undo the screw with a screw driver.

Where did i use this: the tiny screws on the bottom of my macbook pro, keeping them in place. AND on the screws on my bike stem, preventing them from working loose.

Very handy for those sensitive bolts, e.g. on motorcycle suspension or sprocket/disc bolts. The tube is a little small though, I would probably look at getting a solid stick next time. But handy to have in your tool kit none the less.

An invaluable tool for somebody that builds multirotors, I use it on any metal-to-metal joint & it really adds peace of mind when flying & I've not lost any bolts since starting to use it on my builds. It's expensive for the size/amount that you get, but each bolt only needs a tiny dab so this little tube will last hundreds of applications.

I got this for the draw handles on my Wife's desk.The drawers on the desk are open and shut quite often. The customised handle holding screws have a habit of coming undone despite being done up tight. I put the locktite on the screws following the instructions. After a few days of use they were undone again. After several repeat applications over a period of weeks it had still did not solved the problem. I am loath to apply a more permanent type to glue, such as Araldite but it's starting to look as though I might have to.

I am familiar with Loctite from the engineering days of the 70's when I worked a massive mechanical manufacturing plant and pleased to say the product is still the same reliable quality it was and the small size tube makes it ideal and affordable for the average DIY person. Fixed the nut on my bike pedal crank with it and now it doesn't work loose.

I used tock 'n' seal to secure the assembly of a toilet seat and it worked in less than 30 minutes. This is ideal for jobs around the house. As a tip, I would only buy it as you need it rather than having it stored around the house as it can go off.
