I experienced this problem repeatedly _until_ I was introduced to this fantastic substance. Just a dab of it along the threads provides the necessary grip to discourage screws from loosening. All of your parts will still be there when you arrive at your destination. This works for everything that has screws and experiences vibration. Bicycle fender? Put some of this on the screws and the bike will rust into a hulk or get stolen before you have to worry about those screws coming out. Lawn blowers. Fans. It's quite versatile.
It's important to stress that this is a worthwhile product. Simply put, it's a watery colored glue. My first thought was "Can't I just use something else?". Sure you can, but it won't work as well. If you use anything stronger than this, that screw may never turn again. The necessary forces can just shear off the head of the screw. Less than ideal. Too thick and it won't follow the threads without applying it with a brush. If it doesn't follow the threads, it will come off and surround the screw head. Loctite Blue is in that 'Goldilocks' zone where it's just right.

The stuff really works. I use it mainly for making sure my gun sights, mounts, scope mounts, etc., are fastened securely and will not come loose from the vibrations and recoil when shooting. It has been doing an excellent job.
This is my first time using this type of product, but I must say - it's very easy to apply. I thought it would be more like a caulk or tooth paste, but it's more like a model glue. Goes on fast and dries in about 5 minutes. After about 10 runs, my tires stayed on and I am so happy.
What's even better - I needed to take off all my rims and without thinking I just put the nuts back on. After about 4 runs, I realized I didn't need to re-apply the thread lock - what was on there was still holding. I'll have to admit, not much pressure or vibration going on for a small 1/10 RC toy, but when a product works and works well - it not only deserves recognition - it's a product that I plan on keeping in my toolbox from now on.
All in all - this stuff works!
