In some titanium screws threads, we can see blue glue, red glue, yellow glue and so on. The main role of the glue is to prevent loose, and need choose suitable glue according to the application of your screw.

Usually we have two kinds of glue: Nylon glue and chemical glue. If the titanium screws need to be removed often, then you need to choose nylon glue, if the titanium screws do not need to be removed often, or after the assembly is not removed, then choose chemical glue. If the chemical glue is often removed, the anti-loosening performance will be reduced, and the original effect is not so good.
