Blue and Red are the most common threadlockers that we all use on our hot rods and race cars. There are other colors, but the reality is that those are actually categorized as retaining compounds which are WAY stronger. But how does Red and Blue threadlocker actually work? Does there need to be torque applied? Or is it just pretty colored glue? I always figured it was more than a glue, but maybe not.
If you aren’t familiar with threadlockers for some reason, they are applied to nuts and bolts in applications where vibration and load may increase the chance for a fastener to come loose. While I don’t usually use threadlocker on a fastener that has some kind of lock washer or lock nut, I know people that do in race applications with ultra high vibration and stress.
But the beauty of threadlocker is that they are very easy to use, simple, and effective.
In the video below you’ll see how they work, hear about some comments in previous videos that said they weren’t being used correctly, and then even more testing. Check it out.
