Learning to ride on gravel

As I was close to finishing my hour of practice yesterday, I noticed on my 26” Nimbus muni the left side crank bolt was very loose. I came onto it pretty hard with the allan key to tighten it. Today after almost an hour it had backed off again. So Here are a few questions, Is there a torque setting I should put to it. Is just tightening it with the allan key and some blue loctite the way to go? Any thoughts why this happened and what is a good way to prevent it from reoccurring? Thanks

From this thread: “Use a torque wrench and take it up to 25 lbs. They should stay tight. Make sure the threads are clean, and use blue Loctite.”

Also if the ISIS spacers are too thick there could be some looseness in the spline and that would tend to loosen the bolt.
