Crank arm working loose

I have a problem with the non drive side crank arm on my Commencal Normal Disc. It's the stock FSA crank set. On nearly every recent ride the allen head nut in the non drive side arm is working itself loose and I have no idea why. Anyone got any ideas as to why this is happening?

Usually due to the crank arm squirming on the taper.
Torque correctly and use some loctite.0 -
Okay, i tried some locktite on it but it still works loose whilst riding. It's driving me insane! Any other ideas on the cause/how to stop it?My Bikes And Me

Probably worn out by now. Need a new crank.0

if its a powerspline type-once you have over tightened it becomes knackerd basically.
get a hollowtech type system, they are much better.Dont look at it-ride it! they are tools not f*cking ornaments

so what is the crank set?
and Allen headed NUT never seen any of those on cranks.
the Bolt maybe?"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

if it's a square taper and has worked loose a few times the crank arm's square faces will have worn and you need a new crank arm
