Threadlocker + Retaining Compound

Pedal axles, chainring bolts and stem clamps work themselves loose under constant vibration, and no torque wrench stops that. Medium strength threadlocker is the normal choice on a bike: it holds the joint and still comes apart with hand tools. High strength belongs only where nothing is ever dismantled again, and retaining compounds go between a bearing and its seat, not into a thread. The colour tells you the grade: purple low strength, blue medium, green high.
