Loctite? NO WAY! Hell, I grease the threads so I can remove the pins to allow a good cleaning of the pulley bearings and cage about once a year. Just a firm pinch on the allen key with two fingers is all you need. Like DMF says there's not much force on them so a few inch-lbs does the trick. If in doubt use less than you think it needs and check them after each ride to see if it comes loose. If it does pinch them tight a little harder until they don't come loose. I've found that most folks guess at too tight than too loose. If you want to get techincal you're looking for about 4 to 5 inch-pounds of torque for these. That's 4 to 5 pounds of force with one finger on the center and one an inch away. It's not much but it's enough.
