Technically, these bolts are supposed to be replace with new any time they are removed. They are coated with a 'microencapsulated' locking material, as are various other bolts throughout the car (caliper bolts for example). Locktite, properly applied, would probably serve the same purpose. Torque spec. listed in above post is pretty close. TDM calls for 115nm (X.72 to convert to ft#).
