I always have locktite around, and also anti seize compound when working on my car. Use anti seize whenever steel bolts go into aluminum parts. (Most of the dang car!). Prevents galling of threads later. I learned about threads and bolts in the navy, (submarines), where it is against procedure to assemble parts without a lubricant on the threads, in critical systems. So I follow this on my car. May be overkill, but hey....
