The factory torque spec requires a new bolt. Do not do the 90 degrees on a used bolt.

If using a used bolt, then limit torque to 55ft-lbs (from calculation based on bolt size and grade). I use anti-seize on the thread and a small dab between head and washer.

Most torque values are "dry" values. Personally I re-use all the bolts and torque to value spec. I do not + deg the used bolts. Also on bolts that rarely get removed or high stress areas I applied a small dab of Loctite 242
