how much torque do u put on a stud? i heard 15 ft. lbs. that is not alot. what hapens when u over torque. i have a motormaster electric impact that goes to 1050 in. lbs, witch is around 87ft lbs. last time i have used a air ratchet, and went to the gun almost gave out. over 1000 studs and never one came loose until now. i use lock tight. i see some are coming loose, so i bought heaver nuts, and i am going to do all the studs over with red lock tight, but i wonder about torque?
