If the 1/2" bolts have three tick marks on the heads, they are Grade 5 bolts, 75 ft lbs, and if there are five tick marks on the heads, they are Grade 8 bolts, 107 ft lbs. These torques are for plain bolts completely dry, no lubricant on the threads. If the nuts are flange style, apply torque to the bolt, not the nut.
