Slip-critical bolted joints will be used to join aluminum bridge deck sections by Reynolds Metals Company (RMC). To help ensure that a joint does not slip the proper bolt clamping force to achieve what is known as a friction connection must be determined. One method of achieving the proper clamping force is by "turn-of-nut" tightening. In this method a nut on a bolt clamping a joint together is rotated a specified amount, after first tightening the nut to a snug tight condition.
