Turn-Of-NutAlternative Design BoltsWasher ControlCalibrated Wrench MethodThis method involves tightening the fastener to a low initial "snug tight" condition and then applying a prescribed amount of turn to develop the required preload. The actual preload will depend on how far the nut is turned as well as how much preload was established prior to the turning. 1. Snug the joint to bring the assembly into firm contact. Apply a few impacts with impact wrench until solid sound or apply full effort with a spud wrench. 2. Inspect the joint to verify "snug tight". 3. Match mark bearing face of the nuFasteners Bolt Grades, Strength & MaterialsIf a bolt is stainless steel, we recommend replacing with stainless steel. Furthermore, if a bolt grade is 316 stainless, prized for extra corrosion resistance, we always recommend using 316 when replacing and not a lesser bolt grade such as 304 or 303.Grade A Bolts McMaster-CarrAbout Hex Head Screws and Bolts.
