WebMay 12, 2024 · BOLT TENSIONING EXAMPLE: Let’s say your target is 50,000 psi bolt stress. First you need to consult with the tensioner and the engineer to make sure you have all your load loss factors figured out. But for this example, you’re going to tension your A pass 20% above what you would do your B pass. Your B pass is your final bolt load. WebTable 1.
