WebCalculation notes on using Hydraulic bolt tensioning tools. Formula to use: Residual Bolt Load = Bolt Stress x Bolt Tensile Stress Area Units: Residual Bolt Load = (N or Tons) Bolt Tensile Stress Area = (mm2 or In2) Below are tables of standard ISO Metric and Imperial Thread forms along with WebFeb 4, 2024 · With tensioning, you’re typically going to see +/- 10% accuracy. That means your bolt scatter will be lower. If the target was 50 KSI, you’d see values between 45-55 KSI. However, there are some important caveats to note here. First, tensioning is more expensive and more complicated than torquing. WebNote: In over thirty years of job site experience, match marking is rarely seen being properly performed, let alone continuous inspection for initial snug tightening. If turn-of-nut was applied properly, commencing, as it should, from some initial bolt tension, the bolts are usually taken to beyond their yield point. dr abd rani osman
