Method for calculating Stud Bolt lengths

The Stud Bolt theoretical length can be calculated
by means of the formula: L = 2 (s + n + h + rf) + g

Method for calculating Stud Bolt length

  • s = free threads (equals 1/3 time bolt diameter)
  • n = nut height (equals nominal bolt diameter)
  • h = flange (plate) thickness
  • rf = height of raised face
  • g = gasket thickness
