Method for calculating Stud Bolt length


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



The height of a nut for a Stud Bolt is the same as the diameter of the thread rod



Studs are measured parallel to the axis (L) from the first to the thread without the chamfers (points). S = free threads equals 1/3 time bolt dia

Hex bolts are measured from under the head to the top of de bolt
