Method for calculating Stud Bolt length

The Stud Bolt theoretical length can be calculated

by means of the formula:

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
