STEP 0: Pre-Calculation Summary

Formula Used

Change in External Load = Resultant Load on Bolt-Initial Preload in Bolt Due to Tightening of Nut
ΔP_i = P_b-P_i
This formula uses 3 Variables

Variables Used

Change in External Load - (Measured in Newton) - Change in External Load is the amount of variation in the externally applied force or load.
Resultant Load on Bolt - (Measured in Newton) - Resultant Load on Bolt is the total resultant force/load acting on the bolt after tightening the bolt.
Initial Preload in Bolt Due to Tightening of Nut - (Measured in Newton) - Initial Preload in Bolt Due to Tightening of Nut is defined as the difference between the resultant load on the bolt and change in external load.

STEP 1: Convert Input(s) to Base Unit

What is a fastener?

A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.
