Nominal Diameter of Bolt given Wrench Torque Solution

STEP 0: Pre-Calculation Summary

Formula Used

Nominal Bolt Diameter = Wrench Torque for Bolt Tightening/(0.2*Pre Load in Bolt)
d = M_t/(0.2*P_i)
This formula uses 3 Variables

Variables Used

Nominal Bolt Diameter - (Measured in Meter) - Nominal Bolt Diameter is the diameter equal to the external diameter of the threads or the overall diameter of the part of the bolt.
Wrench Torque for Bolt Tightening - (Measured in Newton Meter) - Wrench Torque for Bolt Tightening is defined as the torque required to create a load on fasteners such as a nut, bolt, or lag screw.
Pre Load in Bolt - (Measured in Newton) - Pre Load in Bolt is the tension created in a bolt when it is tightened.

STEP 1: Convert Input(s) to Base Unit

Wrench Torque for Bolt Tightening: 49500 Newton Millimeter --> 49.5 Newton Meter (Check conversion here)
Pre Load in Bolt: 16500 Newton --> 16500 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d = M_t/(0.2*P_i) --> 49.5/(0.2*16500)

Evaluating ... ...

d = 0.015

STEP 3: Convert Result to Output's Unit

0.015 Meter -->15 Millimeter (Check conversion here)

FINAL ANSWER

15 Millimeter <-- Nominal Bolt Diameter

What is nominal diameter?

Nominal Diameter is defined as the largest diameter of the screw .It is also called major diameter. The size most commonly associated with screw threads is the nominal diameter. Nominal diameter is a more of a label than a size. For example, a bolt and nut may be described as being ½” diameter. But neither the external threads of the bolt nor the internal threads of the nut are exactly .

How to Calculate Nominal Diameter of Bolt given Wrench Torque?

Nominal Diameter of Bolt given Wrench Torque calculator uses Nominal Bolt Diameter = Wrench Torque for Bolt Tightening/(0.2*Pre Load in Bolt) to calculate the Nominal Bolt Diameter, Nominal Diameter of Bolt given Wrench Torque is defined as the size most commonly associated with screw threads is the nominal diameter. The nominal diameter is more of a label than a size. Nominal Bolt Diameter is denoted by d symbol.

How to calculate Nominal Diameter of Bolt given Wrench Torque using this online calculator? To use this online calculator for Nominal Diameter of Bolt given Wrench Torque, enter Wrench Torque for Bolt Tightening (M_t) & Pre Load in Bolt (P_i) and hit the calculate button. Here is how the Nominal Diameter of Bolt given Wrench Torque calculation can be explained with given input values -> 15000 = 49.5/(0.2*16500).

FAQ

What is Nominal Diameter of Bolt given Wrench Torque?
