Nominal Diameter of Bolt Solution

Follow our step by step solution on how to calculate Nominal Diameter of Bolt?

FIRST Step Consider the formula

d b = d c' + (1.22687 \cdot p b)

Next Step Substitute values of Variables

∴

d b = 8.5mm + (1.22687 \cdot 1.25mm)

Next Step Convert Units

∴

d b = 0.0085m + (1.22687 \cdot 0.0012m)

Next Step Prepare to Evaluate

∴

d b = 0.0085 + (1.22687 \cdot 0.0012)

Next Step Evaluate

∴

d b = 0.0100335875m

Next Step Convert to Output's Unit

∴

d b = 10.0335875mm

LAST Step Rounding Answer

∴

d b = 10.0336mm
