Pitch of bolt thread Solution

Follow our step by step solution on how to calculate Pitch of bolt thread?

FIRST Step Consider the formula

p b = \frac{d b - d c'}{1.22687}

Next Step Substitute values of Variables

∴

p b = \frac{10mm - 8.5mm}{1.22687}

Next Step Convert Units

∴

p b = \frac{0.01m - 0.0085m}{1.22687}

Next Step Prepare to Evaluate

∴

p b = \frac{0.01 - 0.0085}{1.22687}

Next Step Evaluate

∴

p b = 0.00122262342383464m

Next Step Convert to Output's Unit

∴

p b = 1.22262342383464mm

LAST Step Rounding Answer

∴

p b = 1.2226mm
