Pitch of Screw Threads Solution

Follow our step by step solution on how to calculate Pitch of Screw Threads?

FIRST Step Consider the formula

P = \frac{D - M + 3 \cdot G}{0.86603}

Next Step Substitute values of Variables

∴

P = \frac{7mm - 8.2mm + 3 \cdot 1.2mm}{0.86603}

Next Step Convert Units

∴

P = \frac{0.007m - 0.0082m + 3 \cdot 0.0012m}{0.86603}

Next Step Prepare to Evaluate

∴

P = \frac{0.007 - 0.0082 + 3 \cdot 0.0012}{0.86603}

Next Step Evaluate

∴

P = 0.00277126658429846m

Next Step Convert to Output's Unit

∴

P = 2.77126658429846mm

LAST Step Rounding Answer

∴

P = 2.7713mm

How to Evaluate Pitch of Screw Threads?

Pitch of Screw Threads evaluator uses Screw Pitch = (Pitch Diameter-Micrometer Reading+3*Wire Diameter)/0.86603 to evaluate the Screw Pitch, The Pitch of Screw Threads formula is defined as the distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis of the thread. It is represented by the letter p. (p=1/n). Screw Pitch is denoted by P symbol.
