Radius of Root of Threads Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radius of Root of Thread = 0.137329*Pitch of Threads
r = 0.137329*p
This formula uses 2 Variables

Variables Used

Radius of Root of Thread - (Measured in Meter) - The Radius of Root of Thread is defined as the radius of the circle touching the root of the screw threads and its center is at the bolt center.
Pitch of Threads - (Measured in Meter) - Pitch of Threads is the distance between two adjacent threads on a screw, bolt or nut.

STEP 1: Convert Input(s) to Base Unit

Pitch of Threads: 3.99 Millimeter --> 0.00399 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r = 0.137329*p --> 0.137329*0.00399

Evaluating ... ...

r = 0.00054794271
