Core Diameter of Bolt given Pitch Solution

STEP 0: Pre-Calculation Summary

Formula Used

Core Diameter of Threaded Bolt = Nominal Diameter of Threaded Bolt-(1.22687*Pitch of Bolt Threads)
d_c' = d_b-(1.22687*p_b)
This formula uses 3 Variables

Variables Used

Core Diameter of Threaded Bolt - (Measured in Meter) - Core Diameter of Threaded Bolt is defined as the smallest diameter of the thread of the bolt. The term “minor diameter” replaces the term “core diameter” as applied to the thread.
Nominal Diameter of Threaded Bolt - (Measured in Meter) - Nominal Diameter of Threaded Bolt is the diameter equal to the external diameter of the threads or the overall diameter of the bolt.
Pitch of Bolt Threads - (Measured in Meter) - Pitch of Bolt Threads is the distance between two adjacent threads on a bolt.

STEP 1: Convert Input(s) to Base Unit

Nominal Diameter of Threaded Bolt: 10 Millimeter --> 0.01 Meter (Check conversion here)
Pitch of Bolt Threads: 1.25 Millimeter --> 0.00125 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_c' = d_b-(1.22687*p_b) --> 0.01-(1.22687*0.00125)

Evaluating ... ...

d_c' = 0.0084664125

STEP 3: Convert Result to Output's Unit

0.0084664125 Meter -->8.4664125 Millimeter (Check conversion here)

FINAL ANSWER

8.4664125 ≈ 8.466412 Millimeter <-- Core Diameter of Threaded Bolt

(Calculation completed in 00.004 seconds)

What is a fastener?

A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.
