Nominal Diameter of Bolt Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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

Core Diameter of Threaded Bolt: 8.5 Millimeter --> 0.0085 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_b = d_c'+(1.22687*p_b) --> 0.0085+(1.22687*0.00125)

Evaluating ... ...

d_b = 0.0100335875

STEP 3: Convert Result to Output's Unit

0.0100335875 Meter -->10.0335875 Millimeter (Check conversion here)

FINAL ANSWER

10.0335875 ≈ 10.03359 Millimeter <-- Nominal Diameter of Threaded Bolt

(Calculation completed in 00.004 seconds)
