Pitch of bolt thread Solution

STEP 0: Pre-Calculation Summary
Formula Used
Pitch of bolt threads = (Nominal Diameter of Threaded Bolt-Core Diameter of Threaded Bolt)/1.22687
pbt = (db-dc')/1.22687
This formula uses 3 Variables
Variables Used
Pitch of bolt threads - (Measured in Meter) - Pitch of bolt threads is the distance between two adjacent threads on a bolt.
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.
STEP 1: Convert Input(s) to Base Unit
Nominal Diameter of Threaded Bolt: 10 Millimeter --> 0.01 Meter (Check conversion here)
Core Diameter of Threaded Bolt: 8.5 Millimeter --> 0.0085 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pbt = (db-dc')/1.22687 --> (0.01-0.0085)/1.22687
Evaluating ... ...
pbt = 0.00122262342383464
STEP 3: Convert Result to Output's Unit
0.00122262342383464 Meter -->1.22262342383464 Millimeter (Check conversion here)
FINAL ANSWER
1.22262342383464 1.222623 Millimeter <-- Pitch of bolt threads
