This formula uses 4 Variables
Variables Used
Screw Pitch of Unified Nation Thread - (Measured in Meter) - Screw Pitch of Unified Nation Thread is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.
Pitch Diameter of Unified Nation Thread - (Measured in Meter) - Pitch Diameter of Unified Nation Thread is the diameter of the basic cylindrical shape on which threads are created.
Micrometer Reading Unified and National Thread - (Measured in Meter) - Micrometer reading Unified and national thread, is the reading of an instrument which can measure thickness of very small objects.
Wire Diameter of Unified Nation Thread - (Measured in Meter) - Wire Diameter of Unified Nation Thread is the diameter of the wire in thread measurements.
STEP 1: Convert Input(s) to Base Unit
Pitch Diameter of Unified Nation Thread: 6.98 Millimeter --> 0.00698 Meter (Check conversion here)
Micrometer Reading Unified and National Thread: 8.27 Millimeter --> 0.00827 Meter (Check conversion here)
Wire Diameter of Unified Nation Thread: 1.28 Millimeter --> 0.00128 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pun = (Dun-Mun+3*Gun)/0.86603 --> (0.00698-0.00827+3*0.00128)/0.86603
Evaluating ... ...
Pun = 0.00294447074581712
STEP 3: Convert Result to Output's Unit
0.00294447074581712 Meter -->2.94447074581712 Millimeter (Check conversion here)
FINAL ANSWER
2.94447074581712 2.944471 Millimeter <-- Screw Pitch of Unified Nation Thread
(Calculation completed in 00.004 seconds)

What is the use of Three wire method ?

The accurate measurement of thread pitch diameter, which may be perfect as to form and lead, presents certain difficulties which result in some uncertainty as to its true value. The adoption of a standard uniform practice in making such measurements is, therefore, desirable in order to reduce such uncertainty of measurement to a minimum. The “three – wire method” of measuring thread pitch diameter, has been found to be the most generally satisfactory method when properly carried out, and is recommended for universal use in the direct measurement of thread plug and thread setting plug gauges.

How to Calculate Pitch of Screw Threads?

Pitch of Screw Threads calculator uses Screw Pitch of Unified Nation Thread = (Pitch Diameter of Unified Nation Thread-Micrometer Reading Unified and National Thread+3*Wire Diameter of Unified Nation Thread)/0.86603 to calculate the Screw Pitch of Unified Nation Thread, 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 of Unified Nation Thread is denoted by Pun symbol.
