Thread Pitch Chart Thread Pitch ChartThread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coars...
Manufacturers use identifiers such as ASME B1 .1 and ISO 261, to classify the main thread characteristics: pitch, angle, diameter, and form. Some organizations that are developing these, are the International Organization for Standardization, SAE International, British Association, and Deutsches Institu...

UNR Threads The UNR thread is a modified version of a standard UN thread. The single difference is a mandatory root radius with limits of 0.108 to 0.144 times the thread pitch. When first introduced decades ago, it was necessary to specify UNR (rounded root) threads. Today, all fasteners ...
Pitch Refer to the diagram to see how thread pitch is measured: Lead Lead is the linear travel the nut makes per one screw revolution. Lead is basically Pitch * Thread Starts. Lead Angle The lead angle is the helix angle of the thread based on the lead distance. Multi-start threads have...
