All your fastener needs from a single source Inch and metric thread pitch charts Inch & Metric Thread Standards Visit our online store for product availability Inch and metric thread sizes are specified differently. Inch thread sizes are specified by the nominal major diameter and the number of ...
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. Coarse thread is benefic...
Thread Pitch Gauge:Used to measure the amount of threads per inch, as well as the thread to thread spacing in metric applications.Accurate measurement of threadsBefore you start measuring the threads of your fluid pipe or tube, ensure that they are in good conditions. Distorted or worn out ...

p = pitch = 1 ÷ number of threads per inch.Form of Thread: The angle between the sides of the thread is 60 degrees when measured in an axial plane, and the line bisecting this angle is perpendicular to the axis. The depth of the truncated thread is based on factors entering into the...
a 4G5G bolt would have a grade 4 pitch internal thread and a grade 4 crest internal thread. When the pitch and crest grades are the same, the notation is simplified; a 4G4G bolt would be labeled 4G instead. Threads with higher tolerance install quicker and are better-suited to accommodate...

pitch or the term for the number of threads per inch of screw length. This number determines how coarse (e.g., fewer threads per inch) or fine (e.g., more threads per inch) the thread pitch is. Screws must be used in holes with matching pitches, or the parts will not fit ...
Use a thread pitch gauge to determine the number of threads per inch or the distance between threads in metric connections. Place the gauge on the threads until the fit is snug, and then match the measurements to the accompanying chart. Video Resources and Guides Thread Pitch and Size- Courte...
