Thread Pitch Vs Thread Count

Thread Count

When people want quality Acme threaded products, we’re the company that delivers. From Acme screws to Acme nuts, our company has the threaded products people utilize in a variety of applications everyday. We have Acme screw threads from ⅜” to 2.5” in diameter.

In America, fasteners are measured by their TPI: threads per inch. It’s a simple count of the number of threads per inch measured along the length of the fastener. For those who use the metric system of measurement, the terminology is “thread pitch.”

The smaller the fastener, the finer the threads. So, smaller fasteners often have higher thread counts than larger ones.

Now about thread pitch: it’s the distance between threads expressed in millimeters as measured along the length of the fastener. If you were in England, thread pitch would be used; in America, it’s TPI: threads per inch.

Whether it’s thread count or pitch, either way a thread gauge is used to do the actual measurement. This is a handy tool that can be purchased inexpensively if needed.

Here at Dependable Acme, we offer a thread profile guide to confirm your “TPI” requirements. You can download a printable PDF version on our website; this guide helps you measure threads from 2 to 12 threads per inch.

We also have a page devoted to our Acme general purpose 2G thread series limiting dimensions and tolerances. You can use these dimensions to determine the diameter along with the thread pitch.
