The Importance of TPI When Selecting a Fastener For Your Machine

Are you looking for the right fasteners for a particular project? There are myriad factors you’ll need to consider. For example, you’ll need to think about what diameter you need your fasteners to be. You’ll also need to spend some time thinking about what materials the fasteners should be made out of. But one of the most important factors is going to be what’s known as TPI.

An Overview of TPI

If you purchase fasteners all the time, you’re probably well aware of what TPI is. But if not, TPI isn’t all that difficult to understand. TPI stands for “threads per inch,” it refers to, as its name would suggest, the number of threads that are on a fastener for every inch. You can usually count the TPI of fasteners for yourself as long as there aren’t too many of them.

Generally speaking, smaller fasteners often have finer threads on them, while larger fasteners have threads that are more spread out. But this isn’t always the case. There are also some larger fasteners that have finer threads on them to improve their overall strength. It’s why it’s essential for you to pay attention to TPI when choosing fasteners.

There are times when you may see what’s called thread pitch listed for fasteners instead of TPI. Rather than referring to the number of threads within an inch, thread pitch refers to the distance that exists between two threads. This measurement can be used to calculate the TPI of a fastener if you want.
