A screw’s thread pitch plays an important role in its holding power. Screws with a fine thread pitch typically have greater holding power than those with a coarser thread pitch. What is thread pitch exactly, and how does it affect a screw’s holding power?<\/p>\n\n\n\n

What Is Thread Pitch?<\/h2>\n\n\n\n

Thread pitch is the distance between the threads on a screw. All screws have threads. Consisting of helical ridges, they allow screws to be driven into objects. As you press and turn a screw against an object, the threads will dig into the object while simultaneously scooping out material. The distance between a screw’s individual threads, however, varies depending on the thread pitch.<\/p>\n\n\n\n

Metric vs U.S. Thread Pitch<\/h2>\n\n\n\n

In metric screws, thread pitch is measured in millimeters. It’s not uncommon for metric screws to have a thread pitch of 1.5 to 1.25 millimeters, meaning the distance between the individual threads are 1.5 to 1.25 millimeters.<\/p>\n\n\n\n

In U.S. screws, thread pitch is measured in threads per inch (TPI). As the name suggests, TPI represents the total number of threads per inch. Some U.S. screws have a TPI of 20, whereas others have a TPI or 25 or higher. <\/p>\n\n\n\n

Gripping Objects<\/h2>\n\n\n\n

Thread pitch will affect a screw’s ability to grip objects. A fine thread pitch will result in more points of contact. As a result, the screw will create more friction and have a better grip on the object. A coarse thread pitch, on the other hand, will result in fewer points of contact but deeper grooves. This can make coarse screws a good choice for soft materials, such as wood.<\/p>\n\n\n\n

Resistance to Loosening<\/h2>\n\n\n\n

Screws with a fine thread pitch are better protected from loosening. They are able to distribute the force across more points of contact. Therefore, screws with a fine thread pitch are harder to pull out and more resistant to loosening than those with a coarse thread pitch.<\/p>\n\n\n\n

Shear Strength<\/h2>\n\n\n\n

A fine thread pitch translates into greater shear strength. Screws with a fine thread pitch have a larger minor diameter than those with a coarse thread pitch. This design translates into greater shear strength, which improves the screws’ holding power.<\/p>\n\n\n\n

In Conclusion<\/h2>\n\n\n\n

Always check the thread pitch when shopping for screws. It represents the distance between a screw’s threads. Some screws have a fine thread pitch, whereas others have a coarse thread pitch. Regardless, it will influence their ability to grip objects, resistance to loosening and shear strength.<\/p>\n","protected":false},"excerpt":{"rendered":"
