How to determine screw thread count
WebStandards bodies have spent immense effort classifying thread pitch because it determines the thread tensile stress area, which can be discovered with this equation. The stress is correlated to the TPI of the bolt. As= π/4 X (D - (.938194 X p))² Where: As : tensile stress area D : bolt diameter p : 1/threads per inch (TPI) WebJul 23, 2024 · TPI is a term used to help identify how many threads are in an inch. To determine treads per inch an inch of the bolt is measured and then the peaks on the …

WebJan 8, 2024 · The effective area of the thread is roughly 80% of thread OD less root dia. When you divide this thread effective area into the area the material said you need to equal the screws root strength, you get how many threads are required. That number of threads required times the pitch gives the depth required.
