How are threaded inserts measured?
Modern threaded plastic inserts are stipulated by a measurement of the outer diameter (OD), which is measured over the pipe thread in the case of a male pipe. To be sure that the pipe thread will match, threads per inch (TPI) are also measured. The inner diameter (ID) is sometimes used when buying PVC pipes.
Why is ACME thread 29 degrees?
The Acme thread form has a 29° thread angle with a thread height half of the pitch; the apex (or crest) and valley (or root) are flat. This shape is easier to machine (faster cutting, longer tool life) than a square thread.

THINBIT, manufactured by Kaiser Tool Co., announced the expansion of its GROOVE ‘N TURN line with ACME THREADING inserts. The inserts are designed to cut thread sizes 4, 5, 6, 8, 10, 12, 14 and 16 threads per inch. Tools have geometry to cut standard 29° acme thread profiles. Inserts can be used to cut centralizing or stub profiles by overcutting.
What thread sizes do the inserts cut?
The inserts are designed to cut thread sizes 4, 5, 6, 8, 10, 12, 14 and 16 threads per inch. Tools have geometry to cut standard 29° acme thread profiles. Inserts can be used to cut centralizing or stub profiles by overcutting. The inserts can be used for internal acme threads on parts with bore diameters of 1.250″ and larger.
