Just wanted to give you a quick update on our acetal/delrin ACME leadnuts. They’re back in stock (we make batches so sometimes we in production)!
The standard ones are 16tpi for your Harbor Freight and similar Sieg X2 minimills. We are working on a 20tpi version for you Micromark and Little Machine Shop owners who have the 20 tpi version leadscrews. Unfortunately, due to the square and trapezoidal form threads, we can’t use a single point thread tool for all pitches. So, we’re making a 20tpi tap. Hang tight!
