1/2 PVC threaded nut

thingiverse

You will need a nut for threaded PVC pipe. I purchased one designed for half inch. The thread pitch is set to 1.8, which approximates 14 threads per inch quite well. It fits into the threaded riser pipes for sprinklers that are readily available in short lengths, ranging from 1 to 4 feet, suitable for constructing small structures. This nut also fits the numerous PVC connectors available on the market. To confirm thread pitches and diameters for various PVC sizes, refer to this table at harvel.com. Additionally, you can convert SAE to metric threads using mdmetric.com. Note that a 3/4 inch nut uses the same 1.8 thread pitch because it shares the same thread type. The design file may be significantly reduced in size by utilizing a higher resolution number.
