Stock size for external threads

3 Jul 2018 An external thread, also known as a screw thread, is cut by hand with a round die which is fixed in a die stock. Round dies have three or more cutting edges, depending on their size. Between these cutting edges there are  IRWIN® HANSON® has been manufacturing High Carbon Steel threading tools Tap size and recommended drill bit size are laser-etched on each tool for eas Die Stock: Drives 1” Hex Dies With And Without Alignment, Accepts Sm & Med. 13M standard.

Unless you are using pprecision ground stock such as drill rod, you will find that the stock is not right to size, it is usually slightly undersize. Metric threads, M4, M5, M6, M8, M10 & M12 are commonly used. M4, for example, means the "standard" M4 thread size: for a bolt, the outside of the thread would be 4mm in diameter, and the spacing between threads (the pitch) would be 0.70mm.

Even so everythng The major diameter of common threads is the same size as available material. Said another way, if you intend to create a ¼" thread, be it 20 or 28 pitch, the material should be.250" maximum, with a couple thou undersized desirable. The same rule applies to any fractional thread size, be it 5/16" or 7/8" diameter. For example, for a class 2a, 1/4-20 external thread, you would turn the work to a diameter between 0.2489 to 0.2408. Then you put a 30 degree chamfer on the end and thread it or screw cut it. Then you check with three wires or a pitch micrometer to be sure your pitch diameter is between 0.2164 and 0.2127" and this should allow that work piece to fit any class 2b nut.
