WebApr 26, 2016 · National Pipe Thread series have the same 60° included angle as Sellers thread. On the other hand, for sealing capability, tapered (pressure-tight) threads have crest and root shapes that differ from Sellers. For example, the NPT has a crest width of 0.038 to 0.062 pitch, which is sharper than the 0.125 pitch of Sellers.

WebThese are used for checking the pitch of a screw thread. They are available with 55° and 60° included thread angles. They are also available in metric and inch pitches. A 60° included thread angle screw pitch gauge is shown in Fig. 1.48: WebBSP threads have a 55° included angle and have rounded peaks and valleys (this is a Whitworth thread form). Here are the actual thread dimension data for BSP threads. The major diameter is a bit smaller than the actual OD of the pipe, and the minor diameter should be very close to what you would measure inside the female threaded end of a fitting.
