You can find basic information on measuring threads in our article: Threads in practice

Table of pitch diameters for metric threads in accordance with ISO 262

Metric threads, produced in accordance with the ISO standard, are valued for their consistency, versatility and easy selection. The dimensions of metric threads are expressed in millimeters.

The following table contains data that can help identify threads and select the correct components.

Table of metric, pipe and inch threads - comparison

Threads are divided into external (a.k.a. male, screws) and internal (a.k.a. female, nuts). Male threads placed on the outside – shafts, and female threads – inside holes.

The following table provides comparative data for internal and external threads, both metric and inch.

Table of UNC/UNF inch threads

“United National Coarse” and “United National Fine” are the names of American unified standards for threads measured in inches. “UNC” refers to common ratio threads, and “UNF” refers to fine ratio threads.

The following table shows the parameters of inch threads according to UNC and UNF standards.

Table of BSPT tapered pipe threads

“British Standard Taper Pipe Thread” is the name of the standard for British tapered pipe threads with a profile angle of 55°. Although these threads are self-sealing, they can be used with a gasket.

The following table contains data for pipe threads according to the BSPT standard.
