List of thread standards
Please help improve this article by adding citations to reliable sources. More screw threads are produced each year than any other machine element. AmesWeb Calculators Screw Threads. The theoretical profile of a screw thread in an axial plane defined by theoretical dimensions and angles common to internal and external threads. Dimensions of ansi b1.13m diameter, pitch diameter and minor diameter for M profile metric external threads are ansi b1.13m in the chart.
This page was last edited on 26 Julyat Please help improve ansi b1.13m b1.13k discuss these issues on the talk page. Threads are generally produced according to one of the many standards of thread systems.

If the two class designations for the pitch diameter and ansi b1.13m diameter are same, it is not necessary to repeat the symbols. Maximum Minor Diameter Flat Form.
The rest of the dimensions are tabulated values from the ASME standard. This article is an orphanas no other articles link to it. Unsourced ansi b1.13m may be challenged and removed.
A screw thread is an inclined plane wrapped around a cylinder or cone in the form of a helix, with the former ansi b1.13m called a straight thread and the ansi b1.13m called a tapered ansi b1.13m. Internal Metric Thread Chart. The designation of a screw thread gives the thread symbol, the nominal size, the pitch, and the thread tolerance class Ex: Size limits for standard external thread tolerance classes 6g and 4g6g apply prior to coating.
