A datum feature is usually an important functional feature that needs to be controlled during measurement as well. When referring to a screw thread, what does the "20" in 1/4" *20 mean? The rod is 4.44 mm, which appears to be an Imperial no 9. like this: &METRIC_SIZE &THREAD_SERIES-&THREAD_CLASS x&THREAD_DEPTH[.2] &G6 The catch is that you lose the edit value option on the call-out. The callout basically corresponds to the length and diameter of the screws shaft. GD&T Flatness is a common symbol that references how flat a surface is regardless of any other datums or features. The major diameter is the largest diameter of the cutout required for an internal thread, while the minor diameter is the clear opening for an internal thread. . You can modify the hole callout format by editing the hole callout format definition file, calloutformat.txt. . The system the callout uses is very important since similar screws can be different sizes. However, if you find a screw marked with LH, you will know to turn it in the opposite direction!

WebIn GD&T, Perpendicularity can refer to either Surface Perpendicularity or Axis Perpendicularity. True position is a GD&T callout for specifying the position of a feature. Thank you for the reply. Your point matches all of the research I have completed so far, and will bolster my request to the department Best results are obtained by creating holes using the The Square symbol is used to indicate a square feature on a drawing. The counterbore symbol is used on a drawing to indicate that a counterbore hole feature is required. fcsuper: Thanks, I read the entry on your blog and that made it very clear for me.

Due to the specialized gauges required to locate threads from the pitch cylinder, it is good practice for engineers and designers to use the MINOR DIA note for internal threads and the MAJOR DIA note for external threads where possible. Consider a hole defined with a positional tolerance of 1 mm. Its more common if the fastener is special, such as made for use in aircraft. The cylinder portion of the plug can then be located with a CMM or other measuring device. .
