Web cosmetic threads describe the attributes of a specific hole so you need not add real threads to the model. You use the smart dimension tool to add the callout in a side view or section view of the external thread. For a threaded hole with a counterbore where does the depth of the thread start. When a thread is called out on a drawing, the information will include the nominal size (diameter) and may include either the threads per inch or thread pitch, depending on whether inch or metric threads are being used. Inch thread and metric thread callout on the engineering drawing.
Hello nx community, i would like to display the thread of a hole feature in the drawing. Annotation standardization is provided by the asme y14 series of standards. Another option is to create a section view through the hole, right click on. Is it from the top surface or from the bottom surface of the counterbore.
In nx 7.5 i am trying to dimension a helical coil thread. Threads per inch & thread pitch. Web cosmetic threads describe the attributes of a specific hole so you need not add real threads to the model.

You use the smart dimension tool to add the callout in a side view or section view of the external thread. Is it from the top surface or from the bottom surface of the counterbore. Web min full thread is sloppy and unnecessary because the thread depth callout fully defines acceptable limits for the threads. Web some examples include thread specifications, surface finishes, surface quality, and dimension tolerances. Web in drawings, you can add cosmetic thread callouts to external cosmetic threads.

The First Time You See A Callout Can Be A Little Confusing, But It’s Pretty Straightforward Once You Know What The Numbers Are Meant To Stand For.

Here Are A Few Important Things To Remember When Specifying Threads:
(see also the image below) The tap has a tapper on it, s if i don't tell where to the machinist to stop in depth with the tap, the hole will be over sized, so the ntp fitting will not thread in tight. It is the most popular thread used for traversing linear motion (for example, leadscrews and power screws) due to its ability to withstand large loads and ease of manufacturing. Web 10 nov 06 10:01.
Web Min Full Thread Is Sloppy And Unnecessary Because The Thread Depth Callout Fully Defines Acceptable Limits For The Threads.
The callout basically corresponds to the length and diameter of the screw’s shaft. Web use the hole/thread callout tool in a drawing to add a callout to an external thread feature. Web helical coil thread callouts on a drawing. Specify threads on a 2d drawing with a thread specification callout (aka thread hole callout) for metric sizes, specify size with the thread pitch (diameter x pitch in mm);
Hello Nx Community, I Would Like To Display The Thread Of A Hole Feature In The Drawing.
A cosmetic thread represents the minor (inner) diameter of a thread on a boss or the major (outer) diameter of a thread on. Web cosmetic threads describe the attributes of a specific hole so you need not add real threads to the model. This handout will focus on the standards of annotation for fasteners, and hole callouts (local notes). A thread note must be included on all threaded parts, with a leader line to the external thread or to an internal thread in the circular view.
A cosmetic thread represents the minor (inner) diameter of a thread on a boss or the major (outer) diameter of a thread on. The callout basically corresponds to the length and diameter of the screw’s shaft. This is an overview on how to define screw threads on engineering drawings, according to the unified inch screw thread standard. Web in this comprehensive article, we will explore the various methods used for manufacturing threaded holes, along with the standard practices for calling them out in technical drawings and specifications. A thread note must be included on all threaded parts, with a leader line to the external thread or to an internal thread in the circular view.
