| Internal Thread Dimensions for Class 5 Interference-Fit Threads |
| Internal Thread Dimensions for Class 5 Interference-Fit Threads ANSI/ASME B1.12-1987 (R1998). The following thread detail specifications are typical for studs applications.
Data within design chart is based on internal threaded members being steel ASTM A-325 (SAE Grade 5) or better. Le = length of engagement. |
|
| Minimum Threads Protruding Beyond Nut |
| A minimum thread protrusion length is given to ensure that all the threads are engaged. This is required to ensure a full-strength fastener. Equipment component drawings should specify the type, length, and size of bolt, stud, bolt-stud, etc. to be used to obtain the proper thread protrusion. |
