Threaded Bolt and Nut

Bolt Modeling > 3D Bolt > Threaded Bolt and Nut

This tool is used to create two types threaded portion of bolt and nut.
  1. Axi-symmetric thread
  2. Helical thread

Axi-symmetric thread

This will create axi-symmetric threaded portion of bolt and nut in specific mesh pattern based on the given bolt and nut parameters. First user needs to create the half symmetry thread section using the create thread section option. Then the created section faces can be given as inputs for bolt and nut faces to create threaded bolt and nut.

Create Thread Section

This option will create the half pitch symmetry mesh for bolt and nut.

Example: Axi-Symmetric Thread Section

Example: Axi-Symmetric Thread Solid

Note:
  1. Number of elements in bolt and nut root should be multiples of 3 and should be 6 and above.
  2. Once the section faces are created, do not change the parameters in the dialog when those section faces are used for solid bolt and nut creation.

Helical thread

This will create helical threaded portion of bolt and nut based on the given bolt and nut parameters.

Example: Helical Thread

Note:

Circumference element count must be divisible by axial element count per pitch to have good quality hex elements in the helical thread protion of bolt and nut.
