Using the hole function to create a hole

To create a screw nail in Fusion 360, you can use the hole function to first create a hole and then add threads to it. This can be done by opening the thread command under the Create option in the toolbar.

When creating the hole, you can uncheck the full-length command to customise the location of your threads. This will allow you to edit the length and offset of the threads. Fusion 360 will automatically fill in a Thread Type that fits your model and unit of measurement. However, you can change this by clicking on the drop-down menu and selecting from a large assortment of alternative options.

The number automatically filled into the size function is the closest manufacturable thread size. If you would like to change to a different size, simply select your preferred manufacturable thread size, and the model will automatically update to configure to your choice.

To add threads to a pre-existing hole, follow the same procedures as you would when creating External Threads, but this time, select an interior face. Once you are finished creating threads, you can implement your components into a broader assembly to create a more complex and comprehensive design.

Using the thread function to add threads to an existing hole

To use the thread function to add threads to an existing hole in Fusion 360, you need to follow a similar procedure as when creating external threads, with a few key differences. Firstly, open the thread command under the "Create" option in the toolbar. When creating threads for a pre-existing hole, you will need to select an interior face instead of an exterior one.

Before you begin creating the threads, you can customize certain aspects. To do this, uncheck the "full-length" command. This will allow you to edit the length and offset of your threads. You can also change the thread type by clicking on the drop-down menu and selecting from a range of options. If you want to adjust the size, simply change the number in the size function to the desired manufacturable thread size, and the model will automatically update to match your choice.

Once you have customized the thread specifications to your requirements, you can begin creating the threads. After you have finished, you can implement your components into a broader assembly to create a more complex and comprehensive design. This process will enable you to add threads to an existing hole, providing you with the flexibility to design and modify threaded objects in Fusion 360.

Customising the screw's pitch, thread angle, and minor diameter

When creating a screw nail in Fusion 360, you can customise various aspects, including the pitch, thread angle, and minor diameter. These parameters can be adjusted to meet specific requirements or create unique screw designs. Let's delve into each of these customisation options:

Customising the Screw Pitch:

The pitch of a screw refers to the distance between the threads and plays a crucial role in determining the speed and efficiency of the screw's advancement. In Fusion 360, you can customise the pitch by adjusting the distance between the individual threads. By increasing or decreasing this distance, you can create a coarse or fine pitch, respectively. A coarse pitch allows for quicker insertion, while a fine pitch provides more thread engagement and is often used for precision applications.

Modifying the Thread Angle:

The thread angle of a screw affects its holding strength and ease of assembly. By customising the thread angle in Fusion 360, you can create different thread profiles. While a 60-degree thread angle is a common standard, providing a balance between strength and machinability, you can experiment with different angles to meet specific requirements. For instance, a sharper thread angle might offer better holding power, whereas a shallower angle could be used when ease of assembly is a priority.

Adjusting the Minor Diameter:

The minor diameter of a screw, which refers to the smallest diameter of the thread, is critical in determining the engagement between the screw and its mating thread. By customising the minor diameter in Fusion 360, you can control the amount of material between the root of the thread and the core of the screw. This allows you to optimise the screw for specific applications—increasing the minor diameter for added strength or decreasing it to reduce weight and material usage.

It's important to consider the specific application and requirements of your screw nail design when customising these parameters. Balancing factors such as strength, ease of assembly, and weight will help guide your decisions when adjusting the pitch, thread angle, and minor diameter in Fusion 360.

Additionally, Fusion 360 might offer built-in options to download screws of specific dimensions. However, customising these parameters allows for unique screw designs tailored to your needs. You can also refer to online resources, such as YouTube videos and forums, for guidance on using the Fusion 360 API to achieve your desired customisations.

Creating a screw using the Custom Screw Creator

To create a screw using the Custom Screw Creator in Fusion 360, you can follow these steps:

  • Exit Fusion 360.
  • Install the downloaded .msi file by double-clicking on it.
  • Reopen Fusion 360.
  • Type the letter "S" to bring up the shortcut menu, then type "create screw".
  • Use the Custom Screw Creator to define the screw's parameters, such as height, width, and head size.

However, it is important to note that some users have reported limitations with the Custom Screw Creator. For example, you cannot currently specify the thread pitch or other specific thread parameters beyond the diameter of the threads. Additionally, the cut operation for the screw head may cut all bodies, not just the screw, affecting other components.

For more complex screw designs, you may need to explore other methods, such as creating a rough shape and using the threading tool in Fusion 360, or downloading screws from external catalogs like McMaster, which is integrated into Fusion 360.

Using the threading tool to make a rough shape

To create a screw nail in Fusion 360, you can use the Thread command under the Create option in the toolbar. This will allow you to create threads and customize their location, length, and offset.

  • Start by creating a cylinder with a diameter of 20 mm and a height of 30 mm at the 0,0 origin point. You can do this by going to CREATE > Cylinder.
  • Hide the default light bulb of Body1 by left-mouse-clicking (LMC) on it.
  • Create a polygon inside the cylinder by going to SKETCH > Polygon > Inscribed Polygon. Select the bottom plane as the face and set the 0,0 point as the center. Set the radius to 20 mm and LMC to save the settings. Stop the sketch.
  • Use CREATE > Extrude to create a thicker base for your screw nail. For example, you can extrude by 5 mm to create a thicker head.
  • Show the light bulb for Body1 by right-mouse-clicking (RMC) on it.
  • Move Body1 upwards by a certain distance (e.g., 5.0 mm) in the Y-direction to create space for the screw thread. You can do this by RMC on Body1 and selecting Move.
  • Now, you will use the threading tool to create the threads. Go to CREATE > Thread.
  • Click on the "Modeled" option and then select the cylinder's round vertical face. Click OK.
  • You can now customize your thread settings. Fusion 360 automatically fills in a Thread Type based on your model and units. You can change this by clicking on the drop-down menu and selecting from various options.
  • Specify the size of your threads. Fusion will automatically fill in the closest manufacturable thread size, but you can change this if needed, and the model will update accordingly.
  • (Optional) Further customize your shape settings. Specify the hole type (Simple, Counterbore, or Countersink), hole tap type (Simple, Clearance, Tapered, or Taper Tapped), thread offset (distance covered by the thread), and drill point (flat or angled).

By following these steps, you can use the threading tool in Fusion 360 to create a rough shape for your screw nail, customizing various parameters along the way.
