How to Make Screw Holes in Tinkercad

Tinkercad, a popular online 3D modeling and design tool, is used by hobbyists, educators, and designers worldwide. One common task you might need to accomplish with Tinkercad is creating screw holes. While it may seem complex at first, the process is relatively straightforward with the right knowledge and tools. This guide will walk you through all the steps you need to create and modify screw holes in Tinkercad.

Basics of Tinkercad

Before diving into the process of creating screw holes, it’s essential to understand the basics of Tinkercad. It’s a browser-based 3D modeling tool that uses a simple block-building concept, making it easy to create complex designs.

  • Workplane: This is the grid where you create and manipulate your designs.
  • Shapes: Basic building blocks of your 3D models.
  • Hole: A function that can subtract shapes, making it ideal for creating screw holes.

Step-by-Step Guide on Creating Screw Holes

Follow these steps to create a screw hole in Tinkercad:

  1. Start a new design: Click on ‘Create new design’ in the Tinkercad dashboard.
  2. Select a shape: For the purpose of this guide, let’s use a basic ‘Box’ shape. Drag it onto the workplane.
  3. Add a hole: On the right side of the screen, click the ‘Hole’ button and drag it onto the workplane. Resize it to the desired diameter of your screw hole.
  4. Position the hole: Use the arrow tools to move the hole over the box where you want the screw hole.
  5. Group the objects: Select both the box and the hole, then click the ‘Group’ button. The hole will subtract from the box, leaving a screw hole.


Size of the Screw Holes

Sizing screw holes accurately is critical for functional design. A typical rule of thumb is to make the hole 0.1mm larger than the screw’s diameter for a tight fit and 0.2mm larger for a loose fit. This compensates for the slight expansion of material when a screw is inserted.

For example, if you’re using an M3 screw (3mm diameter), the hole size would be:

  • Tight fit: 3.1mm
  • Loose fit: 3.2mm

Here is a table of common screw sizes and corresponding hole sizes:

Screw Size Tight Fit (mm) Loose Fit (mm)
M2 2.1 2.2
M3 3.1 3.2
M4 4.1 4.2
M5 5.1 5.2
M6 6.1 6.2

Enhancing Screw Holes with Threads

To create more realistic and functional screw holes, you can add threads. To do this, you can use the ‘Thread’ shape in Tinkercad’s ‘Shape Generators’ library. Here’s how:

  1. Click on ‘Shape Generators’ on the right side of the screen.
  2. Click on ‘All’.
  3. Search for ‘Thread’ and drag it onto your workplane.
  4. Size and position the thread shape inside your screw hole.
  5. Group the shapes together.

Note: Keep in mind that Tinkercad is a simplistic 3D modeling software, and the threads created won’t be as precise or as high-quality as those made in more professional-grade software like Fusion 360.

  • Through Holes: These holes go completely through the object and are typically used when you want the screw to extend beyond the surface.
  • Blind Holes: Blind holes do not go all the way through the object. They are used when you want the screw to be flush with the surface.
  • Counterbore Holes: Counterbore holes have a larger diameter at the top, allowing the screw head to sit below the surface. These are useful when you want a flush finish.

To create different types of screw holes, you can adjust the shape and size of the hole object in Tinkercad accordingly.

3. Can I add multiple screw holes to one object in Tinkercad?

Yes, you can add multiple screw holes to a single object in Tinkercad. Here’s how:

  1. Place the first screw hole on the object using the steps mentioned earlier.
  2. Create additional screw holes by duplicating the existing hole or by adding new holes following the same process.
  3. Position the new holes as desired on the object.
  4. You can adjust the size, spacing, and orientation of each hole individually to meet your requirements.
  5. Remember to group the object and holes together to ensure they function as intended.

4. How can I align screw holes with precision in Tinkercad?

Aligning screw holes precisely in Tinkercad can be achieved using the grid and snapping features. Here’s what you can do:

  1. Enable the grid by clicking on the grid icon at the bottom of the workplane.
  2. Adjust the grid spacing to your desired level of precision using the options in the toolbar.
  3. Position the first screw hole using the grid lines as reference.
  4. To align subsequent screw holes, you can use the snapping feature. Select the hole you want to align and move it close to the existing hole. It will automatically snap into place when it’s aligned.

By using the grid and snapping features together, you can ensure precise alignment of screw holes in your Tinkercad designs.
