In SolidWorks, a bottoming tapped hole is a specific type of threaded hole that is used when you need to create a blind hole with threads that extend all the way to the bottom of the hole. This can be useful in various scenarios, such as when you want to attach a screw or bolt securely into a part.
Creating a Bottoming Tapped Hole
To create a bottoming tapped hole in SolidWorks, follow these steps:
- Create a Sketch: Start by creating a sketch on the face or plane where you want the tapped hole to be located. You can use various sketching tools to define the shape and size of the hole.
- Select Hole Wizard: Once your sketch is ready, go to the “Features” tab and select “Hole Wizard”. This tool allows you to create different types of holes, including tapped holes.
- Choose Tapped Hole Type: In the Hole Wizard dialog box, select “Tapped Hole” as your desired type. This will give you access to additional options specifically for creating threaded holes.
- Select Bottoming Tap Drill Size: In the Tapped Hole dialog box, choose the appropriate size for your bottoming tap drill from the available options.
The drill size should match the size of the tap you plan to use for threading.
- Define Depth: Specify the desired depth for your bottoming tapped hole. This determines how deep the threads will be in relation to the surface of your part.
- Add Thread Specifications: You can also add additional thread specifications if needed, such as thread class and fit type. These details ensure proper compatibility with the corresponding screw or bolt.
- Finish and Confirm: Once you have defined all the necessary parameters, click “OK” to create the bottoming tapped hole. SolidWorks will generate the threaded hole based on your specifications.
Benefits of Bottoming Tapped Holes
Bottoming tapped holes offer several advantages over other types of holes or fastening methods:
- Secure Fastening: The threads in a bottoming tapped hole extend all the way to the bottom, providing a more secure fastening solution compared to regular through holes or blind holes without threads.
- Efficient Use of Material: By using a bottoming tapped hole, you can save material and reduce overall weight by eliminating the need for additional nuts or washers. The threaded hole itself acts as a built-in fastening element.
- Clean Aesthetic: Bottoming tapped holes create a clean and professional appearance, especially when used in visible areas of your design.
They eliminate the need for protruding fasteners that may detract from the overall look.
- Ease of Assembly: When using bottoming tapped holes, assembly becomes easier as you can directly thread screws or bolts into the hole without requiring additional hardware. This saves time and simplifies the overall manufacturing process.
Conclusion
In summary, a bottoming tapped hole in SolidWorks is a threaded blind hole that extends all the way to its bottom. It provides secure fastening, efficient material usage, a clean aesthetic, and ease of assembly. By following the steps outlined above, you can easily create bottoming tapped holes in your SolidWorks designs, enhancing both functionality and visual appeal.
