Understanding Fasteners in SolidWorks

Fasteners refer to bolts, nuts, screws, washers, and other mechanical parts that are used to join different parts of an assembly together. SolidWorks offers users a comprehensive library of fasteners that can be used in designs. This library includes a variety of fasteners manufactured by different companies, and users can add custom fasteners to the library to expand it.

Basic Fastener Insertion

To insert a fastener in SolidWorks, the first step is to identify the bolt or screw required for the design. The design engineer should select a fastener that is appropriate for the application and meets the strength and size requirements of the assembly. Once you have the fastener specs in mind, follow these basic steps to insert it into your design:

1. Open the SolidWorks design and select the “fasteners” option in the toolbar

2. Select the type of fastener you would like to insert

3. Specify the fastener size and thread pitch

4. Click on the location in the assembly where the fastener will be inserted

5. SolidWorks will automatically insert the fastener into the assembly

Advanced Techniques for Inserting Fasteners

There are several advanced techniques for inserting fasteners in SolidWorks. These techniques are very useful when working with assemblies that have complex geometries or have multiple fasteners that need to be inserted at once. Here are some of the advanced techniques for inserting fasteners:

1. Using the “hole wizard” feature

The hole wizard feature in SolidWorks allows users to add holes for fasteners directly into the model. The hole wizard feature also enables users to specify the size and location of the hole, as well as the type of fastener that will be inserted.

2. Create a custom library for fasteners

Creating a custom library for fasteners will save you time and make it easier to insert fasteners into your designs. Users can create a library of commonly used fasteners in SolidWorks, which can be accessed easily during a design. Custom libraries can include fasteners not found in the SolidWorks library and user-defined fastener specifications.

3. Smart Fastener tool

The Smart Fastener tool in SolidWorks is a handy feature that automatically detects the holes in the assembly and applies the correct fastener type and size. The tool can also automatically place washers and nuts in the correct location.

Best Practices for Managing Fasteners in SolidWorks

To manage fasteners in SolidWorks effectively, here are some best practices that can be adopted:

1. Standardize fastener selection across designs

Using the same fasteners across all designs will simplify the selection process and reduce the chances of selecting the wrong size for the application.

2. Create a fastener checklist

Having a fastener checklist will help design engineers remember which fasteners they need to use in each assembly, reducing the chances of forgetting a fastener.

3. Label Fasteners

Adding names or notes to fasteners that can be seen in the SolidWorks model makes it easier for other team members or technicians to understand which fasteners are required and where they need to be inserted.

Troubleshooting Fastener Insertion

When inserting fasteners into a SolidWorks assembly, there are some common problems that users experience. Here are some of the issues you may encounter and how to resolve them:

1. Threaded Fasteners Appear Damaged

If the threaded fastener does not appear correctly in the model, a possible solution is to increase the display quality. To do this, go to “options” in the SolidWorks menu, and select “document properties.” From there, go to the “image quality” tab and increase the slider value.

2. Fastener Threads Do Not Align

If the fastener threads do not appear to align correctly, there may be a problem with the model geometry. One solution is to adjust the model, i.e., modifying the holes or slots that the fasteners are going into.


Inserting fasteners into SolidWorks models is a vital part of the design process. By following the basic and advanced techniques and adopting best practices, design engineers can save time and avoid common problems. With a little patience, design engineers can create an optimized and well-constructed assembly that is robust and efficient.#
