How Do You Screw Mate in SolidWorks?

SolidWorks is a powerful 3D CAD software widely used in various industries to design and simulate mechanical parts and assemblies. One of the essential features of SolidWorks is the ability to create mate relationships between components, allowing for realistic motion and interaction.

The Screw Mate

One of the most frequently used mate types in SolidWorks is the screw mate. This mate allows you to simulate the motion of a screw or a bolt tightening or loosening within a hole or nut.

To apply a screw mate, follow these steps:

  1. Select the two components you want to mate. For example, a bolt and a nut.
  2. Go to the Mates toolbar or right-click on one of the selected components and choose Mate.
  3. In the Mate PropertyManager, select Screw from the list of mate types.
  4. Select an appropriate screw axis by clicking on one of the cylindrical faces or edges of either component. This axis represents the centerline along which the screw will rotate.
  5. Specify additional parameters such as pitch, number of threads, and engagement length based on your design requirements.
  6. Click on Apply to apply the screw mate.

Tips for Using Screw Mates Effectively

The screw mates in SolidWorks offer various options that allow you to customize their behavior. Here are some tips to help you use screw mates effectively:

  • Pitch: The pitch value determines how far the screw advances with each revolution. Higher pitch values result in faster screwing motion, while lower values simulate a slower motion.
  • Number of threads: Adjusting the number of threads can help you achieve the desired level of realism in your assembly.

    More threads will make the screw mate appear more detailed and accurate.

  • Engagement length: This parameter defines how deep the screw enters into the hole or nut. Changing this value allows you to control how tightly the components are mated together.


The screw mate in SolidWorks is a powerful tool that enables you to accurately simulate the motion of screws and bolts within an assembly. By following the steps outlined in this tutorial and utilizing the additional parameters offered by SolidWorks, you can create realistic screw mates that enhance your design and analysis process.

Remember to experiment with different settings and test your assembly to ensure that your screw mates behave as expected. With practice, you’ll become proficient in using screw mates and other mate types to create dynamic and interactive assemblies in SolidWorks.
