What is Lightning, exactly?

Lightning is an add-in for SOLIDWORKS. It uses your existing fastener library and makes it searchable. You select the file you want and drag it into your assembly.
  • Extract data from your existing files

    We help you extract sizes and materials from your existing fastener library, store this info in our database and make it searchable. You need to do this only once.

  • Drag the part into your assembly

    Once your selection is complete, use one of the buttons to drag the part file directly into your assembly. If the part has mate references, it snaps in place.

  • Find your fastener in a few clicks

    Lightning has a user-friendly filter that lets you select a fastener type, size, material and coating. If you pre-select a hole, we select the right bolt diameter.

  • Lightning adds a washer

    After you add the file, we do our magic. Lightning can add a washer under your bolts and nuts. You can even select your preferred washer. It

  • Works best with mate references

    If your parts have mate references, SOLIDWORKS automatically adds mates when you drag a part into your assembly. We use these mates to add washers + patterns.

  • Lightning adds a pattern

Lightning is currently in beta

We built the first version of Lightning from home during the first lockdown. Now we are looking for users and for feedback, so we can improve the product quickly. 

To accelerate that process, we made Lightning freely available. Just download it, request a free beta license from within the product and start using it. Your license is valid for at least 6 months.

If you have any feedback, please let us know! We built a feedback form right into the product. Or email us at [email protected].

Is your fastener library a mess?

We can help with that. We spent 500 hours building the best fastener library available, with a focus on consistency and stable mates. The data is straight from the ISO standards. The files are small, robust, fast and PDM compatible.

Frequently asked questions

How does Lightning integrate with SOLIDWORKS?

Lightning is an add-in for SOLIDWORKS 2017 and newer. Its toolbar is visible for assemblies. You can always access your settings through the Tools menu.

Is Lightning compatible with Toolbox parts?

Lightning should be compatible with all SOLIDWORKS parts. We are not a fan of the Toolbox though, so we built our own fastener library.

How much time does it take to get started?

It takes some time to extract data from your fasteners and put it into our database.

Depending on how consistent your filenames and configuration names are, it usually takes 10 minutes to 1 hour to set up properly. We can also do this for you.

You only need to enter this data once and you can share the resulting database with your colleagues.

Do I get updates?


Lightning checks for updates every few days and notifies you when it finds one. You can then decide when you want to install the update.
