Shhh - don't tell anyone! This bolt has a hidden compartment for hiding your super-secret spy plans; the bolt head un-screws to reveal a hollow bolt.
This was just a fun project to try out some ideas, and give me an excuse to work on my 3D CAD skills. It turned out to be a bit trickier than I expected to get all the part to fit the way I wanted, but it was a good learning experience.
The OnShape 3D CAD files for this are available here:
