Part 14 is the short carriage bolt used for assembling the front frame.
The metal washer and cap nut needed comes pre-mounted on the short carriage bolt. This is an 8-pack.
How to assemble?
Use the short carriage bolt when you assemble the front frame. To ease the process, you can use a rubber mallet before tightening the nut using the Q/R tool. View the video manual or check chapter 2 in the assembly manual.
