M5 button-head screws of various lengths are used throughout FarmBot to attach plates and 3D printed parts to extrusions, V-wheels to plates, and other components together. They are usually used in combination with M5 washers, and terminated with an M5 tee nut or locknut. The button head provides a wide bearing surface, a low-profile head, and a finished appearance.
