"If the chip board is poorly made it will break apart when you tighten the CAM nut causing it not to sit straight and this will cause the CAM nut to twist and it will break apart. You may not be able to get the part of the Cam nut that is between the clip board and the CAM bolt. I found this is a poorly made fastner to use on items that needs a strong fastner to assembly an item that will support a lot of weight."
