Disclosure: The table knives at my house are all slightly bent. They are great for opening paint cans, reattaching outlet covers, and in this case removing drive fasteners from drawers when there has been an "oops" moment during assembly. To avoid this, we recommend owning multiple flat head screwdrivers and knowing where they are when needed.
Building drawers is one of the most time consuming aspects of furniture assembly, particularly on six and seven drawer units. While the exact components of a drawer may vary slightly from model to model, many use two plastic pieces at the corners, drawer brackets and drive fasteners.
Plastic hardware can be surprisingly resilient, which is wonderful for keeping drawers together. Each fastener has four sets of teeth for gripping the sides of each predrilled hole:
These hardware components connect to the drawer sides, which are symmetrical, if not in every case identical. The size of the predrilled holes for both drawer brackets and drive fasteners are the same, and that may cause some confusion. The assembly instructions provide very good depictions of how each piece connects but if a mistake is made it should be fixable.
To separate unwanted connections, shimmy a thin object between the panels.
If any damage occurs during this process, or further assistance is needed, please contact customer service.
