A Bunnings assistant suggested I tighten screws of dropping Kaboodle soft close draws. I have removed one draw. The screws just dropped out. How do I replace them when the holes are obviously now too big. Bigger screws? If so what size? Glue? Plugs? Are there custom sized for this Kaboodle problem? The assistant said the screws

need tightening every few years. Is this right? Can it be avoided?
Thanks
