After a couple of years the cheap screws that came with it were rusty and most were snapping in half so I've had to gradually replace all 270 (ish) of them. I wasn't sure how many I would need but have ended up buying 4 packs and it wasn't quite enough so I've had to buy 2 more packs to finish the job.
