TIL that the tiny headless screws that hold the curtain rod in the curtain rod bracket are called grub screws and they can have a cone head (pointy) or a cup head (rounded).I need one (1) but I have to buy a pack of either 40 or, wildly, 240 assorted ones. If you ever need the odd one hit me up and I'll post, I reckon I'll have a couple of spares.
