I've found the part number but it's not helped me narrow down any non OEM replacements unfortunately and for a set of OEM ones I'm looking at the best part of £10 which I'm not prepared to pay for a couple of Suzuki cheese grade screws
The ones on my pointy seem strange in that from a quick look they do look like screws rather than any sort of metric bolt which has confused me a little bit, the ones for the curvy look like they could be straight replaced with some nice stainless metric bolts but I don't
think that's going to be the case for me
