Single Metal Dowel Pin M10 x 50mm (PL4 Greenbank)

Hello I'm in need of a single metal dowel pin in M10 x 50mm size.

I've been to all the shops I know of that might sell such a thing but none of them have them and since I only need a single one was hoping someone might have one spare they no longer needed.

I'm in the PL4 area and can travel a certain distance to collect if needed.

Thanks.
