Seat post bolts - M4 x 30 capscrew jumbo head
Struggling massively to find a replacement seat post bolt for one I had to drill out on a 1992 Basso Laguna. It's an M4 x 30 socket head cap screw with oversized head, and coarse threads. Any idea where to buy real niche stuff like that online? Local fastener shops here don't have anything remotely similar... May have to settle for Philips head. Cheers!
