Thanks,
Robert

Measure the bolts, then try any industrial fasteners company. Even eBay is pretty good. I swapped all the bolts on my USE posts with 12.9 high tensile machine screws for about £5.

Zinc-Plated Alloy Steel Socket Head Screw​

10-32 Thread Size, 1-1/2" Long​

If you cannot get them in the UK I would be happy to get some sent over.
I can get 25 pieces for ~$10. Add another $15 for shipping to the UK.

Is it best to use zinc plated steel and not stainless socket head screws right?
Will stainless socket head screws cause corrosion ?

Zinc plated is what was in the post I have on hand. I think that just about anything other than Aluminum bolts would be fine.

Hey Uno-Speedo, were you able to find seat screws in your area?, I ended up buying them at a local hardware store, Ebay also has them. I found some chrome plated steel, 10-32 thread size, 1-1/2" long is the correct size. Ebay has some zinc coated steel. Thanks to Retrobike member Kokies for posting the correct screw size.
Cheers
