bolt sizes help please?

[Preston-m3]

Hi All, Can anyone tell me the sizes and lengths of bolts needed for the items below. Mine are manky and I would like to replace them.

USE seat clamp bolts
Water bottle holder bolts
DCD bolts

Thanks.

I don't mean to sound rude, and I could measure mine, but you could also measure your own. I'll assume you're not sure how to measure them, so hope this helps;

Re:

Hi, I don't have any bottle cage bolts to measure and there are that many different head types etc on these bolts and i don't want to order the wrong ones that's why I asked the question. Thanks for the guide, will have a look.

Ah, no problemo.

Bottle cage bolts are M5. 25mm long should be plenty. Choose the head type you like best, it really doesn't matter for bottle cages.

12mm is plenty for a bottle cage, maybe if you cages have a thick mounting flange you would go to 15mm.

I think the use posts are M5 by 45mm or maybe 50mm - mine are off the bike at the moment so I can check easily - give us a prod if I forget ...
