Bronze Bolts for thru hulls

[ontherocks83]

This winter one of my many projects is to be replacing the original thru hulls with flanged thru hulls highlighted in Mainesail's article

https://marinehowto.com/replacing-th...-and-seacocks/

I have found where to get the flanges and seacocks but can't seem to find a good source for the bronze flush mount machine screws.

Does anyone have a good source or website to get the bronze bolts and hardware.

Thanks all
