If I'm looking to buy some 316 stainless bolts, I'd like to see links to the applicable nuts for that size/material/threads/etc. For certain sizes, the nut selection can be limited and might not meet my needs. Then, I have to start over with 304 or something else. In my most recent case, I had to order some of the components from a different store.
My gripe is they do ranges very poorly so you wind up spending a lot of time specifying an exhaustive set of possible sizes that may work in order to see all the various options of things that have some critical feature or dimension you need.
