I am not sure price of hub bolts you have looked at maybe high if they are stainless but Neal Videan has them cad plated at $6.60 each Australian
Nyloc nuts are just fine, as I mentioned. You just have to understand their limitations. They do not remain tight, so they need maintenance over the years. They are not fireproof, as Greg points out, so they should not be used where they are exposed to heat. They are generally prohibited in front of the firewall, or where flames can reach.
As Vic points out, chemicals will usually not let go of the clamping load, which is a big plus. The downside of chemicals is that sometimes the situation does not allow proper cleaning or curing times. Application in the shop is usually ideal.
Lock wire is often not effective as the wire will stretch, allowing the clamping force to release. Like a Nyloc, you won't lose the nut, but if you need the clamping force to remain stable, use chemicals even if lock wiring is required.
