..just to add, ad..
I went and ordered x4 nova 1.2 caliper to hub bolts; after you pm'd me back - they fitted ok; as you can see...
Whether it was becasue they were new and/or had new nutlock on already.. or that calibra bolts simply dont fit.. - they looked very similar so to this day unsure, but went with what you kinda suggested and presto.. worked a treat.
