what's the blue finish on this locknut actually for, or is it just cosmetic?

Purely functional. The blue anodization is an aluminum surface treatment that adds corrosion resistance, so it holds up better in environments where moisture or fluid exposure is a concern. The aluminum base keeps weight down, and the anodized coating helps protect against degradation over time. It is not just a color choice.

got a -16 AN setup, is this the right locknut size or am i mixin stuff up

For AN 924 locknuts, the “-16” is the dash size, and this part is a -16. So if your hardware calls for a -16 AN 924 locknut, this matches that size.
