Questions

Why is there no hot-dip galvanized option below M8?

The zinc layer is too thick for smaller threads, so hot-dip galvanizing starts at M8.

Partial thread or full thread?

Partial thread keeps a smooth shank across the joint, which is stronger against side load and lines the parts up more accurately. Full thread suits tapped holes and short joints where the nut runs up to the head.
