Basics of Design Steel structure 
Nominal diameter = The diameter of the shank of a rivet before riveting ,is called the nominal diameter .For a bolt ,the diameter of the unthreaded portion of the shank is called its nominal diameter .

Effective diameter or gross diameter : The effective or gross diameter of a rivet is equal to the diameter of the hole it fills after riveting . For a bolt ,the nominal diameter is same as the gross diameter .

Net area : The net area of a bolt  is the area at the root of thread .
