There are all sorts of screw diameters - major, minor, pitch, mean, etc., but in general a screw diameter is a called by its nominal diameter which is the major diameter of the screw, approximately. For example a 1/2 inch screw has a nominal diameter of 1/2 inch.
NB (nominal bore) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters. NB (nominal bore) is also frequently used interchangeably with NPS.You can refer more details herehttp://www.piping-engineering.com/nominal-pipe-size-nps-nominal-bore-nb-outside-diameter-od.html
bore of the pipe is the internal diameter of pipe but the nominal diameter of pipe is the dia of a circle which is draw through a point which is situates at exactly half of the thickness of pipe or we can say that (outer dia of pipe- thickness of pipe )=nominal bore of pipe.
Diameter drill is drilling.
nominal diameter
The diameter of a pipe is its width across an open end of the pipe. The inside diameter is the width measuring on the inside of the pipe; the outside diameter is the width measuring on the outside.______________________________________________________________________________________________________For a pipe of circular cross section, its nominal diameter is the diameter of the cross section.The inner diameter is the measuring on the inside of the pipeThe outside diameter is the measuring on the outside of the pipe.
The inside diameter (ID) is 8 inches. The nominal pipe size (NPS) and outside diameter (OD) depend on the thickness of the walls of the pipe.
diameter 16
Pipe with a Nominal Bore of 4 inch (100mm) Outside Diameter 114.3mm
The nominal pipe size is closest to the inside diameter; however, for exact calculations both should be looked up in a table based on the scheduled pipe size.
The nominal diameter of a strand refers to the diameter of the individual wires used to make up the strand. It is typically measured in inches or millimeters and is a key factor in determining the strength and flexibility of the strand. It is important to consider the nominal diameter when selecting a strand for a specific application.

NB = Nominal Bore
it is the clear cover for stirrups. effective cover of the reinforcement = nominal cover+ diameter of stirrups+half diameter of main bars
bore of the pipe is the internal diameter of pipe but the nominal diameter of pipe is the dia of a circle which is draw through a point which is situates at exactly half of the thickness of pipe or we can say that (outer dia of pipe- thickness of pipe )=nominal bore of pipe.
