Split dies (also known as adjustable die) have adjusting screws allow the die to be compressed or expanded to accommodate slight variations in size, material strength, die sharpness or threading difficulty. Split dies can be used to cut threads in a number of passes, tightening the die on each pass. Split dies are used with a diestock.
Die nuts (hexagon dies) are used for repairing threads or threading a work piece in a difficult to access area. They are not adjustable. A standard wrench or spanner can be used to turn them. Gun nosed dies (solid dies) are not adjustable as can only cut the nominal thread size.
