  Pitch

  Pitch is the distance between screw grooves and is commonly used with inch sized products and specified as threads per inch.

  Lead

  Lead is the linear travel the nut makes per one screw revolution and is how ball screws are typically specified.

  The pitch and lead are equal with single start screws.  For multiple start screws the lead is the pitch multiplied by the number of starts
