2017 05 26 nbsp 0183 32 Pitch is the distance from the crest of one thread to the next Because the vast majority of screw threadforms are single start threadforms their lead and pitch are the same Single start means that there is only one ridge wrapped around the cylinder of the screw s body Each time that the screw s body rotates one turn 360 176 it has advanced axially by the width of
Pitch is the distance between screw threads 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
