WebbMeasure screw diameter, or screw size, by measuring the width of the threaded part of the screw. This corresponds to the first number of the thread size. For inches, any diameter smaller than 1/4" is indicated by a number, referenced in the table below (e.g. 8 corresponds to 0.164"). For metric screws, this is the number of millimeters preceded ... WebbChange Gears for Threading. The series of gears that drive the lead screw are called change gears because you change them to turn different thread pitches. Changing these gears varies the speed that the lead screw turns in relation to the speed that the spindle turns. This allows you to cut threads with different numbers of threads per inch.
