These product lines differ primarily in their lead to diameter ratios. A screw’s lead is the distance the nut travels in one revolution of the screw. A screw’s lead angle is a measure of the lead/diameter ratio (see the formulas in the Application Engineering section). ACMEs have the lowest leads for a given diameter with lead angles ranging from about 2 degrees to 5 degrees. HILEADs have intermediate lead angles ranging from 4 degrees to about 16 degrees, TORQSPLINE LEAD SCREWS have very large lead/diameter ratio with lead angles of 17 degrees to 40 degrees.
