The high-strength screw is a component on the machine tool, and the pitch of the high-strength screw is the distance between two adjacent threads.
Pitch and lead are related but not equivalent concepts. Many people confuse the pitch and lead. The concept of lead is the distance that the screw or nut rotates once and the nut moves on the screw. Lead = pitch * number of heads.
The minimum screw pitch can be achieved: According to the regulations of JB/T9313-1999 special fine thread diameter and pitch series, the minimum pitch is 0.35mm.
