3501 Series Lead Screw (8mm Lead, 4 Start)

The pitch of a lead screw refers to the distance from one thread to the next. The 8mm lead screws have 4 threads with a 2mm pitch which yields 8mm of linear travel of a lead screw nut for each rotation of the lead screw. The 8mm diameter makes them compatible with many components such as 8mm pillow blocks and 8mm thrust bearings.
