2 Start Lead Screw Threaded Rod Lead Screw 8mm Dia Thread 2mm Pitch 2mm without Nut for 3D printer

• T8 lead screw (8mm diameter) is a precision threaded rod used to convert rotary motion into smooth, accurate linear motion—ideal for 3D printer Z-axis, small CNC machines, linear actuators, and positioning systems.
• It features a 2-start trapezoidal thread with 2mm pitch and 4mm lead, delivering stable movement and good mechanical advantage for precise lifting and motion control.
• Made from SS304 stainless steel, the 8mm lead screw offers corrosion resistance, durability, and long service life in DIY and light industrial applications.
• This listing is for the lead screw only (without nut), allowing you to select a matching rectangular or round nut separately as required
