Key Features
- 4-Start Design for Fast Linear Travel: With 4 starts and a 2mm pitch, each full revolution of the screw translates to 8mm of linear movement - 4x faster than a single-start screw, making it perfect for rapid positioning applications.
- Precision Trapezoidal Thread Profile: The trapezoidal (T8) thread form provides superior load-carrying capacity, smoother engagement, and lower friction compared to standard V-threads, ensuring reliable and accurate motion control.
- 1000mm Full-Length Screw: A generous 1-meter length accommodates large-format CNC builds, tall 3D printers, long-travel linear stages, and custom automation setups without the need for joining or extending.
- Self-Lubricating Copper (Brass) Nut: The included flanged copper nut offers excellent wear resistance, natural lubricity, and low-noise operation. The flange design simplifies mounting to carriages and brackets.
- Low Backlash Operation: The precision-machined thread and closely fitted copper nut minimize backlash, delivering repeatable positioning accuracy critical for CNC and 3D printing applications.
- Corrosion-Resistant Construction: The polished steel screw with anti-corrosion treatment ensures long service life even in humid workshop environments.
- Easy Integration: Standard T8x8 dimensions are compatible with widely available mounting brackets, flexible couplers, pillow block bearings, and anti-backlash nuts for plug-and-play assembly.

Understanding Lead Screw Mechanics
- Pitch vs. Lead: Pitch (2mm) is the distance between adjacent thread crests. Lead (8mm) is the distance traveled per full revolution. With 4 starts: Lead = Pitch x Starts = 2mm x 4 = 8mm.
- Speed Calculation: When driven by a stepper motor at 200 steps/rev (full step), one step moves the nut 0.04mm. With 1/16 microstepping, resolution reaches 0.0025mm per microstep.
- Torque Consideration: Higher lead means less mechanical advantage - a NEMA 17 stepper (0.4-0.5 Nm) is typically sufficient for light-to-moderate loads on this screw configuration.
- Self-Locking Note: 4-start lead screws with 8mm lead are generally NOT self-locking, meaning the load can back-drive the screw. Use a brake or holding torque if vertical positioning is required.
