Two Trees 500mm Trapezoidal 4-Start Lead Screw with Copper Nut

A 4-start lead screw has four independent helical threads, meaning it moves four times the pitch distance per rotation compared to a single-start screw. This design provides faster linear travel per rotation, making it suitable for applications where speed and efficiency are critical, such as 3D printer Z-axes or rapid positioning systems.

The lead screw is manufactured from durable 304 stainless steel, offering excellent corrosion resistance, high strength, and wear properties crucial for consistent linear motion. The accompanying nut is made of copper (brass), chosen for its low friction coefficient and self-lubricating characteristics when paired with steel, ensuring smooth, precise movement and longevity.

Yes, this 500mm trapezoidal lead screw with a 10mm diameter and 2mm pitch is a common size used in many DIY and commercial 3D printers, particularly for the Z-axis. Its precise construction ensures stable vertical movement, which is critical for print quality. Always verify the required length and mounting specifications for your specific printer model before installation.

The 10mm thread diameter provides a robust and sturdy shaft suitable for moderate loads, resisting bending or vibration. The 2mm pitch, combined with its 4-start design, results in an 8mm lead per rotation (4 starts * 2mm pitch), balancing fine resolution with efficient linear speed for precise positioning applications.
