✅ 8mm diameter screw, 400mm length (15.75 in) for standard builds
✅ Pitch 2mm; lead 2mm per revolution
✅ Copper nut with 4 fixing holes (M3) for secure mounting
✅ Nut height 10.5mm, diameter 22mm; weight 146 g
✅ Stainless steel screw with copper nut provides corrosion and heat resistance

💡 What is a lead screw used for in precision machinery?

Lead screws translate rotary motion into precise linear movement, handy for controlling axis positions in printers and CNC rigs.

• Precise motion control for Z axis in 3D printers, engraving machines, and CNC
• Copper nut reduces wear and extends life of the screw assembly
• Stainless steel body resists corrosion and high temperatures
• Great compatibility with common stepper motor mounts and guides
