2pcs 500mm Tr8X2 Lead Screw with T8 Brass Nut for 3D Printer Machine Z Axis(Acme Thread, 2mm Pitch, 1 Start, 2mm Lead)

I am building a Lowrider V3 CNC from V1 Engineering and these form part of that build. I have done the 3D printing part of the build and gathering all of the necessary parts. Whilst I haven't put everything together yet, after my initial research and inspection of these, I am very happy. I will update the review once I have completed the build.

the box was on the big side but the t8 lead screws are nice and straight, thanks good seller ;)_

Looks good but I haven't installed it yet.

Me sirvió mucho para actualizar mi Ender 3 Max con la aplicación de el doble motor para el eje Z. Excelente compra los componentes son de buena calidad y llegaron antes de lo esperado.

Good quality for replacement on my Ender 5 printer.

Tiene un acabado en las orillas no tan bueno, de ahí en más todo excelente

perfect replacement for Monoprice brand 3d printers, I have a Monoprice MP10 and the Z-axis lead screw was giving me issues so I decided to order this replacement after getting the specifications wrong like 5 times. Tr8x4, 500mm long, 2 starts, and 4mm lead was the perfect mix of specs for my needed replacement. You will need an additional 8mm to 5mm coupler to affix the motor to the leadscrew, as the factory supplied coupler is only 5mm to 5mm. I included a picture of my old “400mm” z-axis lead screw next to one of these brand new 500mm ones.
