2PCS 400mm（15.75 Inches）Tr8x2 Lead Screw with T8 Brass Nut (Acme Thread, 2mm Pitch, 1 Start, 2mm Lead) for LCD DLP SLA 3D Printer Z Axis and CNC Machine
H**N
Not what I was expecting.
Does not fit an ender 3, the pitch is also not correct to fit in the original lead screw nut.

Never buy this!
It's crap. The ordinary ones from Canadian Tire are better than these.
M**E
Not too accurate made
Screw is fine but nut has too loose contact
K**.
No surprises
Nicely finished. Nut fits with very little backlash
E**O
Great update to increase Z axis stability on FDM printers.
My Ender 3 Pro came with a single T8-8mm lead screw. These are T8 2mm lead screws, which means that you will have more steps to move 1mm up or down and there should be less backlash as well as better torque which translates to the ability to have additional mass on the X axis without detriment to velocity (should not be a LOT o velocity in Z moves anyway).The standard lead screws for an Ender 3 is 365mm, these are a little longer which will allow longer verticals to be installed. My direct drive Ender 3 Pro now has a Z max height of nearly 300mm despite the stepper motor being in the way.
