    T8 8mm 4 start Acme lead screw 1040mm long

    Posted by Bruce Levison on Jul 3rd 2018

    Item came within a week and well packaged. Unlike my experience other vendors, this lead screw was not dmamged (bent) during shipment, and well worth the money for a nice straight length of T8 8mm 4 start Acme lead screw that is 1040mm long. Fits the standard nut that was already on my Ender 2 3D printer. I was able to extend the 3D printers Z axis to about 1 meter length using this lead screw.

    VERY well packaged

    Posted by Norman on Jun 13th 2018

    The lead screw came contained inside bubble wrap around which was a sort of supportive square made out of two piece of cardboard, then that was wrapped in more bubble wrap bigger packages of air. Finally, they wrapped it in shrink wrap, making a sort of straight lead screw burrito, and put all of that in a large box. Highly reccommend

    Good, solid lead screws for 3d printer/light cnc

    Posted by Justin on Jun 7th 2018

    They're good solid lead screws, what can I say. I've used 8 in two different 3d printers and they're very accurate, very repeatable, and they're easy enough to cut to length. I'm not sure how they fair for heavier work but I'd think they'd cope well with light aluminum cnc.
