    No worse than what you'd get from McMaster

    This lead screw works for me. It's pretty darned straight most of the time, but not perfect. But then again, when you buy leadscrews from McMaster, you're also going to get a little bow in theirs. I would just get these screws because they match up perfectly with the other products readily available at OpenBuilds.

    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.
