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.
Solid 8mm lead screw. Will be a nice improvement on my z axis.
Great quality product at a reasonable price.
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.
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
