I would caution against over-tightening the set screw, but these work great for the 8mm lead screws.
Lead Screw Tension Nuts
Love these! I was able to replace the 8mm shaft collars with these much more appropriate tension nuts to keep lead screw end play in check. Can't believe I didn't see these before, but I'm so glad to have them now! Very nice quality machining & fit with generous size set screw.
Went right on
It went on great. I don't have a motor hooked to the other side yet so I couldn't seat it properly yet but it still holds the lead screw nicely
I removed the stop caller and replaced it with the tension nut then a precision spacer then the bearing. Locking the tension nut placing pressure on the tension nut.
Superior solution to locking nut in "compression" lead screw builds and a must have in tension builds. Will be converting all four of my lead screws to tension with these nuts and thrust bearings.
