I love that this pair of anti-play nuts come in separate bags within the larger ones, especially as I only need one at the moment. I was impressed by the very tight fit between the two halves. This fit is critical as any gap between the top and bottom contact flanges represents the play this nut will have. Because the fit is so tight, there's no noticeable play between the two halves, which is perfect. I used this kit to reduce lead screw play on my longer lk4 pro. The factory nut was actually pretty good, but that eliminates another source of error and discrepancy. I reused the factory assembly parts so this was a direct replacement and an easy replacement.
