Fits JKM 42 Linear Stepper Motor JK42HS34-1334 with Lead 4mm Not for regular Trapezoidal Screw with Lead 8mm! Body size is bigger, than used regular Prusa 3D printers.

I ordered this item because I thought that it will fit T8 trapezoid lead screw, but it is intended for smaller diameter lead screw (6-7mm). Besides that little mistake on my side, part is of good quality.

These are not the pretties nuts for lead screws: they are dinged and scratched and very rough on the outside. However, they are machined just fine where it counts, and the threads work well on the lead screws, and they will likely continue to function as needed.

fits JKM 42 Linear Stepper Motor perfectly. You can use two of these with a spring in the middle to make an anti-backlash nut. You can also use it as a replacement when the original nut of the stepper gets worn out

It has good quality, it fits good on a Screw.

tendria que decir q varilla se necesita para usar

ok buen producto

Good working.....

perfekt

Nuts were not the good size. I made an error during my order. It's only my fault.
