This trapezoidal screw nut is great to get linear actuation from a trapezoidal screw. It comes with mounting holes to mount your load or platform. The screw nut combination can be used to convert the rotational movement of a motor(Stepper, DC, Servo Motor) to linear motion.
Normal Threaded rod is not designed for accurate positioning — it’s primarily designed to be a fastener. You can have issues with backlash, wobble, and they usually aren’t even perfectly straight — not to mention they gunk up easily with dirt and grime. In other words, you’ll never see a threaded rod on a commercial machine.
Whereas Lead screws are precision machined components used for pretty much all proper CNC equipment. They have almost no backlash, they’re perfectly straight, and they allow for higher load transfers without jamming. Perfect for 3D Printers and CNC Machines.
Note: This is only the screw nut. The Lead Screw is not included and should be bought separately.
