This TR8x2 brass trapezoidal metric lead screw nut is compatible with our 8mm diameter TR8x2 range of Precision Leadscrews. The diameter and pitch offer a great combination of high torque and speed capabilities, which is why it is one of the most used and popular leadscrew and nut combinations for 3D Printers, CNC machines, and other linear motion equipment. All high-end 3D printers make use of TR8x2 leadscrews for their Z-axis motion, resulting in consistent and accurate layer resolution and movement.

This brass nut features a round flanged surface with four M3 tapped holes, making mounting a breeze to the rest of your machine. The nut has a pitch of 2mm, with a single start, resulting in a lead of 2mm. This means that there is 2mm of travel per revolution of the leadscrew - or around 0.01mm per step of a 200-step stepper motor.

Typical Applications for the TR8x2 Metric Lead Screw Nut:

These nuts are an excellent choice for attaching a part or component like an extruder to a linear leadscrew, and allows you to control the linear motion of the part precisely with stepper motor rotations. This translates to near-perfect accuracy, without having to rely on belts that may stretch or snap under high torque loads.

This leadscrew nut is stocked to fit the TR8x2 500mm Leadscrew, the TR8x2 375mm Leadscrew, the TR8x2 300mm Leadscrew, as well as the TR8x2 200mm Leadscrew – which are all made to enhance the Z-Axis accuracy on 3D printers.
