The 8mm Acme Anti-Backlash Nut Block is a great choice for many projects requiring lead screw linear motion.

The pitch and diameter are a perfect combination of high torque and speed. This screw is suitable for most machine designs and has quickly become a standard for builders and makers.

This metric fastener features a reduced head height of 1.5mm or less, allowing it to sit nearly flush against surfaces to prevent interference with moving parts in tight clearances. Its primary function is to secure mechanical components together without obstructing adjacent motion paths. It is designed for precise mechanical builds and structural assemblies with limited overhead space, such as securing brackets, plates, and V-slot wheels in 3D printers and CNC machines to avoid gantry or belt collisions. Additionally, it integrates into aluminium extrusion T-slot profiles and compact electronic devices to maintain space efficiency.

These high-precision metric aluminum spacers are engineered for mechanical assemblies requiring consistent axial clearance and rigid structural support. Primarily utilized in CNC machinery, 3D printers, and robotic gantry systems, these spacers provide the necessary offset for our V-slot linear rails, motor mounts, and PCB standoffs.

Chrome Steel Lock Nuts provide strength, a Nylon insert prevents the Nut from loosening over time or with vibration.

For your convenience these are sold individually, so add as many as you need.
