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.

This high-quality aluminium 5mm x 8mm Flexible Coupling can be used to connect your stepper motor with a 5mm shaft to your 8mm lead screw.

Socket Cap Screws are high strength fasteners, with an Internal Hex or Allen drive style and cylindrical barrel-shaped head. The head diameter is typically 1.5 times or more, the diameter of the screw thread.
