PC-Blue Aluminum Alloy Coupling 5x8MM for 3D Printers and CNC Machines

The Blue Aluminium Alloy Coupling 5×8 MM for 3D Printers and CNC Machines is lightweight coupling and exhibits more strength in class. This is made up of HE-30 grade aluminium. This type of couplings are very common and found in the wide range of CNC Machines. Please note that the bore diameters of this product are as d1=5 mm and d2=8 mm. They are available in fancy blue colour which in turn will make your machine look good.

They can firmly hold the shaft of the motor and other peripherals with the help of Grub Screws which can be tightened rigidly by using Allen Key which we have included in this product pack. Aluminium couplings are found in 3D Printers, CNC machines and other DIY projects to couple Stepper motors and 8 mm rods/threaded rods/precision trapezoidal rods.
