Blue Aluminum Alloy Coupling 5x5MM for 3D Printers and CNC Machines

The Blue Aluminum Alloy Coupling 5x5MM for 3D Printers and CNC Machines is lightweight coupling and exhibits more strength in class. This is made up of HE-30 grade aluminum. 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=5mm and d2=5mm. They are available in fancy blue color 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. Aluminum couplings are found in 3D Printers, CNC machines and other DIY projects to couple Stepper motors and 8mm rods/threaded rods/precision trapezoidal rods. Features : Exhibits good strength.
