This EasyMech MS NEMA17 Shaft Coupling 5mm X 8mm is made up of hardened Mild Steel. The Mild Steel is much heavier and much denser material than the Aluminum.

The EasyMech Mild Steel NEMA Shaft Coupling is slightly cheaper than the EasyMech Aluminum Coupling but yet stronger than Aluminum coupling. Hence they are more rigid couplings.

This MS coupling is painted with the black color to make it corrosion resistant which also makes it more attractive in look. By careful installation and maintenance of couplings, substantial savings can be made to reduce maintenance costs and annoying downtime.

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.

Please note that the bore diameters of this product are as d1=5mm and d2=8mm.
