A brass hex coupler is a type of coupling device that connects two shafts together, allowing torque to be transmitted from one shaft to the other. It is made of brass, a metal alloy composed of copper and zinc, which has good corrosion resistance, high thermal conductivity, and is relatively easy to machine.
The "hex" in the name refers to the shape of the coupler, which has a hexagonal profile. This shape allows for a secure connection between the shafts, as the flat sides of the hexagon provide a firm grip that helps to prevent slippage and ensures efficient power transfer.
Brass hex couplers are commonly used in various mechanical applications, such as robotics, automation, and hobby projects. They come in different sizes to fit different shaft diameters and lengths, and they can be used to connect shafts on DC motors, gearboxes, and other mechanical components.. Featured By RoboticsBD.
