DMiotech 2-Pack 6mm Inner Diameter Flange Shaft Coupling – Rigid Guide Support, For RC Motors & Stepper Motors, Sky Blue

About This Product

If you're building or repairing RC models, 3D printers, or CNC machines that use stepper motors, this DMiotech flange coupling set is a solid little upgrade.

You get two couplers with a 6mm inner diameter – that's the size of the hole for your motor shaft – and the total height is 15mm with a base diameter of 28mm.

The cylinder outer diameter is 15mm, so it's compact but sturdy.

They're made from aluminum alloy that's heat-treated and electroplated, so they're durable, corrosion-resistant, and hold up to vibration without deforming.

The flange design lets you fix the shaft to a plane surface, making it easy to mount other parts directly to the shaft.

Each coupler has double connection points with screws that tighten at a 90-degree angle to hold everything firmly – no wobble or separation during operation.
They work great for stepper motors, RC motors, and model shaft connections.

Just double-check your shaft size before buying – these are for 6mm shafts only.
Comes with fastening screws, but you'll need your own M4 hex wrench.
A good, affordable set for precision builds.
