6.35mm X 12mm Aluminum Flexible Shaft Clamp Coupler – CNC.BZ – 6.35 X 12 Nema

If you’re messing around with CNC machines, 3D printers, or any kind of motor setup, these couplers come in handy.

This one’s from CNC.BZ, and it’s a 6.35mm (that’s 1/4 inch) to 12mm flexible shaft clamp coupler.

It’s made of aluminum, so it’s lightweight but plenty strong for most applications.

The model number is 6.35mm x 12mm, and the MPN is 100102 for reference.

It’s brand new, in the original packaging.

These are great for connecting a motor shaft to a lead screw or another rod, especially if there’s a little misalignment—the flex helps take up the slack.

Common for Nema motors and similar setups.

Simple, solid, and does exactly what it’s supposed to.

If you need a spare or just building a project, grab one.
