Brass Coupler (2-2.3mm)

The Brass Coupler (2-2.3mm) is a tiny rigid shaft coupler made of brass with a 2 mm bore on one end and a 2.3 mm bore on the other. It joins very small shafts, for example a micro motor shaft to a thin rod, axle or drive shaft, with screws on each side clamping the shafts in place. It suits micro robots, RC models and small mechanisms where space is tight.

What's in the Box

• 1 × brass coupler, 2 mm to 2.3 mm

Tip: The two bores differ by only 0.3 mm, so test-fit each shaft to find the right end before tightening. Use a small, well-fitting screwdriver or hex key and tighten gently, as thin shafts and tiny screws are easy to damage.
