i bought some of these for my boats, i have been looking everywhere for metal couplings, and they are not easy to find.

but these are NOT the best quality, they can vary in length 1mm, as to the sides. so its very loose fit. and i dont think they are super for high rpm.

The quality look good.
Great coupling for 3,15mm motor and 4mm shaft.
