2 Sets Snap Lock Automatic Spring Cold Rolled Steel + Nylon

These little items are perfect. The axle hole is 2mm "clearance", which means that they fit on a 2mm shaft without binding and no "play". They are also of a good quality and really good value for money. I actually ordered these in error since I needed a flexible coupler, but these items have found other uses: I printed a PLA (plastic) fan-blade, but it is difficult to connect a plastic item to a motor with only a short 2mm shaft. Solution? Print the fan with a 9mm centre hole in the hub and you can easily fix this coupler into the centre of the hub of the fan blade with a dab of super-glue. Now my 3D printed fan blade can be connected to the motor with perfect precision, high strength and no limitations with the motor short shaft, or trying to fix a 2mm shaft into plastic. I will buy more of these because I have several other 3D projects that need to be connected to small model motors, including an ornamental wind generator. I am 100% satisfied with my purchases, and also 100% satisfied that they have other uses in model-making. Harry L

Received today the above chime door bell but it is not clear how to use it if there is only the indoor part for placing into the plug is delivered to me but there is no outside doorbell for pairing with this device. Kindly advise what to do and why the outside doorbell is missing?

When they arrived I thought omg the things that I bought it for weren't going to you hook on to it as it doesn't look hooked enough but it does perfectly

The product is not stainless steel, it is galvanized...

Very small item. Very expensive for its size

Great product thanks very much

Thank you. Just as seen in picture.

Smaller than expected, but useful.
