Another thing:

Yous guys and your set screws... geesh!

A set screw looks like a small threaded shaft with one end that is kinda pointy and the other end HAS NO HEAD ON IT! The non-pointy end with no head has a socket in the end so that you can turn it with a wrench.

If you see any of these menacing screws lying around your shop, get rid of them!

There are three types of machine screws that some of you may be thinking are "set screws".

A SOCKET HEAD CAP SCREW is a machine screw with a head on it that has a socket for an allen wrench. This head looks like a stubby cylinder.

A BUTTON HEAD SCREW is a machine screw with a flatter, rounded head on top of a screw. This head also has a socket on it for an allen wrench.

A FLAT HEAD SCREW is a machine screw with a cone-shaped head that fits down into a counter-sunk hole (not counter-bored, that's a hole for the socket head cap screw). This cone shape also has a socket on it for allen wrenches.

So, now you know the deal. Talking about set screws is like nails on a chalkboard to many of us.

The screws on the side of the SPI gearbox couplings are socket head cap screws... not set screws.
