Simple Tool

I have frequently ranted about the importance of securing set-screw types of propeller hubs to motor/gearbox shafts. Well, attached is a picture of a tool that makes it easier.

While it appears to be just another T-handle allen wrench, it has a special hex shape that allows it to deliver higher torque with less risk of stripping the hex on the screw. If you have never stripped the hex on a hex head set screw (especially with a ball end allen wrench) -- especially on a propeller hub -- you just haven't lived. When this happens, removing the damaged screw is nearly impossible without destroying, at the very least, the spinner, and often, much more.

This tool is available at:

While you are at it, you can purchase metric set screws in bulk and low strength Loctite.

Happy Landings,

Don

Good tip Don. The hex drivers sold for model helicopters are also high quality and resist gauling set screws. I use them on all my high(er) torque requiring needs.
