It's not a very robust solution if you're using it to cantilever the gearbox off your frame rail. Especially since you need to be super careful about how much you torque it. We used PEM nuts when we did Delrin side plates.

You also can't effectively prevent loosening due to vibration since you can't use loctite and nylon patch screws don't mix with threads in Delrin.
