Perfect fit
Just like the original knobs, they fit great. Just added some light oil to the threads before installing to add good protection against the weather.

They're decent
I bought these to try in place of the 8mm speed knobs TSO sells for 20 bucks a pair. They're much smaller, and the base isn't big enough, so I epoxied an 8mm fender washer onto the base and they work fine. Since they're quite a bit smaller diameter you won't be able to get as much grip torque, but that shouldn't be a problem using them on a multi-function surface with bench dogs.

Worked Well
worked well to attach our bike racks to our bikes. We did have to cut them off because they were longer than I realized when ordering (that was my fault not the knobs lol). The plastic knob has been very durable and they make it very easy to pull the racks off the bikes for transport.
