The initial version will use a nut and a bolt to tighten the clamp, the 'final' version will have a threaded insert embedded into the clamp.
Keen to see where this gets to, but I would advocate the nut and bolt as a permanent feature. The threaded insert on my Garmin clamp has removed itself leaving me with an unusable garmin mount.
Interesting. The nut and bolt would be a bit more fiddly, but hadn't considered the durability benefits. I guess a component such as this isn't removed too regularly.
