TC Bolts - What Are the Alternatives?

I was going to ask what the alternatives was. If they're not doing it in two days, what are the other methods that would be more efficient or the different types of bolting? Well there's the twist off bolt which is that funny little ended bolt. I'm going to pick one. It's a spinal end, but this is again a torque based device. This is where the manufacturer has figured out the K factor and you'll be left with some raw steel when this thing snaps off. That one's essentially you twist it and then there's the fuse in the bolt that will snap off.
