There are a number of ways to keep the bolt from slipping, but most of them aren't really necessary ... friction is usually enough, especially if you place a large flat washer right under the bolt head.
T-track will work fine, but I'd recommend mounting it atop cleats out at the edges of the table, similar to the way I did mine:
Another simple, direct method is to simply clamp the fence to the table's overhangs. This too can be done in a number of ways: Quick Grips, short F-body clamps, or even ultra-short pipe clamps. One good arrangement is to make the far end pivot even after it has been locked down, and then adjust the near end until it's in the right position and then clamp it down. That's what I do with my fence: even when the far knob (nearest the camera, in this shot) is snugged down securely, I can still swing the fence end that's closest to me enough to make my final adjustment.
And that, BTW, is the main reason you won't use a miter slot very often even if you have one. To use the slot, you have to fiddle with BOTH ends of the fence simultaneously, so it will be parallel to the slot AND the right distance from the bit. No need to do all that if you use a sled: you just set the fence where it needs to be relative to the bit.
