The Mighty Bolt base locked onto my track without any wobble, which is exactly what I needed for strapping down my crate. I've had other mounts rattle loose on rough water, but these stayed put all day.

Bought these to add tie-down points to my track system and the Mighty Bolt base locked in solid on the first try. No wobble at all once tightened down, even with a loaded crate strapped in.

Slid these onto my GearTrac to hold a cooler down and the Mighty Bolt base feels solid, no wobble at all. Only thing is the bolts could be a touch longer for thicker track, but they snugged up fine once tightened.
