But the security skewers have been a real problem for me, mostly because the small tools (nothing more than an Allen key) don't provide a ton of leverage.
In my case, in line with other comments above, it is because the hub's axle was just a bit too wide for the stamped dropouts of the bike I was trying to set up. I'd screw down the cammed skewer as far as it would go, but it did not have enough grasp to stay in place. The security skewers however would clamp it tight.
