You miss-understand, the screws are the same as yours (four short lug screws), but the hole for them goes straight through the Volcano case, you can look through the lug holes and out the other side of the case, with my black themes you couldn't do that, the holes stopped, so if a screw got stuck in there, it was near impossible to get out!
The APbands screws would simply not screw into the Volcano, the four rep ones fit the Volcano easy as pie. My old black themes was a pain in the ass, you couldn't swap between a steel bracelet and a strap, due to the lug screws being tight and stripping easily, rep or APbands
