You don't need them at all, I don't even bother with them anymore. I believe they're 6mm screws if you so desire.

Ok. Those bolts should have been removed with an impact screwdriver. It gets them out almost everytime and they can be reused. Now, contrary to what you might have heard, these bolts serve a purpose. They align the brake disc to the hub assembly to reduce radial runout. Brake discs new or used have ring-groves on the surface due to machining and brake pad contact. When you mount the disc without the screws, there is a lot of play in the radial directions (up/down/left/right). That puts the ring-groves off centre, thus causing excess radial runout. This usually manifests itself as vibration under braking. Putting the bolts on centres and aligns the disc to the hub, thus preventing this from happening. If I were you, I'd replace them. They're cheap anyhow.
