A surgical end effector that includes a channel that is configured to operably support a surgical staple cartridge therein and an anvil that is movable between an open position and a closed position. A rotary driven firing member is configured to move axially between a starting position and an ending position. The rotary driven firing member includes at least one anvil engagement member that is configured to engage the anvil and at least one channel engagement member that is configured to engage the channel. The anvil engagement members may differ in size and length from the channel engagement members. The channel engagement members may have different channel engagement surfaces thereon that are formed at angles relative to each other.
