Sub panel installation

I am using a Square D 100A 20 space service panel as my sub-panel. My research shows I must isolate the neutral buss bar from the grounding buss bar.My concern is the bonding jumper between the neutral buss and the grounding buss.There is no way to isolate the two buss bars because the screws that hold both buss bars in place are utilizing tapped holes on the bonding jumper. I have not used the screw provided which grounds the bonding jumper to the box. I live in Columbus Ohio

You don't have a neutral bar and a ground bar, you have 2 neutral bars. The ground bar must be purchased separately. It takes a PK15GTA ground bar according to the label in your picture. No, you don't need the bonding screw. It will be thrown away on this installation.

I am understanding this much better now, thank you. I have installed circuit's before but never a sub panel. First post for this newbie to this site and I like it already.
