This picture is from a 3 year old 100 amp panel. The screw is in between the two breakers of the 100 amp main. Any idea why it is there or what it is for?

Different manufacturers use a variety of methods varying from bolts or screws to special clips. The one in the photo looks normal, and should be there.
