Screws or nails in dbl layer of OSB

Hello, I have a OSB plywood floor in my attic and its only 7/16" thick so Im adding another 7/16" thick layer on top to thicken it up and make it feel like Im not going to fall threw. Anyway, I already started screwing it together with coarse 1-1/4" drywall screws and some screws hold some don't they spin or strip out. My question is would fine thread drywall screws work better or would a certain kind of nail?

Pain in the butt but if you predrill the top piece it will pull the two pieces together instead trying to push the bottom piece away as it first grabs.

To keep it from stripping try using an adapter on your drill that's made for setting drywall screws.
Is this attic designed to hold all that extra weight? If not there's going to be a lot drywall damage down stairs over time.

Hope you slapping some construction adhesive between those sheets. It will sure help with the bonding.

When its all said and done there is usually more said than done

I agree, use construction adhesive between layers. Also, longer screws ran through into joists will solve stripping problem.
All the best to you and yours, Tom

Your 6ga, 1 1/4" drywall screws are too long, too skinny, and you're running them in too fast. Get some 8ga, 1" deck screws and install at low speed and all your problems will disappear. Yes on the adhesive.
