I was looking at fasteners the other day, and came across a dryall-type screw labelled as a “laminating” screw….it had a size 8 shank, as opposed to size 7 for deck screws and size 6 for drywall screws. Anyone know what/how these are used, and if their purpose is, indeed, for laminating, what is it that the larger shank provides? Increased grip? Tensile strength? Never thought of laminating as requiring much tensile strength. Increased grip?

For laminating drywall. If going over existing drywall, these will grab and sink the head by threading into just drywall if you can't hit wood behind it. They work real good to attach 1/2 inch to 5/8inch, not so good for thinner rock.
*They work great for fastening underlayment to OSB subflooring, they will grab enough to countersink in particle board, wonderboard or any other underlayment.
