Ring Shank
A ring-shank fastener has concentric ridges along the shank that increase withdrawal resistance compared with a smooth-shank nail.
In Detail
Why Contractors Use It
Ring-shank nails hold subfloor, roof sheathing, and siding more securely because the ridges resist pull-out after the fastener is driven. That makes them especially useful in assemblies prone to movement or uplift.
They cost more and are harder to remove, but the gain in holding power is why many builders prefer them for squeak-resistant subfloors and exposed sheathing.

Structural Screw
A structural screw is a code-evaluated screw engineered for load-bearing wood connections, with published values for shear, withdrawal, and specific substitution conditions.
Uplift Resistance
Uplift resistance is the ability of a connection or structural assembly to resist forces trying to lift one part of the building away from another, usually due to wind suction.
