2. Expansion Screws These screws are designed for concrete or masonry walls. When installed, they expand and grip the surrounding material as the screw is driven into it, creating a robust anchor point.

A crucial aspect of drywall screws is their tensile strength and shear strength, which determine how well they can hold the weight of drywall panels without bending or snapping. Screws tagged with a specification such as 8% may indicate they have been tested to handle specific load requirements or meet certain building codes, showing they can perform reliably under stress.
