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.

For instance, consider a scenario where a construction project has specified a load-bearing requirement of 10,000 pounds for a particular application. A tolerance of 1% translates to just 100 pounds, a seemingly small figure that could lead to catastrophic failures if not properly managed. This highlights the importance of using high-quality materials that conform to stringent industry standards.
