Compare and Conclude Test Results

What happens here

After both shear tests are complete, visually inspect the failed wood pieces and their respective fasteners. The presenter shows the two failed assemblies side-by-side. He indicates that the nail held but bent significantly, failing at approximately 1 ton of force. He then points to the structural screw, noting that it snapped, but withstood approximately 4 tons of force before doing so. The clear conclusion drawn is that while both fasteners eventually failed, the structural screw significantly outperforms the nail in shear strength, demonstrating four times the resistance in this specific test.

Goal: Determine which fastener performed better in shear strength.
