Should we be using more screws? 🤔 #framing #carpentry #testing

What happens here

For the bending resistance test, a deck screw, a structural screw, and a nail are each partially driven into different spots on the piece of wood, leaving a significant portion of their shafts exposed. A hammer is then used to strike the exposed shafts of each fastener repeatedly to bend them. The video shows text overlays indicating that the deck screw withstood 1.5 bends, the structural screw bent 2.5 times, and the nail broke immediately with a single strike, demonstrating clear differences in flexibility and durability.

Goal: Compare the bending resistance of deck screws, structural screws, and nails.

Tools and materials

  • Hammer — Striking and bending the fasteners
  • Piece of Wood — The base material into which the fasteners are driven
  • Safety Glasses — Protecting eyes from impact during hammering
  • Deck Screw — The fastener being tested for bending resistance
  • Nail — The fastener being tested for bending resistance
  • Structural Screw — The fastener being tested for bending resistance

What they say

Hide

We got nails, structural screws, and deck screws. Both screws hit about three and a half tons. The nail didn't even hit a ton.
