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.
In Detail
Why the Label Matters
Not every heavy-looking screw is structural. A true structural screw is backed by testing, installation instructions, and evaluation data that support its use in real structural connections.
That distinction is what separates it from commodity deck or multipurpose screws, which may look similar but fail in brittle ways when overloaded.
