When notching or drilling in the top plate of a load-bearing wall, the metal tie should be a minimum of how many gauge?

The correct answer is 16 gauge because it is the minimum thickness recommended for metal ties used in load-bearing wall construction. Metal ties provide critical support and structural integrity, especially when notching or drilling through the top plate of a load-bearing wall.

Using a 16 gauge metal tie ensures sufficient strength and resistance to deformation, which is vital when the wall is carrying loads. Thicker gauges offer added strength, but 16 gauge strikes a balance between structural reliability and workability.

In residential construction, adherence to specific gauge standards helps maintain safety and building code compliance. An insufficiently thick metal tie could compromise the wall's strength, leading to potential structural failure. Understanding these requirements is crucial for all carpenters and builders involved in load-bearing construction.
