Final answer:
Foundation anchor bolts should extend a minimum of 7 inches into masonry or concrete, with the depth determined by building codes.
Step-by-step explanation:
Foundation anchor bolts should extend at least 7 inches into masonry or concrete. These bolts play a crucial role in ensuring the stability and safety of a building structure. They secure the sill plate, which is the lowest framing component of a building, to the concrete or masonry foundation, providing resistance to seismic activity and uplift forces.
It is important for building codes and specifications to be followed precisely, as the depth of the bolt embedment is essential to the anchor's performance. The specific number of inches can vary depending on building code requirements and the design parameters of a particular project, but 7 inches is a common minimum embedment depth for residential applications.
