What type of bolts are embedded in the foundation wall or concrete slab to secure the sill or bottom plate of a wall?

• A. U bolts
• B. L bolts
• C. J bolts
• D. S bolts

Answer: (C)

J bolts are specifically designed for embedding in concrete foundations or slabs to secure the sill or bottom plate of a wall. Their shape features a hook that allows them to grip into the concrete, providing a strong anchoring point for the structure above. When placed correctly, the straight part of the bolt is cast into the concrete while the hooked end is positioned to secure the sill plate, ensuring that the wall remains stable and prevents any lateral movement. This design facilitates a strong connection between the wall framing and the foundation, which is crucial for structural integrity. The effectiveness of J bolts in this application makes them a common choice in construction where solid anchorage is required to withstand various forces, including wind and seismic loads.
