Anchor Bolt

Metal fasteners embedded in masonry or concrete to secure structural elements like sill plates, ledger boards, or equipment bases. In masonry construction, anchor bolts are set in grout-filled cores of CMU walls or cast into bond beams before the grout hardens. Ontario building codes specify anchor bolt requirements for wood-frame construction connections to masonry foundations, typically requiring 1/2-inch diameter bolts at maximum 6-foot spacing. Retrofit anchors using epoxy or mechanical expansion allow attachment to existing masonry without compromising structural integrity. Proper anchor bolt installation is critical for transferring lateral loads between wood framing and masonry foundations.
