PART J - ANCHOR BOLTS
To fasten top plates to the top of concrete-block walls, you must use anchor bolts.
2-25. Spacing of Anchor Bolts. Anchor bolts should be spaced no more than 4 feet apart. Place a
metal lath in the second horizontal mortar joint from the top of the wall wherever you plan to install an
anchor bolt (Figure 2-27).
Figure 2-27. Placing metal lath
2-26. Installing Anchor Bolts. In the top course of the wall, place the bolts in the cores of the selected
blocks. Fill these cores with concrete or mortar, and extend the threaded end of the bolt above the top of
the wall (Figure 2-28, page 2-28). Attach the top plates to the anchor bolts after the mortar has set.
