This assembly consists of a treated 2x lumber nailer plate secured to a concrete tilt-up panel using 1/2-inch diameter by 10-inch long hot-dipped galvanized carriage bolts with a minimum yield strength of 36 ksi. The bolts are countersunk flush with the bottom of the nailer, with a nut and washer on top and an additional nut to secure the bolt to the plate. Fasteners are spaced at a maximum of 24 inches on center, with a tighter spacing of 12 inches on center required within 24 feet of each corner. Bolts must maintain a minimum 4-inch clearance from concrete pockets and are installed with a minimum 1 1/2-inch edge distance from the concrete face. The nailer must be number 2 or better Southern Pine, and countersinking is limited to a maximum of 3/4-inch depth.
