Anchor bolts are embedded into a concrete masonry unit wall with a specified minimum clearance and grout cover around the anchor diameter. The embedment length varies based on the bolt diameter, requiring four inches for a half-inch diameter, five inches for a five-eighths-inch diameter, and six inches for a three-quarter-inch diameter bolt. An eight-inch concrete masonry unit wall requires a five-and-three-eighths-inch embedment when utilizing a three-quarter-inch diameter bolt. Wall reinforcing is omitted from the section for clarity.
