Slug anchor is another name for which type of anchor?

• A. Deadman
• B. Cross-plate
• C. Expansion
• D. Screw

Answer: (A)

A slug anchor is a buried earth anchor, which is essentially the same idea as a deadman. A deadman uses a heavy piece of material (like a pipe, plate, or timber) buried in the ground and backfilled to create resistance against pulling loads. The term slug anchor comes from that same concept—the anchor relies on the mass of the buried slug (the metal piece) and soil grip rather than expanding, screwing in, or bearing on a plate in masonry. That makes it match the deadman, not the other types. The expansion anchor, screw anchor, or cross-plate anchor all work through different mechanisms (expansion in a hole, threaded engagement, or a plate-based grip), which is why they aren’t the correct fit.
