3/8" x 4" hex‑head lag screw for heavy‑duty wood‑to‑wood connections. Typical construction-grade versions are manufactured from carbon steel with coarse wood threads and a hex head for wrench or socket installation; common finishes include zinc‑plated, hot‑dip galvanized, and 18‑8 stainless for improved corrosion resistance. These fasteners are sold individually or in bulk (pack quantities and minimums vary by supplier) and require a pre‑drilled pilot hole for wood applications. Use for ledger boards, deck framing, retaining walls, and other structural wood fastening where a robust wood screw is required.
