Product Description

Zinc‑plated 5/16-18 x 6" carriage bolt (round/domed head with square neck) — full thread, steel/low‑carbon or medium‑carbon material per vendor spec (ASME B18.5 / A307 / Grade 2/5 variants offered). Designed for wood‑to‑wood or wood‑to‑metal fastening where the square neck locks in a square hole to prevent bolt rotation; zinc plating provides general corrosion resistance for indoor and light outdoor use. Sourced wholesale unit pricing on comparable listings ranges roughly $0.40–$0.54 each (bulk purchase); a competitive single‑piece local resale price for Dayton, IA 50530 would be $1.49 each (single‑unit retail), which reflects typical small‑quantity retail markup above bulk distributor unit costs while remaining competitive with local hardware pricing.
