½” X 3” HEX LAG SCREW, ZINC PLATED
Engineered for strong wood-to-wood or metal-to-wood connections, the ½” x 3” Hex Lag Screw provides superior holding power for construction and framing projects. The zinc-plated, low-carbon steel construction offers reliable performance and corrosion resistance for MRO and general hardware applications.
- Low Carbon Steel
- ASTM A307 / SAE J429
- 60,000 PSI Minimum
- Zinc Plated (ASTM B633)
This ½” x 3” hex lag screw is forged from low-carbon steel, conforming to ASTM A307 specifications for light-to-medium duty fastening. It features coarse, deep threads designed to bite securely into wood, providing excellent pull-out resistance. The hexagonal head is engineered for high-torque installation with standard wrenches or sockets. A zinc plating finish, applied per ASTM B633 standards, provides a protective barrier against corrosion, making these screws suitable for a variety of indoor and some protected outdoor environments.
Primarily used in wood construction, these hex lag screws are ideal for fastening heavy lumber, mounting machinery to wood floors, and securing structural components in decks, fences, and retaining walls. Their robust design makes them a staple for MRO professionals, contractors, and fabricators in the Los Angeles area who require a dependable fastener for both new construction and repair work. The 3-inch length provides significant embedment for strong, durable connections in demanding applications.
