- ASTM A307
- Zinc Plated (ASTM B633)
- 60,000 psi min.
This hex head lag screw is manufactured from low carbon steel, conforming to ASTM A307 specifications to ensure consistent performance and reliability. It features a minimum tensile strength of 60,000 psi, providing the necessary clamping force for structural wood connections. The coarse, deep threads are designed for maximum engagement and pull-out resistance in wood, while the hexagonal head allows for high-torque installation with standard wrenches or sockets. The entire fastener is coated with a layer of zinc plating according to ASTM B633 for enhanced durability and protection against rust.
Ideal for contractors and fabricators in the Los Angeles area, these industrial-grade lag screws are essential for a wide range of applications. They are commonly used in deck framing, retaining walls, ledger board attachment, and securing heavy equipment to wood structures. Their robust design makes them a dependable choice for both new construction projects and MRO (Maintenance, Repair, and Operations) tasks requiring a strong, durable fastener for wood materials. We stock a full range for same-day pickup at our warehouse.
