5/16 X 2 Hex Lag Screws
Engineered for heavy-duty wood construction, our 5/16 x 2 Hex Lag Screws provide superior holding power for framing, decking, and structural wood-to-wood connections. The hexagonal head allows for high-torque installation with a standard wrench or socket, while the coarse threads ensure a secure grip in lumber.
- Low Carbon Steel
- ASTM A307 Compliant
- Hex Head for High Torque
- Heavy-Duty Wood Construction
These 5/16 x 2 Hex Lag Screws are manufactured from low carbon steel, providing the strength and durability required for light-duty structural applications. Compliant with ASTM A307 standards, these fasteners offer reliable performance with a minimum tensile strength of 60,000 psi. The gimlet point and coarse thread design allow for easy starting and powerful pull-out resistance in wood, making them a staple for commercial construction and MRO projects. They are typically supplied with a zinc-plated finish for moderate corrosion resistance.
Ideal for projects requiring a strong, reliable wood fastener, hex lag screws are widely used in framing, ledger board attachment, and securing heavy equipment to wood bases. Their robust design makes them suitable for both indoor and outdoor applications where high load capacity is needed. From constructing decks and pergolas to assembling large wooden crates and machinery skids, these industrial-grade lag screws are a versatile solution for contractors, fabricators, and maintenance professionals in the Los Angeles area.
