5/16" X 2" ONE WAY SCREW STEEL FINISH BLACK
½” X 2-½” HEX LAG SCREW, ZINC PLATED
Engineered for robust fastening in wood and other soft materials, these 1/2” x 2-1/2” hex lag screws provide exceptional holding power. The zinc plating offers reliable corrosion resistance for indoor and outdoor applications, while the hex head design allows for easy installation with standard tools. Ideal for construction, framing, and heavy-duty woodworking projects.
- Low Carbon Steel
- ASTM A307 / SAE J429
- Zinc Plated (ASTM B633)
- Wood Construction & Framing
These hex lag screws are forged from low carbon steel, providing a balance of strength and durability suitable for a wide range of fastening applications. Manufactured in compliance with ASTM A307 and SAE J429 Grade 2 specifications, they feature a minimum tensile strength of 60,000 psi. The screw's coarse thread is designed for superior grip in wood, while the zinc plating, applied per ASTM B633 standards, creates a protective barrier against rust and corrosion, extending the fastener's service life in various environmental conditions.
Primarily used to fasten heavy lumber and lag timber to other wooden members, these screws are a staple in the construction and framing industries. Their robust design makes them perfect for securing deck frames, attaching ledgers to structures, and assembling outdoor playsets or retaining walls. The hex head enables high-torque application using a wrench or socket, ensuring a tight, secure connection that surpasses the holding power of standard screws. They are a go-to choice for contractors and fabricators in the Los Angeles area.

How to Measure
Lag screws are measured by their diameter (shank thickness) and length. The length is measured from the underside of the hex head to the tip of the screw. The hex head size corresponds to the screw's diameter and determines the required wrench or socket size.
Example: To order this product, specify '1/2" x 2-1/2" Hex Lag Screw, Zinc Plated'.
