1/4" X 2-1/2" HEX LAG SCREW, ZINC PLATED
Engineered for strong wood-to-wood and metal-to-wood connections, our 1/4" x 2-1/2" Hex Lag Screws provide reliable holding power for construction and framing projects. The hexagonal head allows for high torque application with standard tools, while the zinc-plated finish offers moderate corrosion resistance.
- Low Carbon Steel
- Conforms to ASTM A307
- Zinc Plated (ASTM B633)
- Wood Construction & Framing
This hex lag screw is manufactured from low carbon steel, providing the durability required for general construction and framing. It's designed to meet the performance requirements of ASTM A307 Grade A, ensuring reliable tensile strength for light to medium-duty applications. The coarse thread design provides excellent grip and pull-out resistance in wood, while the hexagonal head is ideal for installation with standard wrenches or sockets, allowing for secure tightening and simplified MRO tasks.
Commonly used in both new construction and industrial MRO projects, these zinc-plated lag screws are ideal for fastening heavy lumber, mounting machinery to wood floors, and other structural wood applications. The zinc coating provides a protective barrier against moisture, making them suitable for interior and some exterior environments where corrosion is a concern. They are a staple for contractors, fabricators, and maintenance crews in the Los Angeles area requiring dependable construction hardware for same-day pickup.

For projects requiring enhanced protection against weather and moisture, such as coastal construction, hot-dip galvanized and stainless steel options are also available through special order.
How to Measure
Lag screws are specified by their nominal diameter (shank diameter) and their length. The length is measured from directly underneath the flat bottom of the hex head to the tip of the screw.
Example: 1/4" x 2-1/2" Hex Lag Screw specifies a screw with a 1/4-inch diameter and a 2-1/2-inch length from under the head to the tip.
