Bulk 3/4" Hex Lag Screws Low Carbon Steel Zinc CR+3

Heavy-Duty, Corrosion-Resistant Fasteners for Demanding Wood Connections

Take on your toughest woodworking, construction, and outdoor projects with our premium 3/4"-4.5 Hex Lag Screws, crafted from low carbon steel and coated with Zinc CR+3. These lag screws—often called lag bolts—feature a 3/4" diameter and approximately 4.5 TPI (threads per inch), providing exceptional holding power in wood and reliable corrosion resistance in moderate outdoor conditions.

The hex head design allows for easy installation using a wrench or impact driver, while the coarse threads and sharp point ensure maximum grip. Pre-drill pilot holes to prevent splitting and ensure proper alignment. These large-diameter screws are perfect for securing heavy beams, constructing substantial wooden structures, and tackling projects where strong, semi-permanent wood connections are essential.
