Power up your larger timber projects with serious holding strength using our 1/2" Hex Head Lag Screws from Cutting Edge Metals. These heavy-duty lag bolts are offered in two practical finishes—zinc plated for reliable corrosion resistance and a clean professional appearance, or unfinished plain steel for a raw industrial look that develops natural patina over time.The 1/2" diameter delivers excellent load-bearing capacity for medium to heavy structural applications, making these screws perfect for mounting robust brackets to beams, securing barn door tracks, joining thicker timbers, assembling heavy furniture, or anchoring details in pergolas, log cabins, and post-and-beam construction. Choose from lengths 1-1/2", 2", 2-1/2", 3", and 4" to get the exact penetration your job requires.The hex head design allows for easy, high-torque installation with standard wrenches or our matching hex head sockets—quick, secure, and free of stripped heads.Available Lengths (All In Stock):
1-1/2" — Suitable for lighter structural attachments and thinner material
2" — Versatile standard length for bracket mounting
2-1/2" — Added grip for medium-duty connections
