About
Hex Lag Screws , also called Lag Bolts , are substantial hex head screws designed for high-load wood-to-metal or wood-to-wood fastening. These screws are extremely durable and can support a much heavier load than typical wood or sheet-metal screws, making them ideal for structural framing, deck construction, or mounting heavy fixtures such as flat-panel TV brackets. To install, always pre-drill a pilot hole to prevent splitting the wood due to the larger diameter of the screw. We offer lag screws in both stainless steel and zinc-plated steel depending on your application needs—zinc-plated for maximum strength and stainless for corrosion resistance in outdoor or marine environments. Common Uses: Lag screws are commonly used for structural framing, deck supports, equipment mounting, and other heavy-duty wood connections. Note: Lag screw lengths are measured from under the head to the point of the screw. .mb-accordion details { margin: 8px 0; } .mb-accordion summary { cursor: pointer; font-weight: 600; color: #00429a; } .mb-accordion summary::-webkit-details-marker { display:none; } .mb-accordion summary:after { content:"▸"; margin-left:6px; } .mb-accordion details[open] summary:after { content:"▾"; } .mb-accordion p { margin: 8px 0 0; } What are lag screws used for? For high-strength fastening—deck framing, wall/TV mounts, and wood-to-metal connections—when through-bolting or a nut isn’t practical. Are “lag bolts” and “lag screws” the same thing? Yes. The terms are used interchangeably for large hex-head fasteners with coarse lag threads. Do I need to pre-drill? Yes. Always drill a pilot hole slightly smaller than the screw’s diameter to prevent splitting and ensure straight installation. Stainless vs. zinc-plated—what’s the difference? Zinc-plated steel typically offers higher tensile strength; stainless provides superior corrosion resistance for outdoor or wet environments. { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question"
