🔩 Heavy-Duty 20PCS 3/8-16x6" Stainless Steel Lag Bolts – Built to Last

Whether you're building a backyard deck, securing heavy lumber, or tackling an outdoor furniture project, these 3/8-16x6" lag bolts give you the holding power you need. Made from 304 stainless steel, they resist rust and corrosion far better than regular screws. No more worrying about weather exposure or premature failure. With 20 pieces in each box, you'll have enough for medium to large jobs without constant trips to the hardware store.

✨ Why Choose These Hex Head Wood Screws?

Rugged 304 stainless steel – Superior corrosion resistance and anti-rust performance compared to ordinary screws. Perfect for outdoor and high-moisture environments.
Precise 3/8" diameter x 6" length – Ideal for joining thick lumber, deck framing, ledger boards, and heavy timber structures.
External hex drive – Works with a 9/16" wrench (not included). The hex head design allows high torque installation without stripping, giving you a secure, tight fit.
High-strength craftsmanship – Hardened and deformation-resistant. No eccentricity or easy breakage, even under heavy loads.
Value pack of 20 pieces – Comes in a sturdy box. Enough for multiple projects or one large assembly, saving you time and money.

❓ Frequently Asked Questions

Will these lag bolts rust if used outdoors or near saltwater?

These lag bolts are made from 304 stainless steel, which offers excellent corrosion resistance for most outdoor applications – including decks, fences, and coastal environments (though 316 would be better for direct saltwater immersion). For normal rain, humidity, and weather exposure, they will far outlast regular zinc-coated or plain steel screws.

What tools do I need to install these hex head screws?

You'll need a 9/16" socket wrench, combination wrench, or an impact driver with the correct hex socket. Pilot holes are strongly recommended for 6" lag bolts – use a 1/4" or 17/64" drill bit for softwood, or slightly larger for hardwood. Pre-drilling prevents wood splitting and makes driving smoother.

Are these screws fully threaded or partial thread?

They are partial thread lag bolts. The unthreaded shank near the head allows the two pieces of wood to be drawn tightly together, while the threaded section bites into the far piece. This design gives maximum clamping force for structural joints like deck beams or ledger boards.

Can I use these 3/8-16x6" lag bolts for indoor furniture projects?

Absolutely. While they're heavy-duty, they work great for large indoor workbenches, shelving units, or wooden frames that require serious holding power. The stainless steel also gives a clean, professional silver look. Just make sure your material thickness accommodates a 6" screw.

How many pieces come in the box? Is it enough for a typical deck project?

You get 20 pieces. For smaller deck repairs, attaching a ledger board (every 16" spacing), or building a play structure, this quantity is sufficient. For large full-deck framing, you might need multiple boxes – but the value pack keeps costs low compared to buying individually at big-box stores.
