Whether you’re building a sturdy wooden deck, assembling heavy-duty furniture, or securing outdoor structures, you need fasteners that won’t let you down. These 6mm M6 A2 stainless steel hex head lag bolts (DIN571 standard) are designed for wood applications where strength and corrosion resistance matter. Made from 304 stainless steel (Grade A2), they resist rust and oxidation even in humid or coastal environments. The hex head lets you drive them easily with a wrench or socket, and the sharp wood thread bites deep into timber for a secure, long-lasting hold. Each pack gives you 10 pieces – just the right amount for small to medium projects without overbuying.
304 Stainless Steel (A2 Grade) – Excellent corrosion resistance, ideal for indoor, outdoor, and marine-adjacent applications. No rust spots after rain or humidity.
DIN571 Standard Hex Head Lag Bolt – Precision manufactured to meet German industrial standards, ensuring consistent thread geometry and reliable performance.
Sharp Wood Screw Thread – Self-tapping design cuts into wood cleanly, reducing splitting and providing maximum grip in softwood and hardwood alike.
Easy Hex Drive System – Use a standard hex socket, wrench, or impact driver. No cam-out or stripped heads like Phillips drives.
Untreated & Pure Stainless Steel – No coating to chip or wear away; the entire bolt is solid A2 stainless, so the protection never fades.
Versatile for Many Projects – Perfect for fencing, garden furniture, timber framing, shelving, gate hinges, and DIY repairs.

Yes, they are made from 304 stainless steel (A2 grade), which offers excellent corrosion resistance. While no metal is 100% rust-proof in extreme conditions (e.g., constant saltwater immersion), these bolts are perfectly suited for outdoor furniture, decks, and general humid environments. For typical residential use, you won’t see rust stains for many years.
For softwoods like pine, a pilot hole about 80% of the bolt diameter (4-5mm) is recommended – especially near edges to prevent splitting. For hardwoods (oak, maple) we strongly advise drilling a proper pilot hole and optionally countersinking the head. The sharp thread helps, but pre-drilling ensures a cleaner result and easier driving.
Each pack contains 10 hex head lag bolts only. No nuts, washers, or other hardware are included because these are wood screws – they thread directly into timber, not into a nut. If you need to fasten two pieces of wood together, these bolts alone (with a pilot hole) work perfectly.
Absolutely. 304 stainless steel is the preferred material for pressure-treated wood because it resists the corrosive chemicals (like copper) used in modern treatments. Unlike ordinary zinc-coated screws, these A2 bolts won’t develop white rust or black streaks when in contact with treated lumber.
You’ll need a hex socket or box-end wrench sized for the M6 hex head (typically 10mm across flats). A ratchet with a deep socket makes driving easier, especially in tight spaces. An impact driver with a hex bit also works great for larger batches.
