šŸ”© M8 A2 Stainless Steel Hex Head Lag Bolts – DIN571 Wood Screws (10-Piece)

If you're tired of rusting screws ruining your outdoor furniture or deck, these M8 hex head lag bolts are a solid upgrade. Made from A2 (304) stainless steel, they hold up to rain, humidity, and even pressure-treated lumber without corroding. The external hex drive lets you sink them with a wrench or impact socket — no cam-out like Phillips heads. Whether you're building a pergola, attaching ledger boards, or assembling heavy wooden planters, this 10-pack of DIN571 wood screws gives you clean, reliable fastening from the first turn.

✨ Why These M8 Hex Head Wood Screws Work Better

Genuine A2 (304) stainless steel – Won't leave ugly rust streaks on your cedar or redwood projects. Perfect for decks, fences, and garden structures.

DIN571 standard hex head design – Use a 13mm wrench or socket (common for M8 hex). The tall head gives you plenty of bite even with gloved hands.

Sharp wood screw point & deep threads – Bites quickly into softwood and hardwood alike. Reduced splitting compared to blunt lag bolts.

Metric M8 x approximate length? (length not specified) – Typically DIN571 M8 lag screws come in lengths from 40mm to 120mm. Please check your required length before ordering – we offer various sizes. Contact us if you need a specific length.

10 pieces in protective packaging – Comes in a plastic bag/carton, easy to store or take to the job site. No loose hardware mess.

ā“ Frequently Asked Questions

What length are these M8 hex lag bolts?
This specific listing is for a 10-pack of M8 stainless steel hex head wood screws. Length varies by the option you select. Please check the dropdown or variant selector for exact millimeter length (common lengths include 50mm, 60mm, 80mm, 100mm). If you don't see your needed length, contact us – we can supply other sizes.
Do I need a pilot hole for these M8 wood screws?
For softwoods like pine or fir, you can often drive them directly without pre-drilling. For hardwoods (oak, hickory) or near board edges, we strongly recommend drilling a clearance hole about 6-7mm in diameter. That prevents splitting and makes driving much easier. A countersink bit also helps the hex head sit flush.
Are these really rust-proof for outdoor use?
Yes. 304 stainless steel (A2 grade) offers excellent corrosion resistance in normal outdoor conditions – rain, snow, humidity. They will not develop orange rust like zinc-coated or plain steel screws. However, if you're near saltwater (coastal areas with direct sea spray), consider upgrading to 316 (marine grade) stainless. For most decks, fences, and garden projects, these M8 304 lag bolts are more than enough.
What tool do I need to drive these hex head lag bolts?
Use a 13mm wrench, a 13mm socket with a ratchet, or a 13mm hex socket on an impact driver. Do NOT try to use a screwdriver or a regular drill bit – the external hex design requires a wrench or socket for proper torque. An impact driver with a socket adapter works great for driving them into wood quickly.
Can I use these M8 lag screws for metal or plastic?
Not recommended. These are designed specifically for wood (timber, plywood, particle board). The thread pattern and sharp point are optimized to bite into wood fibers. For metal, you'd need a machine screw or self-tapping metal screw. For plastic, a standard thread-forming screw works better. Stick to wood for best performance.

āš ļø Note: Due to manual measurement and different screen displays, slight variations in color or size (±0.5mm) may occur. If you need a specific length not listed, please contact us before ordering.
