Description

Ever needed a single metric lag bolt in an odd size but didn't want to buy a bulk box? These M6, M8, M10, and M12 A2 stainless steel hexagon head lag bolts are sold individually, so you get exactly what your project calls for – no more, no less. Whether you're fastening a workbench leg, hanging a heavy shelf, or repairing outdoor furniture, these self-tapping wood screws drive cleanly into timber with a hex wrench or socket. The 304 stainless steel body resists rust and corrosion, making them a solid choice for both indoor and outdoor applications. Choose your thread diameter (M6/M8/M10/M12) and length from 30mm up to 150mm.

šŸ”© Why Choose These A2 Stainless Hex Lag Bolts?

Individual piece sales – pick exactly what you need – No wasted fasteners. Buy one M6x50mm lag bolt or ten M12x120mm – whatever your project requires.

A2 (304) stainless steel construction – Excellent corrosion resistance, oxidation resistance, and heat tolerance. Great for outdoor decks, garden structures, and humid environments.

Hexagon head with cross geometry (self-tapping) – The sharp wood threads bite aggressively into softwood and hardwood. Use a standard hex socket or wrench to drive them without stripping.

Wide metric size range – Thread diameters: M6, M8, M10, M12. Lengths from 30mm to 150mm. Perfect for furniture assembly, machinery mounting, timber framing, and DIY repairs.

Untreated natural finish – No plating to chip or wear. The solid stainless steel looks clean and performs consistently over years of service.

ā“ Frequently Asked Questions

Q: Do I need to pre-drill for these hex lag bolts?
A: For M6 and M8, a pilot hole is recommended (about 70-80% of the shank diameter) – especially in hardwoods like oak or maple. For M10 and M12, always pre-drill to prevent splitting and to make driving easier. Use a drill bit slightly smaller than the bolt's core diameter. Softwoods like pine may not need pre-drilling for smaller sizes, but it's still good practice.
Q: What tool do I need to tighten these hex head screws?
A: You'll need a hex socket or a wrench that matches the hex head size. Common hex head sizes for metric lag bolts: M6 head ~10mm, M8 ~13mm, M10 ~16mm, M12 ~18mm (always check the actual bolt as manufacturing tolerances vary). A ratcheting wrench or an impact driver with a socket makes quick work of driving them.
Q: Can I use these A2 stainless lag bolts outdoors in coastal areas?
A: Yes. A2 (304) stainless offers good resistance to rain, humidity, and even mild salt spray. For direct saltwater immersion or extreme marine environments, A4 (316) stainless is better. But for most decks, fences, garden sheds, and outdoor furniture, these 304 hex lag bolts will outlast regular steel or zinc-coated fasteners.
Q: Why would I buy a single bolt instead of a pack?
A: Many projects need just one or two specific sizes – replacing a broken lag bolt, mounting a new shelf bracket, or repairing a single hinge. Buying a bulk pack of 50 or 100 leaves you with leftover fasteners you may never use. Sold individually, you pay only for what you need, and you can mix different diameters and lengths in a single order.
Q: Are these bolts self-tapping? Do I need to pre-thread the wood?
A: Yes, they are self-tapping wood screws. The sharp tip and coarse threads will cut into wood as you drive them. However, "self-tapping" doesn't mean no pilot hole – for best results and to avoid splitting, a pilot hole is still recommended, especially for larger diameters (M10/M12) and hardwoods. The bolt will then follow the pilot hole cleanly.
