Choose From a Range of Lag Bolt Sizes for Any Application
Lag bolts have a hex head for easy high-torque installation. You can use a wrench or socket for strong wood insertion.
They cut their own mating thread. Threading is usually 60% to 67% of the lag screw length measured from under the head to the tip of the screw.
Lag bolts are installed with a washer.
Available in both 18-8 and 316 stainless steel, they are resistant to weather and high-moisture environments. 316 stainless steel is a marine-grade material, which means it is corrosion-resistant even in the toughest saltwater environments.
Lag screws are available in multiple diameters (up to ¾ in.) and lengths to match project requirements.

Pro Tip: Apply anti-seize compound or lubricant, such as WD-40, when working with stainless steel bolts to prevent thread galling or seizing.
Find Lag Screws for Wood-to-Wood Projects and More
Lag screws are ideally suited for supporting heavy loads both indoors and out. They connect easily and hold firmly for wood-to-wood tasks, like installing deck railings. They can also be used in wood-to-concrete installations on patios or even for mounting heavy objects, such as shelving, onto walls.
Their hex head allows for a secure grip when tightening, ensuring a secure hold even when strained under heavy load.
Lag Bolt Building Applications
- Outdoor Structures: Secure pergolas, gazebos, and playsets where strength and weather resistance are critical.
- Deck Framing: Anchor ledger boards, railing posts, and joist connections for stable, code-compliant decks.
- Fencing & Gates: Provide heavy-duty fastening for posts, hinges, and gate frames.
- Marine Applications: Stainless lag screws are ideal for docks, bulkheads, and boardwalks exposed to saltwater.
