Lag bolts, also known as lag screws, are heavy-duty fasteners perfect for creating secure connections in wood and other materials. They are designed to provide superior strength and durability, making them ideal for a wide range of applications, perfect for professionals and DIYers alike.

Benefits of Lag Bolts

• Durability: Lag bolts are built to withstand heavy loads and harsh conditions, ensuring long-lasting performance.
• Strength: These bolts provide strong, secure connections, essential for heavy-duty applications.
• Versatility: Suitable for various uses, including structural and non-structural applications.

Types of Lag Bolts Available:

Lag Bolts are available in a wide variety of sizes, materials, and head types - each designed for unique purposes.

Lag Bolt Types:

• Hex Head Lag Bolts Feature a traditional six-sided head, most common type of lag screws and perfect for general construction.
• Square Head Lag Bolts Feature a square head in place of the traditional hex head, they can be used the same way as hex-head lag bolts but may be chosen for aesthetic reasons.
• Flange Head Lag Bolts Feature an integrated washer under the head to distribute the load more evenly without the need for a separate washer.
• Concrete Lag Bolts While lag bolts aren't technically 'concrete lag bolts', they can be combined with a lag shield anchor to be used in concrete or other masonry materials.

Lag Bolt Materials:

• Hot-Dip Galvanized Lag Bolts Provides moderate corrosion resistance, good for many outdoor environments but especially resilient indoors.
• 304 Stainless Steel Lag Bolts Provides heavy corrosion resistance, making them perfect for outdoor environments or closed animal confinements.
• 316 Stainless Steel Lag Bolts Offers maximum corrosion resistance, providing the ideal choice for severe marine environments - especially near salt water, and any other application where corrosion is an issue.

Lag Bolt Sizes:

• Diameter This relates to the thickness of the bolt, and can be found in many different sizes, the larger the diameter generally relates to the higher strength. We offer lag bolts from 1/4" to 3/4" thick.
• Length The length of a lag bolt will differ depending on your particular application, the longer the lag bolt for larger jobs. We offer lag bolts from 1" to 20", with most common sizes between 4" and 6".

Related Products to Lag Bolts:

Lag Bolts can be used in conjunction with other products, depending on the project. Commonly, either washers or a lag shield anchor may be necessary.

• Washers Washers help distribute the load over a larger surface area. This prevents the bolt head from embedding into the material and reduces the risk of damage or splitting, especially in softer woods or materials.
• Lag Shield Anchor Lag shield anchors provide a secure and stable hold for lag bolts in masonry materials like concrete. They expand as the lag bolt is tightened, creating a strong grip within the drilled hole, which prevents the bolt from loosening or pulling out.
• Nuts Not commonly used with lag bolts because the pointed tip is used to fasten directly into a material, hex nuts can still be used with lag bolts if necessary.
