What is a Lag Bolt?

A lag bolt, also known as a lag screw, is a large, heavy-duty fastener with a hexagonal head and coarse threads designed for creating strong connections in wood or other soft materials. Unlike regular screws, lag bolts require a pre-drilled pilot hole and are tightened using a wrench or socket. They are commonly made from materials like stainless steel, galvanized steel, or carbon steel to ensure strength and corrosion resistance.

Key Features of a Lag Bolt:

• Hexagonal Head: Allows for easy tightening using a wrench or socket.
• Coarse Threads: Provides a secure grip in wood or other soft materials.
• High Strength: Capable of withstanding heavy loads and structural stress.
• Durable Material Options: Available in stainless steel, galvanized, or coated finishes for rust resistance.
• Variety of Sizes: Offered in multiple lengths and diameters to suit different applications.

Common Uses:

• Securing heavy wood-to-wood or wood-to-metal connections in construction.
• Attaching beams, posts, or frames in building structures.
• Fixing heavy-duty equipment or machinery to wooden bases.
• Outdoor projects like decks, fences, and retaining walls.
• Applications requiring long-lasting and robust fastening solutions.
