What is a lag bolt?

A lag bolt, also known as a lag screw, is a type of fastener that features a hexagonal or square head and a sharp, pointed tip. It is typically used to fasten heavy materials or structural components together, such as fastening wood to wood or wood to metal.

Lag bolts are often used in construction and woodworking projects where high strength and durability are required. They are available in a variety of sizes and lengths to accommodate different applications. The length of a lag bolt is typically measured from the top of the head to the tip of the screw.

To install a lag bolt, a pilot hole must be drilled slightly smaller than the diameter of the bolt. This helps prevent splitting of the wood and ensures a secure and tight fit. A wrench or socket wrench is typically used to tighten the bolt into place.

Overall, lag bolts are a versatile and reliable fastening solution for heavy-duty applications that require a strong and secure connection.
