What Is a Lag Bolt?
A lag bolt (also known as a lag screw) is a fastener that looks like a very large wood screw with a hexagonal head and thick threads. It’s an extremely versatile and strong fastener that can be used in a wide range of projects and can hold much more weight than other types of screws. Lag bolts are made in a variety of sizes and lengths, so it’s important to choose the right one for your project.
When using a lag bolt, it is important to make sure that you have the correct tools and knowledge before starting your project. You’ll need a tape measure and clamps to help you get the job done correctly. You’ll also need a drill that can fit the size of the bolt, as well as a wrench or ratchet. Finally, you’ll need a drill bit that fits the head of the bolt, and you’ll want to use a high-torque power tool when driving it.
When using a lag bolt, it’s important to remember that the threads can damage the surface of the wood it’s attached to if tightened too hard. This is why it’s important to use a wrench or ratchet when tightening the bolt, as opposed to a screwdriver, which could cause it to overheat and damage the bolt head. It’s also important to follow construction drawings when laying out the location of the bolts. They usually recommend a minimum edge distance of 1.5 times the bolt diameter and a maximum end distance of 2 to 3.5 times the bolt diameter, as per NDS tables 12.5.1A and 12.5.1C. Lag Bolt
