Lag screw sizes are important to know when you’re working on construction projects. These are large fasteners that can support a lot of weight and are used to connect wood applications with each other. While they may be a bit more expensive than other types of wood screws, lag bolts will provide you with the strength and security you need to ensure your project is built correctly.

These bolts have a wide range of uses and are commonly used to lag lumber framing together, lag machinery feet to the floor and for other heavy carpentry applications. They are available in a variety of diameters and lengths. Lag bolts are also manufactured in stainless steel and other alloy metals for increased strength and corrosion resistance.

Most lag screws have a hex head and have pointed wood threads. The hex head makes them easy to install by hand and they can be tightened using a hex wrench. They are also sometimes known as hex wood screws, hex lags or wood lag bolts. They can also be purchased with a square or round head, but most tradesmen use the hex headed varieties.

When it comes to choosing a lag bolt, the two most important dimensions are the head diameter and length. The diameter determines how far the bolt will penetrate into a wooden stud and the length determines how much the bolt will thread into a hole. Lag bolts must have a pilot hole drilled for them before they can be installed and this is an important step to prevent the lag bolt from splitting or damaging the wood stud. Lag screw sizes
