What is lag screw?

A lag screw is a type of screw that is used to fasten heavy objects to wood. It is a thick, coarse-threaded screw that has a large head and a sharp point. Lag screws are typically made of steel or galvanized steel, and they come in a variety of sizes.

Lag screws are used in a variety of applications, including:

* Fastening joists to beams

* Attaching decking to joists

* Securing cabinets to walls

* Hanging heavy fixtures

* Installing storm shutters

Lag screws are installed by drilling a pilot hole into the wood, and then inserting the screw. The pilot hole should be slightly smaller than the diameter of the screw shank. The screw should be driven in until the head is flush with the surface of the wood.

Lag screws provide a strong and secure hold, and they are resistant to pulling out. They are also easy to install, making them a popular choice for a variety of applications.

Here are some tips for installing lag screws:

* Use a sharp drill bit to drill the pilot hole. A dull drill bit can cause the wood to split.

* Drive the screw in slowly. This will help to prevent the wood from splitting.

* Use a washer under the head of the screw. This will help to distribute the load and prevent the wood from sinking around the screw.

* Lag screws are a versatile and strong fastener that can be used in a variety of applications. By following these tips, you can ensure that your lag screws are installed correctly and securely.
