Lag Screw

Lag screws, also known as lag bolts, are a type of screw that is commonly used in construction and woodworking projects. They are part of the supply class Screws in the supply group Hardware And Abrasives.

Lag screws are typically larger and stronger than regular screws, with a thick, coarse thread and a hexagonal head. They are designed to be used with a wrench or socket to provide maximum torque and holding power.

These screws are commonly used for heavy-duty applications where a strong connection is required, such as attaching beams, posts, or brackets to wood or other materials. They are often used in building decks, fences, and other outdoor structures.

Lag screws are available in various lengths, diameters, and materials, including steel and stainless steel. The length and diameter of the lag screw you choose will depend on the specific application and the thickness of the materials you are working with.

When using lag screws, it is important to pre-drill a pilot hole to ensure proper installation and prevent splitting of the wood. The pilot hole should be slightly smaller than the diameter of the screw, allowing for a tight fit.

Overall, lag screws are a reliable and durable option for securing heavy objects and providing strong connections in construction and woodworking projects.
