Coach screws, also known as lag screws, are a type of large, heavy-duty fastener commonly used in construction and woodworking projects. These screws are designed for attaching heavy objects to wood, such as decks, fences, and sheds, and are known for their strength and durability.

The design of coach screws is what sets them apart from traditional screws. They have a square or hexagonal head, which provides a larger surface area for a wrench or socket to grip, making it easier to tighten and loosen them. The shank of the screw is also typically longer and thicker than traditional screws, which allows for a deeper bite into the wood and more holding power.

One of the key benefits of coach screws is their ability to hold heavy loads. They can be used to secure large, heavy objects such as decks and fences, and can even be used to hold up structural beams in construction projects. They are also commonly used in marine and outdoor applications, as they are resistant to rust and corrosion.

Another benefit of coach screws is their ease of use. Unlike traditional screws, which can be difficult to insert and remove, coach screws can be quickly and easily tightened or loosened using a wrench or socket. This makes them a popular choice for DIY and professional projects alike.

Despite their strength and durability, coach screws do have some limitations. They are not recommended for use in soft or brittle materials, such as drywall or plastic, as they can easily crack or break. They are also not recommended for use in projects that require frequent adjustments or removals, as their large size and deep threads can make them difficult to remove.

Overall, coach screws are a versatile and reliable choice for heavy-duty construction and woodworking projects. Available in Zinc Coated Carbon Steel, A2 Stainless Steel and A4 Stainless Steel for marine applications. Their strength, durability, and ease of use make them a popular choice among professionals and DIY enthusiasts alike. If you are working on a project that requires a strong, durable fastener, coach screws may be the perfect choice for you.
