Coach screws, also known as lag screws, are heavy-duty fasteners designed for securing large, heavy objects to wood or masonry.

They feature a hexagonal head for easy turning with a wrench or socket, and a thick, coarse threaded shank for strong holding power.

Made from high-quality steel and galvanized for corrosion resistance, coach screws are ideal for outdoor applications such as fastening timber beams, posts, and heavy-duty hardware.

To use coach screws, first drill a pilot hole in the wood or masonry to the appropriate size for the screw.

Insert the screw into the pilot hole and use a wrench or socket to turn the hexagonal head, driving the screw into the material.

Coach screws are ideal for heavy-duty woodwork and construction, providing a secure hold for large timber beams, posts, and other substantial structures.

Coach screws can also be used for fastening medium-weight objects to brick walls by pairing them with wall plugs.

To do this, drill a hole in the brick, insert the appropriate-sized wall plug, and then drive the coach screw into the plug using a wrench or socket.

This method provides a secure hold for items such as shelving brackets, outdoor fixtures, and other medium-weight installations on masonry surfaces.
