A coach screw and various screw plugs are hardware components used for attaching heavy-duty items, such as timber beams, to masonry walls and concrete surfaces.

Coach screws are large, heavy-duty screws with a square or hexagonal head that is typically made of steel or other strong metal alloys. The screw has a sharp point, which allows it to be driven into the masonry or concrete without pre-drilling a pilot hole.

A plug, also known as a wall plug screw, is a cylindrical insert made of plastic or nylon that is designed to fit into the hole created by the coach screw. The plug provides a secure, stable anchor for the screw, and helps distribute the load of the attached item evenly across the wall.

Wall plugs and coach screws are often used for attaching heavy items, such as timber beams, to masonry walls and concrete surfaces, as well as for securing heavy-duty brackets and fittings. To use a coach screws, you simply need to drill a pilot hole in the masonry or concrete, insert the screw plug, and then drive the coach screw into the plug until it is securely in place.

It’s important to follow the manufacturer’s instructions when using coach screws, and to use proper safety gear, such as gloves and eye protection, to protect against injury.
