Coach Screws

They are a very useful multi purpose fix-all fastener and are suitable for use in all general construction and engineering applications offering a flexible solution for heavy duty fixing of general wood constructions, framing timber and man made sheet materials such as plywood and MDF along with masonry and soft substrate fixing such as hollow brick and Hebel when used with a suitable nylon wall plug. Other typical applications include fastening of structural steel brackets and components to timber and stitching timber joists and landscape sleepers together.

These heavy duty screw fasteners are also known as lag screws or lag bolts but should not be confused with coach bolts or carriage bolts which are a bolting product with a nut.
