Product Information Coach Screws are heavy-duty, large-threaded fasteners designed for securing wood to wood or metal to wood, providing a strong and reliable connection. Featuring a hexagonal or square head, coach screws allow for easy installation using a wrench or socket, ensuring a secure, tight fit. Made from durable materials such as steel, stainless steel, or galvanized steel, they are corrosion-resistant and ideal for outdoor and structural applications. Commonly used in decking, fencing, and heavy timber construction, coach screws offer exceptional holding power, making them perfect for projects requiring long-lasting strength and durability.
