Round head square neck carriage bolt 8.8 grade galvanized carriage bridge screw
The carriage bolt is a type of fastener characterized by a smooth, rounded head and a square neck beneath the head that prevents rotation during installation. Commonly used in wooden structures, furniture, and metal connections, carriage bolts provide strong, secure joints. They are typically designed to be driven into pre-drilled holes and are available in various lengths, diameters, and materials, including steel and stainless steel, to suit different applications. Their durability and ease of installation make them a popular choice in construction and woodworking projects.
structural design
The structural design of a carriage bolt involves several key elements. Typically, it features a smooth, rounded head and a long, cylindrical shank with a square section just beneath the head to prevent rotation during installation. The threaded portion allows for secure fastening with a nut or directly into a pre-drilled hole. Material selection is crucial, often utilizing high-strength steel for durability. The design must also consider load-bearing capacity, environmental factors, and corrosion resistance, ensuring that the carriage bolt performs effectively in various applications, such as in woodworking or metalworking projects.
