Screws and bolts are fundamental components in construction and manufacturing, serving as essential fastening eLEMents to join multiple parts securely. Screws are typically characterized by their helical ridge, known as a male thread, and are designed to be fastened into a tapped hole or driven into materials such as wood, metal, or plastic. They are widely used for precision and strength in fastening, providing the necessary grip and ease of installation and removal. Bolts, on the other hand, are larger fasteners with a head and a cylindrical body with a helical thread, and they require a nut to secure them in place. They are mainly used in applications where a strong, more permanent hold is necessary, and they can be found in everything from furniture assembly to infrastructure projects.
The main uses and characteristics of screws and bolts lie in their versatility and strength. Screws offer a reliable grip in a variety of materials and are often used in applications where parts may need to be disassembled for maintenance or adjustment. They come in a vast array of head styles, materials, and sizes to suit different requirements. Bolts, due to their robust nature, are used to provide a strong and secure joint in heavy-duty applications, ranging from automotive to structural engineering. They are particularly valued for their ability to withstand high levels of stress and tension. Some of the notable manufacturers of screws and bolts include Acme Manufacturing, Precision Bolts Co., and Global Fasteners Inc.
