We know that the screw is screwed into the product as a fastening action, the screw head and the surface of the product are acting on each other, fastening the connection between the parts of the product.The smaller the contact area of the screw head and the product, the greater the pressure, the more easily damaged the surface of the product.While this belt screw than ordinary screw head without interface area is much bigger, and product contact area, the greater the more is not easy to damage the surface of the product, which is why will appear this kind of screw with medium.It is different from the screw and the flat cushion, the screw is used to prevent the screw loose.This is designed to protect the product from damage.
Screws and bolts are usually made of steel. Where great resistance to weather or corrosion is required, like in very small screws or medical implants, materials such as stainless steel, brass, titanium, bronze, silicon bronze or monel may be used.
Galvanic corrosion of dissimilar metals can be prevented (using aluminum screws for double-glazing tracks for example) by a careful choice of material. Some types of plastic, such as nylon or polytetrafluoroethylene (PTFE), can be threaded and used for fastenings requiring moderate strength and great resistance to corrosion or for the purpose of electrical insulation.
Often a surface coating is used to protect the fastener from corrosion (e.g. bright zinc plating for steel screws), to impart a decorative finish (e.g. japanning) or otherwise alter the surface properties of the base material.
Selection criteria of the screw materials include: size, required strength, resistance to corrosion, joint material, cost and temperature.
