Nonferrous Metals EN 1665-2008 Hexagon bolts with flange-heavy series-Type U
Product details
Hexagon bolts with flange-heavy series-Type U thread specifications range from M5 to M20, with a varying from 0.8mm to 2.5mm. The material is nonferrous metals. For example, copper bolts can be used for occasions with high corrosion protection and electrical conductivity requirements, and aluminum bolts can be used for lightweight materials and high temperature environments. In order to further improve the corrosion resistance and aesthetics of these bolts, the surface treatment method is blue and white zinc plating.
Product Characteristics
- Structure: The hexagon flange bolt is composed of three parts: a hexagon head, a flange (the gasket below the hexagon and the hexagon are fixed as one part) and a screw (a cylinder with external threads). The head is composed of two parts: the hexagonal head and the flange face, and the flange face has a thin part, which can be slightly deformed and can be locked more firmly.
- Performance advantage: The "support area to stress area word ratio" of flange bolts is greater than that of ordinary hexagonal head bolts, so this bolt can withstand higher preload and anti-loosening performance is also better. Ordinary bolt head is very thick, difficult to deform, if vibration occurs after good, but also need to re-tighten; The head of the flange bolt is small, but it can be used to go to the hole with a special tool, and the principle of the hex bolt is about the same.
ApplicationBecause of its high strength and good anti-loosening performance, it is usually widely used in areas with high requirements for fasteners.
- Automotive manufacturing: Components used to connect and fix key parts of the automobile engine, chassis and so on.
- Heavy machinery: plays a connection and fastening role in heavy machinery and equipment to ensure the stability and safety of the equipment.
- Other fields: It is also used for fastening connections in Bridges, construction, aerospace and other fields, as well as mechanical parts and parts processing in stationery, computers, electrical appliances, home appliances, toys, lighting and other industries.
