Nonferrous EN 14399-10-2018 Twist-off type tension control structural bolts with heavy hex head
Product details
Twist-off type tension control structural bolts with heavy hex head specifications range from M12 to M30, with a pitch varying from 1.75mm to 3.5mm. Typically made of alloy steel, its unique torque-shear design ensures that the connection pair can achieve the predetermined preload during tightening, thereby improving the stability and safety of the connection. The bolts made of non-ferrous metals such as copper and aluminum are often used in occasions with high requirements for strength and corrosion resistance.
Product Characteristics
- High strength: The use of high-quality materials, after special processing, to ensure that the bolt has a very high tensile strength and yield strength, to meet the safety requirements of high load working environment.
- Torsional shear design: The unique torsional shear design makes the bolt automatically break when it reaches the predetermined preload, so as to accurately control the preload and avoid the occurrence of too tight or too loose.
- Hexagonal head: The hexagonal head design is easy to tighten with tools such as wrenches or torque wrenches to improve installation efficiency.
- Precise control: By controlling the breaking torque of the bolt, the precise control of the preload force is achieved to ensure the stability and safety of the connection structure.
ApplicationWidely used in bridges, construction, machinery, transportation and other fields, especially in the need of high-strength connection and accurate preload control, such as steel structure connection, large equipment assembly.
- Construction: Used in buildings to join and fix components.
- Mechanical: Used in mechanical equipment to connect and fix key components to ensure the stable operation of the equipment.
- Transportation: Used in railway, road and other transportation facilities to connect and tighten tracks, Bridges and other structures.
