The structure of the flange nut is that there is a wide flange at one end,
which is equivalent to an integrated washer. This structure can
distribute the pressure of the nut to the fixed parts, thus reducing
the possibility of damage to the parts, and it is not easy to loosen
because the fastening surface is not uniform.
Some flange nuts are serrated, which provides any kind of locking action
and acts as an anti-loose lock. The serration of the toothed
flange nut has a special Angle, which can make the nut
rotate in the direction of the principle, so as to achieve
the locking effect, and this serration can not be used with the washer,
nor can it be used for scratched surfaces.
The detachable connection structure is often used between the cylinder
and the head, the pipe fitting and the valve of the pressure vessel to
facilitate the needs of the production process and the convenience of
manufacturing, transportation, installation and maintenance. Common
flange connection, threaded connection and socket connection. The flange
connection has the advantages of reliable sealing, sufficient strength and
wide application range.
Because the fasteners with black zinc plating have good corrosion resistance and wear resistance, they are suitable for harsh working environments, such as Marine environments and chemical equipment. In addition, black zinc plated fasteners are also commonly used in occasions requiring higher aesthetics, such as automotive, electronics and other industries.
Flange screw is a kind of fastener mainly composed of a hexagonal head and two parts of a flange and a screw, which needs to be
matched with the nut for fastening and connecting two parts with a through hole. Flange bolt is a common fastener, because it has the characteristics of accurate decoration and strong endurance, it is widely used in road and railway Bridges, including industrial and civil construction, cranes and other heavy machinery, the scope of application is very wide.
Bentley has invested a huge amount of money to build a product testing laboratory, equipped with imported high-end instruments: such as thread comprehensive scanners, high temperature tensile testing machines, high frequency fatigue testing machines, etc., to ensure that all products are strictly tested before leaving the warehouse to ensure the reliability of customers during use.
