Flange bolts are a common fastener, flange bolts are widely used in road
and railway Bridges, including industrial and civil construction,
cranes, excavators and other heavy machinery, the
scope of application is very wide.
Hexagonal flange type: There are two kinds of hexagonal head, one is flat
brain, the other is concave brain. Surface color category:
According to different needs, the surface has
plated white, military green, color yellow, another never rust
Dacromet. Flange type: According to the use of flange screws in different
places, the size of the disk requirements are different, and there
are flat bottom and teeth, teeth play a non-slip role.A
Bentley has industry-leading stainless steel resource
integration capabilities, and rich raw material reserves,
to ensure that thousands of leading position in the
stainless steel wire processing industry. The
combination of production, university and research,
upstream and downstream linkage, and the special
research and development of high-standard specific
materials ensure the need for thousands of professional
materials.
Scope of
application
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.
Quality
Certification
According to the force mode of the connection, there are ordinaryand hinged holes. The flange screws used for reaming holes should
match the size of the holes and be used when subjected to transverse forces. In addition, in order to meet the needs of locking after installation, there are holes in the rod part, which can make the bolt not loose when it is subjected to vibration.
inspection
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.
