A2-70,A4-80 Stainless Steel Hex Flange Bolt DIN6921 (SS304 SS316
Flange bolts are hexagonal flange bolts consisting of a hexagonal
head and a flange. The cylindrical externally threaded screw
consists of two parts of various bolts, which are fixed with nuts
for fastening and connecting the two bolt through hole parts.
1, flange categories: Depending on the position of the flange bolts
is different disk size requirements vary, and another flat and
toothed points, toothed anti-slip effect.
2, connected by force, there are common and have articulation hole
of the flange bolts articulation hole to hole size and fit that is
used when lateral force.
3. hexagonal head types: flat brain, the brain and the other is
4.the surface color categories: according to different needs, the
surface coating of white, green, yellow color, corrosion-resistant
In addition, to meet the needs of the lock after installation, the
rod portion with a hole, the holes can not screw loose when subject
Some flange bolts threaded rod portion not to do, called thin rod
flange bolts. This flange bolts in favor of change by force

Ordinary bolt heads are very thick and difficult to deform. If
vibration occurs after the good, it needs to be re-tightened. The
thin part of the flange can be slightly deformed and can be locked
more firmly. Also, if you go up to the hole, there is no way to use
the tool for the ordinary bolt. The flange bolt has a smaller head,
and the lower flange also plays a fastening role, but can be used
to go to the hole with a special tool. , about the same principle
as the hexagon socket bolt. Then there is the flat top pad for the
flange, which is safer on softer, non-wearable materials and does
not cause perforation.
1. A flange is a connection between two large diameter pipes,
usually two flanges plus a number of fastening bolts. Carbon steel
flanges are flanges made of carbon steel. Low-carbon steel has good
plasticity and low strength. When a proper amount of carbon is
added, it becomes hard and the plasticity is reduced.
2. Flange connections may have to withstand high tensile,
compressive, torsional, and shear strength. Carbon steel flanges
are a good choice. The nominal pressure is determined not only
according to the highest working pressure, but also according to
the highest working temperature and material characteristics, not
just the nominal pressure greater than the working pressure.
