DIN 6928 Stainless Steel Hexagon Flange Head Tapping Screws Self
Tapping Metal Screws
Hex Flange Screws (also called Flange Bolts) incorporate a large
bearing face (flange) into a one piece head design. The large
bearing area under the head of this design provides additional
benefits for assemblies over standard hex head cap screws:
Large bearing area under the head distributes clamp load over a
larger area to resist fatigue loads. Minimizes indentation of the
head into the material being bolted together to prevent loosening.
Increases the heads resistance to rotation to prevent loosening in
high vibration applications. Eliminates the need for a flat washer.
Hex Flange Screws are commonly called Frame Bolts because of their
popularity in the trucking industry for use on assembly of truck
frame rails. Hex Flange Screws are also used on pipe flange
applications because the larger bearing area under the head helps
ensure that the gasket is uniformly compressed to eliminate leaks.
Hex Flange Screw can be used in any assembly that is currently
using a hex cap screw and washer to eliminate the washer.
Earnest Machine Products line of Hex Flange Screws are made to the
dimensions specified in the Industrial Fasteners Institute standard
IFI -111. The head is manufactured with a full trimmed hex to
prevent wrench slipping and rounding of the hex during installation
or removal. The bearing faces are smooth to ensure uniform torque
tension performance and that maximum clamp loads are achieved.
Self-tapping screws in pre-drilled holes in the metallic or
non-metallic material with one kind of self-tapping drilled the
female thread of the threaded fastener. Self-tapping screws are
used for connecting thin metal plate (steel, saws, etc.) between.
When connected to the first connector member is made out of a tap
drill hole, and then self-tapping screws into the threaded bottom
outlet is connected member. Since the self-tapping screw thread
surface with high hardness (≥45HRC), you can attack a threaded
bottom outlet is connected to the internally threaded member,
thereby forming a connection.
|Item Weight||it depends on length|
Flat welding flange: Multi-media for under relatively mild
conditions of the case, such as low-voltage non-purify compressed
air, low pressure circulating water, it has the advantage of
Welded flange: The most commonly used, it is welded tubes, welded
joint quality is better, and the use of taper neck flange
transition, can withstand relatively harsh conditions;
Socket welding flange: commonly used in PN≤10.0MPa, DN≤40 pipeline;
Loose flange: commonly used in the medium temperature and pressure
are not high and medium corrosive conditions. When the corrosive
medium, contacting the media portion of the flange (flange short
section) corrosion-resistant high-grade materials such as stainless
steel and other materials, and the use of external low-grade
materials such as carbon steel flange ring clamp it in order to
effect a seal;
Earnest Machine Products line of Metric Hex Flange Bolts are made
to the dimensional tolerances specified by DIN 6921.
