DIN 6928 Stainless Steel Hexagon Flange Head Self Tapping Screws / M10 Flange Bolts

DIN 6928 Stainless Steel Hexagon Flange Head Tapping Screws Self Tapping Metal Screws

1.Product Description

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.

3.Application

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 cheaper prices;
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;

4.Advantages

Earnest Machine Products line of Metric Hex Flange Bolts are made to the dimensional tolerances specified by DIN 6921.
