The ART 88913 flange bolt with serrated flange is called a self-tightening bolt because it is able to increase the adhesion force to the substrate, thereby preventing the fastener from loosening. In addition, the press washer protects the seat from damage by increasing the bearing area. The majority of the ART 88913 range of bolts belongs to the high-strength fastener class. This is due both to the types of materials used in production and to their design. This bolt has a cylindrical base with a full/incomplete metric thread and a hexagonal head with a flange in the form of a press washer. The flange can be flat, as well as have a grooved lower surface of the head or locking teeth.
Strength class ART 88913
The strength class of a bolt is the maximum applied force at which the bolt begins to fracture. The flange bolt ART 88913 is only available in high-strength steel with strength classes 8.8 and 10.9.
Fastening group ART 88913
Depending on the material of manufacture, the ART 88913 is divided into different fastening groups:
- High-strength fasteners - fasteners made of steel with a strength class of 8.8 or higher.
- Stainless fasteners - fasteners made of stainless steel.
Materials of manufacture ART 88913
The ART 88913 flange bolt is available in the following materials:
- Steel, which can optionally be coated with hot-dip galvanized, ordinary galvanized, yellow galvanized and plate galvanized zinc
- Stainless steel (A2, A4) does not need to be coated
Where are the ART 88913 flange/toothed flange bolts used?
The ART 88913 bolt is used in wet and outdoor environments, structures in solar installations. In addition, the application area directly depends on the material of manufacture and the coating of the product:
- Galvanized steel is a good protection against corrosion if the fastener is to be used in an aggressive environment.
- Stainless steel allows the fasteners to be used at significant temperature changes and in aggressive and humid environments.
