Carbon Steel DIN 6921-1983 Hexagon flange bolts with grooved design (HO)
Product Overview:
The hexagonal head flange bolt (groove design) is a fastening element with a unique groove design. The hexagonal head is easy to tighten with tools such as wrenches, while the flange part increases the contact area and improves the stability and carrying capacity of the connection. The groove design further enhances the holding force between the bolt and the nut or the connector, reduces the risk of loosening, and is suitable for heavy machinery, building structures, automotive industry and other fields, and is an important part to ensure engineering safety and equipment stability.

Carbon Steel DIN 6921-1983 Hexagon flange bolts with grooved design (HO) Details
Hexagon flange bolt is a fastener product with special groove design. The bolts thread specification range from M5 to M20, with a pitch varying from 0.8mm to 2.5mm. The product grade is Grade A. The material is carbon steel, which has many grades to choose. According to customer needs, surface treatments such as blackening (heating or chemical), electric galvanizing, hot dipping zinc can be carried out to improve the corrosion resistance and aesthetics of bolts.Product tolerances and accuracy meet the relevant requirements of DIN standards to ensure the stability and reliability of product quality.
Product Characteristics
Application
Because of its unique groove design, the product is widely used in mechanical connections requiring higher fastening performance and anti-loosening requirements, such as automotive, aerospace, heavy machinery and other fields.
Product Characteristics
- Groove design: Groove is usually designed on the head or flange face of the bolt, the specific position depends on the design requirements. The groove design can be used with locking washers, locking pieces and other anti-loosening elements to effectively prevent bolts from loosening in vibration or impact environments by increasing friction or mechanical locking.
- Flange: located below the head, increases the contact area with the connector, enhances the fastening stability and anti-loosening performance. Flanges can be divided into two kinds according to demand, flat bottom and tooth, tooth flanges have better anti-slip effect.
- Excellent anti-loosening performance: The design of the flange allows the bolt to be more firmly locked on the connector after tightening, reducing loosening due to vibration or impact.
- Wide applicability: Hexagonal flange bolts are suitable for a variety of assembly scenarios, including road and railway Bridges, industrial and civil construction, heavy machinery and other fields.
Application
Because of its unique groove design, the product is widely used in mechanical connections requiring higher fastening performance and anti-loosening requirements, such as automotive, aerospace, heavy machinery and other fields.
- Aerospace: hexagonal flange bolts are also widely used in the connection of structural components of aircraft and rockets.
- Heavy machinery: In cranes, excavators, mining machinery and other equipment, hexagonal flange bolts with its strong tensile and shear performance, as well as the additional support area provided by the flange design, can effectively disperse stress, reduce fatigue damage at the joint, and ensure the stable operation of equipment under harsh conditions.
- Automotive industry: Used to fix engines, chassis and body parts, its high strength and corrosion resistance meet the stringent requirements of automotive parts. These bolts ensure the safety and reliability of the vehicle under various working conditions.
