Carbon Steel DIN 605-1981 120°Flat countersunk head square neck bolts with long square
Product details
As a highly specialized and versatile fastener, the 120° countersunk head square neck bolt is widely used in demanding industrial, construction and manufacturing environments.
Functional characteristics
- 120° Conical countersink: This design is designed to allow the bolt head to be fully embedded in the preset groove, to achieve the effect of flush with the surface, especially for the appearance of high requirements. In addition, the 120° Angle optimizes the pressure distribution, reduces stress concentration points, and improves the reliability of the connection site.
- Square neck: Compared with traditional cylindrical bolts, the square neck can better prevent the bolt from rotating under the action of rotating force, significantly improving the safety of fastening. This design is particularly beneficial for operations in confined Spaces, ensuring bolt stability and maneuverability even in hard-to-reach locations.
- A variety of materials and coatings: 120° countersunk head square neck bolts are usually made of high-strength steel, and can be selected according to specific needs, such as galvanized, nickel plated or stainless steel coating treatment, enhance corrosion resistance, extend the service life.
Application
- High-end manufacturing: In precision instruments, machinery and automated production lines, 120° countersunk head square neck bolts are highly regarded for their seamless assembly and high torque bearing capacity.
- Architectural design: Whether it is metal architecture, curtain wall systems or bridge construction, these bolts provide a strong and hidden means of connection that balances structural stability and visual beauty.
- Automotive industry: From the fixing of body panels to the assembly of engine internal parts, 120° countersunk head square neck bolts are the first choice of manufacturers for their excellent vibration resistance and sealing properties.
- Aerospace: The sophisticated design and high performance of this type of bolt is proven on spacecraft and components that seek extreme lightweight and reliability.
