M10 1050 METAL BOLT Carbon Steel Black Oxide Hex Serrated Flange Bolt With Nut DIN6921

Hexagonal flange nuts mainly consist of a nut body, with a flange fixed at one end and a cap fixed at the other end. The inclusion of the cap ensures excellent sealing performance when using hexagonal flange nuts, effectively preventing harmful substances such as rainwater, moisture, and dust from penetrating the nut body. This helps avoid corrosion of the nut, thereby significantly extending the service life of hexagonal flange nuts.

In the automotive steering system (STEERING SHAFT ASSY), four M10X25 bolts are used to secure the upper and lower shaft assembly. The transmission mounting bracket of the drive system employs M12X70 hexagonal flange bolts. The wiper system is configured with M6X16 hexagonal flange bolts, which, through a U-shaped clamping structure and spring elements, can maintain displacement within 0.01 mm in high-frequency vibration environments. The battery system fixation bolts feature a dual-layer sealing structure and have passed IP67 waterproof certification tests.

• The shank part of the hex flange screws adopts a hexagonal design. This design is not only aesthetically pleasing and elegant but, more importantly, facilitates rotation with a wrench, enabling tightening and loosening operations.
• At the other end of the shank, the hex flange screw is equipped with a flat flange. The function of this flange is to increase the connection area, enhancing the stability and sealing of the joint.
• Compared to ordinary bolts, hex flange screws have a larger ratio of bearing area to stress area, allowing them to withstand higher preload forces and ensuring a more secure connection.
• Thanks to the presence of the flange, hex flange screws can effectively prevent loosening under vibration or impact, ensuring the stability of the connection.
