1.High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws：Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws are made of high-strength anti-corrosive materials with excellent tensile and shear strength and corrosion resistance, suitable for harsh environments. Easy to install, reusable, solid, and reliable connection, effectively improves productivity and reduces costs, is an indispensable connector in industrial production.

The features of Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws mainly include.

Structural design: the screw part of the bolt adopts a hexagonal design, which is not only aesthetically pleasing but, more importantly, is easy to rotate with a wrench, thus realizing tightening and loosening operations. At the other end of the screw, it is equipped with a flat flange, and the function of this flange is to increase the connection area and improve the solidity and sealing of the connection. 

Performance advantages: Compared with ordinary bolts, Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws have a larger ratio of support area to stress area and can withstand higher preload. This ensures a strong connection. In addition, due to the presence of the flange, this type of bolt can effectively prevent loosening when subjected to vibration or impact, ensuring the stability of the connection. Its installation and dismantling process is straightforward and can be completed using a wrench without additional tools, significantly improving the working efficiency. Hexagonal flange screws are usually made of high-quality materials, such as SCM435 chromium-molybdenum alloy steel, etc., which have high corrosion resistance and are suitable for a variety of harsh environments. 

Application Scenario: Widely used in occasions that require high strength of connection, such as manufacturing and repairing mechanical equipment, supporting and fixing construction projects, and connecting critical components in automobile manufacturing. In these fields, Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws can provide solid support and connection to ensure the safety and stability of equipment and construction. 

In summary, Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws play an essential role in various fields with their unique structural design and excellent performance advantages.

Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws are tightly constructed and can be very easily reinstalled without damaging the bolts or flanges when disassembled. This strong reusability makes flange face bolts the most commonly used connector in industrial production.

Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws have a strong and reliable connection that will not loosen or leak under high pressure. In addition, when critical equipment is connected, flange face bolts can also be designed with double sets and double nuts to avoid accidental dismantling or equipment accidents.

In conclusion, Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws have the advantages of high strength, good corrosion resistance, easy installation, strong reusability, safety, and reliability, etc., which have become indispensable connecting devices in industrial production, and play a vital role in improving production efficiency and reducing costs. It has become an indispensable connecting device in industrial output and is crucial in enhancing production efficiency and reducing costs.
