M8/20 flange bolt
The M8/20 flange screw is a type of screw that is characterized by the presence of a built-in flange, which often eliminates the need for an additional washer. The size "M8" indicates the screw thread diameter, which is 8 millimeters, while "20" refers to the screw length in millimeters.
Flange bolts are commonly used in a variety of structural and mechanical applications because the flange provides a larger surface area for pressure distribution than standard bolts. This allows them to better maintain the connection, reducing the risk of the screw coming loose due to vibration or load.
The material from which the screw is made and its specific characteristics, such as thread type and strength, will depend on the manufacturer and the intended use of the screw. M8/20 flange bolts are used in many industries, including construction, automotive and engineering.
