The standard DIN 6923, which is also known as ISO 4162, specifies the requirements for hexagon nuts with flange. These nuts are designed to be used in conjunction with bolts and screws to securely fasten components together. The flange on the nut provides a larger surface area for the tool to grip onto, making it easier to tighten or loosen the nut. Additionally, the flange helps distribute the load more evenly, reducing the risk of damage to the connected components. DIN 6923 / ISO 4162 nuts are commonly used in various industries such as automotive, construction, and machinery.
