M6 Hexagon Serrated Flange Nuts Grade 8 Dacromet DIN 6923

Flange nuts are used to fasten components by combining a nut and an integrated washer, which helps to distribute the load, prevent damage to the material, and increase stability. They are used in applications like machinery assembly, plumbing, and construction where a washer is needed but a combined nut and washer is more efficient. They can also be used with oversized or irregular holes, as the flange provides a larger surface area.
