Top 10 Metric Flange Nuts Suppliers in the world 2026

Introduction to Metric Flange Nuts

Metric flange nuts are a type of fastener widely used in various industries. They are characterized by a wide flange at one end, which acts as an integrated washer. This flange distributes the load over a larger area, reducing the risk of damage to the surface being fastened and providing a more secure connection compared to standard nuts. Metric flange nuts follow the metric measurement system, which is widely adopted globally, ensuring compatibility with metric bolts and screws. They are commonly made of materials such as steel, stainless steel, brass, and aluminum, offering different levels of strength, corrosion resistance, and durability to meet a variety of application requirements. These nuts are used in automotive, machinery, construction, and many other fields where reliable fastening is essential.
