Hex flange bolts and screws are premium fasteners characterized by their hexagonal heads and an integrated washer-like flange beneath the head, engineered to offer exceptional load distribution and vibration resistance. Designed explicitly for heavy-duty applications, these fasteners ensure secure and reliable fastening solutions, particularly where high tensile strength and vibration mitigation are crucial. Manufactured in diverse material grades such as carbon steel, alloy steel, and stainless steel (including grades 4.6, 8.8, 10.9, 12.9, and stainless steel 304/316), these bolts and screws cater to rigorous industrial demands. The flange's broad surface area helps distribute clamping force evenly, reducing material damage and improving joint integrity. Serrated flange variants provide augmented anti-loosening capabilities, enhancing performance in dynamic environments like automotive engines, transmissions, and structural steel assemblies. Available surface finishes like bright zinc plating, black oxide, hot-dip galvanizing, and stainless steel variants ensure resistance against corrosion and environmental factors. Complying with DIN 6921 and equivalent international standards, these hex flange bolts and screws come in multiple sizes (M5 to M30), tailored to meet precise dimensional and strength requirements. By eliminating the need for separate washers, these integrated fasteners streamline assembly processes, reduce inventory complexity, and deliver durable, versatile fastening solutions across automotive, construction, industrial fabrication, and DIY applications.

The integrated flange acts like a built-in washer, distributing the clamping load over a larger surface area which reduces material damage and increases joint stability, enhancing overall fastening performance.
Serrated hex flange bolts feature serrations on the flange underside that dig into the mating surface, significantly increasing resistance against loosening caused by vibration and dynamic loads.
For corrosive environments, stainless steel grades 304 and 316 are recommended due to their superior corrosion resistance compared to carbon or alloy steels.
Hex flange screws share a similar design but are generally shorter and used in lighter assemblies; while interchangeable in some cases, it is important to verify load requirements and standards compliance before substitution.
Yes, the integrated flange in hex flange bolts acts as a built-in washer, making the use of separate washers unnecessary in most fastening applications.
