Product Details
The DIN Hex Flange Bolt is a high-strength fastening component designed for applications requiring secure and stable connections. Adhering to German Industrial Standards (DIN), these bolts are recognized for their precision and reliability.
We also supply hex flange nuts that work in tandem with our hex flange bolts. We have different grades of hex flange bolts, hex flange nuts, and hex flange screws to fit a wide range of applications. Stainless steel is widely used in the fastener industry,which not only looks great but has other benefits too..

Material: Manufactured from premium quality carbon steel or alloy steel, providing the necessary tensile strength and durability.
Flange Design: Features a flange under the head that distributes the load evenly, preventing the bolt from sinking into soft materials.
Hex Head: The hexagonal head allows for use with standard hex keys and wrenches, ensuring ease of installation.
Thread Type: Available in both coarse and fine threads to suit various applications and materials.
Corrosion Resistance: Depending on the finish, these bolts can be treated to resist corrosion, suitable for both indoor and outdoor use
Suitable for heavy-duty construction projects, including building structures, bridges, and heavy machinery.
Ideal for automotive and aerospace industries where high-strength fasteners are critical.
Can be used in mechanical engineering for securing components that require strong and durable fastenings.
