Product Details
The unique head styling not only gives fantastic good looks but also provides a functional element as the washer base spreads the load.These are also machined with rolled threads to give extra strength and a smoother finish.Flange bolts virtually eliminate the need for washers because the area under the bolt head is wider and creates a larger area for even distribution of pressure
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.

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.
