Din6921 Hex Flange Head Bolt Carbon Steel Black Oxide Hex Bolt

Din6921 Hex Flange Head Bolt Carbon Steel Black Oxide

DIN 6921 Hex Flange Bolts are a superior high-performance fastening solution designed to combine the functions of a hex bolt and a washer into a single, robust component. Manufactured from high-grade carbon steel and finished with a durable black oxide coating, these bolts offer exceptional strength, corrosion resistance, and a clean, integrated appearance.

Ideal for automotive, machinery, and structural applications, they streamline assembly, reduce parts inventory, and provide a reliable, vibration-resistant hold.

Key Features & Benefits

Integrated Flange Design: The built-in circular flange beneath the hex head distributes clamping pressure over a wider surface area than a standard hex head bolt. This eliminates the need for a separate washer, prevents loosening from vibration, and protects soft surfaces from damage.
Durable Black Oxide Finish: The black oxide surface treatment provides a sleek, matte-black appearance and offers good corrosion resistance. This finish also reduces light reflection and minimizes galling during installation.
Vibration Resistance: The wide bearing surface of the flange helps maintain clamp load under high-vibration conditions, enhancing the integrity of the assembly.
