Product description
Black Zinc-Plated Serrated Hex Flange Bolt
- Serrated Locking Flange: The underside of the wide flange features integrated anti-vibration serrations that grip mating surfaces, eliminating the need for separate lock washers and effectively resisting vibrational loosening.

- Durable Black Finish: Coated with a premium black zinc or black oxide surface treatment that enhances corrosion resistance while offering a sleek, professional matte-black appearance.
- Integrated Washer Base: The expansive built-in flange evenly distributes clamping force over a broader surface area, reducing contact pressure and preventing damage to delicate joint materials.
- High Tensile Material: Precision forged from high-strength carbon or alloy steel to deliver reliable load-bearing capacity, fatigue resistance, and robust clamping performance.
- Wide Applications: Ideal for automotive chassis components, exhaust systems, machinery frames, structural steel assemblies, solar mounting hardware, and industrial equipment subjected to high dynamic stress.
