Distinguish the authenticity of Hettich hinges:

1. Treatment of the U-shaped nails connecting the hinge cup and hinge arm: The U-shaped nails of the authentic Hettich hinges are crushed , to prevent the hinge cup and hinge arm from accidentally falling off. Counterfeit products do not have this treatment.

2. Hinge cup fixed points: Genuine Hettich hinges have granular fixed points at the hinge cup fixing points, while counterfeit products have smooth hinge cup fixing points.

3. Hettich slashes: The four slashes on the hinge arms of genuine Hettich hinges have been canceled in currently produced products, while counterfeit products have four slashes.

4. Brightness comparison: Genuine Hettich hinges are matte and have a soft luster, while counterfeit products are very bright.

5. Scratch resistance: Genuine Hettich hinges are highly scratch-resistant, while counterfeit products can easily scratch with your fingernails.

6. Hettich English trademark: The authentic Hettich hinge cup has a clear Hettich logo inside, while the logo on counterfeit products is blurry.

7. Weight: Genuine Hettich hinges feel heavy, while counterfeit products feel light.

Since the four slashes on the hinge arm of the genuine Hettich hinge have been eliminated in the currently produced products, the counterfeit products have four slashes on the hinge arm. If the hinges installed in 2008 have Hettich slashes on the hinge arms, you can ask the installer to replace them with genuine Hettich hinges.
