JX3207 Non-standard customized cup head bolt
The cup head of the bolt provides a better bearing surface, enabling the bolt to distribute pressure more evenly when tightened. Customization may be required for special application scenarios, such as in precision instruments where high precision is needed, or in the aerospace field where extreme environments demand specific properties. It can also be for aesthetic design needs, for example, in high-end furniture or decorative equipment to match the surrounding environment.
