2.2. Step-by-Step Installation
Follow these steps to securely fasten the backing board to your picture frame:
- Position the Turn Button: Place the turn button fastener on the back plate of the photo frame, ensuring it overlaps both the frame and the backing board. The flat end of the turn button should be positioned over the backing board, and the screw hole should align with the frame's edge.
- Align the Screw: Insert one of the provided black screws through the hole in the turn button fastener.
- Tighten the Screw: Using a screwdriver, carefully tighten the screw into the frame. Ensure the screw is snug but do not overtighten, as this may damage the frame material. The turn button should pivot freely when loosened and hold the backing board firmly when tightened.

3. Care and Maintenance
To ensure the longevity and proper function of your Yuntop turn button fasteners:
- Storage: Store unused fasteners and screws in the provided transparent case in a dry environment to prevent moisture exposure.
- Cleaning: If necessary, wipe the fasteners with a dry cloth. Avoid using harsh chemicals or abrasive materials.
- Rust Prevention: The fasteners are treated with an anti-rust oil. A slight initial odor is normal and will dissipate.

4. Troubleshooting
- Fastener Not Holding Securely: Ensure the screw is fully tightened. Check that the turn button is correctly positioned to overlap both the frame and the backing board.
- Difficulty Turning Fastener: If the fastener is too tight to turn, slightly loosen the screw. Ensure the screw is not overtightened into the frame material.
- Initial Odor: A slight odor may be present upon opening due to the anti-rust oil applied during manufacturing. This is normal and will dissipate over time.
