Installation and care tips

To install, use an appropriately sized hex key or Allen driver to achieve a secure fit without over-tightening. Ensure threads engage cleanly—clean any debris from the tapping holes or brackets before installation. If the screws will be exposed to moisture or outdoor conditions, periodic inspection and light cleaning will help maintain corrosion resistance. Store the kit in a dry, organized container to preserve thread quality and ease of access for future maintenance tasks.
