4. Setup & Installation
These cross nuts are designed for use with standard M6 bolts (sold separately). Proper installation ensures the stability and durability of your assembly.
Installation Guidelines:
- Select Correct Size: Choose the appropriate nut length based on the thickness of the material you are joining.
- Prepare Hole: Drill a pilot hole in your material (e.g., wood, plywood) that matches the diameter of the cross nut (10mm). Ensure the hole is clean and free of debris.
- Insert Nut: Carefully insert the cross nut into the prepared hole. The rounded edges are designed to minimize damage to the wood surface.
- Secure with Bolt: Align an M6 bolt with the internal thread of the cross nut. For optimal performance, use a low torque impact driver to secure the bolt. Avoid overtightening to prevent damage to the nut or material.
- Check Stability: After installation, ensure the assembly is stable and the nut is firmly seated.

6. Maintenance
To ensure the longevity and optimal performance of your Gorise M6 Carbon Steel Cross Nuts, follow these simple maintenance guidelines:
- Storage: Store unused nuts in a dry place to maintain the integrity of the zinc coating and prevent corrosion. The provided compact storage box is ideal for this purpose.
- Inspection: Periodically inspect assembled joints for any signs of loosening. Tighten M6 bolts as necessary, ensuring not to overtighten.
- Cleaning: If exposed to dirt or grime, gently wipe the nuts with a dry cloth. Avoid harsh chemicals that could damage the coating.
7. Troubleshooting
If you encounter issues during installation or use, consider the following:
- Nut Not Fitting: Ensure the pilot hole diameter is 10mm. Check for any obstructions in the hole.
- Bolt Not Engaging: Verify that you are using a standard M6 bolt. Ensure the bolt is aligned correctly with the nut's internal thread.
- Loose Connection: Confirm that the correct length of cross nut was chosen for the material thickness. Tighten the M6 bolt appropriately, but avoid excessive force.
- Corrosion: If nuts show signs of corrosion, ensure they are stored in a dry environment. The zinc coating provides resistance, but prolonged exposure to moisture can still cause issues.
