- Always use the correct type and quantity of fasteners as specified by Simpson Strong-Tie for optimal performance and safety. Refer to the product's technical documentation for fastener schedules.
6. Maintenance
- The LSCSS connector is made from 18-gauge stainless steel, offering excellent corrosion resistance.
- Periodically inspect connections for any signs of loosening or damage. Tighten or replace fasteners as necessary.
- Clean the connectors as needed to remove dirt or debris, which can accumulate and potentially affect performance over time.
7. Troubleshooting
Loose Connection:
If the connection feels loose, verify that all fasteners are properly installed and tightened. Ensure the correct number and type of fasteners were used according to the manufacturer's specifications.
Incorrect Angle:
If the stringer angle is incorrect, temporarily remove the stringer, readjust the LSCSS connector to the desired angle, and re-fasten securely.
Corrosion:
While stainless steel is highly corrosion-resistant, prolonged exposure to harsh chemicals or environments can cause surface discoloration. Clean with appropriate stainless steel cleaners if necessary. Avoid abrasive materials that could scratch the surface.
