Questions & Answers
What about using for 6"x6" timber retaining wall?
Yes, these structural screws are suitable for fastening large timbers like 6x6s, including layering and securing corners or tie-backs in a retaining wall. For best results, pre-drill in dense or dry timbers, and target at least 2–3 inches of embedment into the receiving member. Use 2–3 screws per connection, staggered and set back from edges and ends to minimize splitting, but follow your local code or engineer’s spacing requirements. The exterior coating is designed for pressure-treated lumber; in coastal or highly corrosive environments, confirm compatibility or consider stainless options. Retaining walls over common height thresholds or carrying surcharge loads typically require engineered designs—check local requirements or contact CAMO support at (616) 538-8000 or customerservice@camofasteners.com.
