Meet the CAMO 5/16 in. Multi-Ply Ledger + Flat Head Structural Screw — a purpose-built fastener that brings strength, speed, and a clean, flush finish to exterior framing. Designed to secure ledger boards and 2-ply engineered beams, this 3-1/2" x 5/16" screw is the reliable choice when you need a durable connection that lasts.

Why this screw stands out

• Code-compliant and exterior-coated for dependable performance in outdoor applications. It’s built to meet modern framing standards while standing up to the elements.
• 3-1/2" length for solid connections — specifically engineered to fasten ledger boards and 2-ply engineered beams, with a design that minimizes preparation while maximizing grip.
• Replacement for 1/2" lag screws — a versatile alternative for general construction projects where a smaller diameter with strong, persistent hold is advantageous.
• PROTECH Ultra 4-layer coating delivers superior corrosion resistance, helping connections endure outdoor conditions and long-term use without sacrificing appearance.
• Starts fast, drives easy, finishes flush — the CAMO engineering behind these screws is meant to reduce driving effort and leave a clean, low-profile head.
• 50-count box provides ample supply for deck projects, framing multiple ledger connections, or larger retrofit jobs.

Ideal use cases

• Securing ledger boards to framing to form exterior decks with a solid, code-compliant connection.
• Joining 2-ply engineered beams where a strong, flush-fitting fastener is preferred over traditional lag screws.
• Outdoor framing projects where corrosion resistance and long-term durability are critical, such as homes, gazebos, and terraces.

What you gain with CAMO 5/16 in. Multi-Ply Ledger screws

• Reliable, code-certified performance that supports safe, compliant construction.
• Cleaner aesthetics and a flush finish that reduces snags and improves overall appearance of the completed structure.
• Enhanced drive experience thanks to optimized geometry designed to start and finish with minimal effort.

Practical tips for maximum results

1. Plan ledger connections with the 3-1/2" length to ensure a secure bite through ledger boards and into the supporting framing.
2. Follow local code requirements (IBC/IRC) to confirm appropriate use and spacing for ledger and beam connections.
3. Use a compatible driver and setting to take full advantage of the ground-breaking CAMO drive system, ensuring a flush finish every time.
4. Store in a dry area to preserve coating integrity and extend the life of the screws between projects.

Whether you’re upgrading outdoor framing, replacing lag screws with a cleaner, more efficient solution, or tackling a ledger-to-beam connection, the CAMO 5/16 in. Multi-Ply Ledger + Flat Head Structural Screw delivers strong performance, easy installation, and a lasting, aesthetically pleasing finish.
