Code-compliant and exterior-coated, CAMO 5/16 in. Ledger + Multi-Ply Screws hold strong and finish flush in a variety of applications. Our 3-½ in. Ledger + Multi-Ply screw is specifically designed to fasten wood ledger boards and 2-ply engineered wood beams. They can also be used as a replacement for ½in. lag screws in general construction projects. They are third-party tested and certified IBC and IRC code compliant. These structural wood screws feature our proprietary PROTECH Ultra 4 four-layer coating system, offering superior corrosion resistance for long-lasting connections. It's the only screw coating on the market tested to ASTM G198 standard, which required 2X longer testing and 3X more samples than industry standard. CAMO Structural screws are engineered to start fast, drive easy, and finish flush so you can get the job done and get on your way.
