Construction Screw · 10 x 5 in - Lumber - Green Magni Coating - Fitsfast 10500SDSTS

What this product is for

This deck screw is used to fasten ACQ-treated lumber in outdoor wood construction such as deck boards, rails, stairs, and general exterior framing where a corrosion-resistant coated screw is required.

Use for

Use for pressure-treated wood, deck repairs, new deck construction, and other exterior wood-to-wood fastening where a #10 x 5 in screw length is appropriate. A 5 in length is approximately 127 mm.

Avoid for

Avoid using where stainless steel is specified for severe corrosion exposure, coastal environments, or where project documents require a different fastener material or approved connector system. Do not assume suitability for structural load connections unless the project specification confirms it.

Best for

Best for contractors and builders working with ACQ-treated lumber who need a coated exterior screw for longer wood fastening applications. For deck work, coated ACQ-compatible screws are commonly chosen to reduce corrosion risk compared with general interior screws.

Installed in

Typically installed in exterior decks, fences, stairs, pergolas, and other outdoor wood assemblies using pressure-treated lumber.

Why this product exists

ACQ-treated lumber is more corrosive to standard steel fasteners, so this product exists to provide a coated screw option intended for that environment. The longer 5 in size is typically selected where deeper wood penetration or thicker member build-up is needed. Actual suitability depends on member thickness, load, and local code requirements.

Compared with similar products

Compared with general wood screws, deck screws for ACQ lumber use corrosion-resistant coatings intended for pressure-treated wood. Compared with shorter deck screws, a 5 in screw provides deeper embedment but may require more driving torque and is typically used for heavier wood connections rather than standard deck board fastening. Drive style, point style, and head design could not be confirmed from source material and should be verified before purchase.
