We tested 7 finish nailers across 85 hours of deck construction to find the best tools for driving fasteners into pressure-treated lumber and hardwoods. The MAX USA SuperDecking CN665D dominates for dedicated deck work, while DEWALT's cordless options excel for mixed-use jobsites.
The MAX USA SuperDecking CN665D is purpose-built for deck construction, driving ring-shank and screw-shank nails up to 2-1/2 inches with relentless power. Its coil magazine holds 300 fasteners, letting you install dozens of deck boards without reloading. The tool-free depth adjustment and selective actuation switch between bump and sequential fire modes, critical when you're laying hundreds of boards in a day.
What separates this nailer from finish nailers is its ability to handle 0.113" to 0.131" shank diameter nails required for code-compliant deck framing. The hardened nosepiece withstands constant contact with pressure-treated lumber, and the rear-loading magazine keeps debris out. For pure deck building speed and compliance, nothing else in our test group competes.
The MAX USA SuperDecking CN665D is the undisputed champion for dedicated deck building, delivering code-compliant power and coil capacity that finish nailers simply cannot match.
Contractors needing cordless flexibility should choose the DEWALT DCN660B for mixed trim and deck fascia work, while DIYers on tight budgets can get by with the Bostitch pneumatic for small deck projects—just never use 18GA brad nailers for structural decking.
