Metabo HPT Roofing Nailers
Metabo HPT is the brand that used to be Hitachi — same Japanese factory, same NV45 design, new logo. The NV45AB2 is the pneumatic coil roofer that earned the cult following: side-load magazine, tool-less depth dial, and a build quality that absolutely outlasts the price. Below: every Metabo HPT roofing nailer we stock.

Metabo HPT and the older Hitachi NV45 series are mechanically the same gun. Parts cross over, rebuild kits cross over, and depth dials read the same numbers.
Best pick for your job
Match the gun to the work — these are the picks pros reach for in each scenario.
Mid-budget production crew
Daily roofing without the MAX premium.
Pro build at a working-pro price — best value pneumatic in the class.
Side-load loading speed
You reload coils on the deck, fast.
Side-load magazine is the fastest reload pattern in the category.
Standard coil nails
Daily-driver shingle nail.
Standard 15° wire-collated — fits every NV45.
High-wind / hurricane
HVHZ and code zones.
Same magazine, ~40% more pull-out strength.
Coastal & cedar work
Salt air, cedar shingles.
304 or 316 stainless — galvanized rusts through cedar in a season.
Replacement parts
O-rings, driver blades, depth dials.
Hitachi/Metabo HPT crossover parts — easy to source.
Why Metabo HPT (Hitachi) NV45AB2 has a contractor cult following
The same Hitachi gun, new sticker
When Hitachi spun off its power tool division in 2017 it became Metabo HPT in North America. The NV45 didn't change — same Japanese factory, same internals, same magnesium body. If you ever ran a Hitachi NV45AB and loved it, the Metabo HPT NV45AB2 is the same tool.
That's important because the NV45 has been a pro-roofer favorite since the early 2000s for one reason: the build outlasts the price.
Side-load magazine — the underrated feature
Most coil roofing nailers load through the bottom of the canister. The NV45AB2 loads through a hinged side door. On a roof that means you can drop a fresh coil without taking the gun off your hip — the loading motion stays in your blind spot, and the nails seat themselves on the wire spool guide.
Production crews who time their squares-per-hour notice the difference.
What it competes with
The NV45AB2 sits between the budget Bostitch RN46 and the premium MAX CN445R3. It's heavier than both (5.5 lbs vs 4.9 and 5.1) but cheaper than the MAX and built tougher than the Bostitch. For most working pros, that's the sweet spot.
