Metabo HPT Collated Duplex Nail | 3-1/2 Inch | 21 Degree | Plastic Strip | For Use with NR3675DD | 50312-16D

These 50312-16D 3-1/2" Duplex Nails Work Great in My Metabo NR3675DD Duplex Nail Gun. These cannot possibly be an actual 16D nail. At least in my experience, just as others have said, you better have a real good pry bar or wonder bar to get these nails out. The heads are SUPER small and a hammer claw just comes right over the top. I don't mind. Still a heck of a lot easier to pull if needed than a non-duplex nail. Although- I consider these semi permanent. NOT temporary.

Box was already opened and damaged. A lot of the strips of nails are breaking/falling apart. I paid for nails for a duplex nail gun and half aren’t usable because the plastic breaks easily when grabbing a strip of nails out of the box.

This nailer, and nails are game changing in my business.

I was hoping this would be a game changer in my form set up and removal. The nails work great nailing, but the duplex head is to small for the claws on a hammer to pull the nails back out. We tried several hammers to try to remove the nails and the only thing that worked was using a second hammer to hammer the duplex head tight into the claws of the first hammer. It defeated the purpose of a duplex head if you can’t remove the nail efficiency. The duplex head needs to be redesigned so that the nail can be removed quickly after use.

Doesn't matter if your hammer is new or old, some heads pull fine, others round off.
