Maze CLS223A 1-1/2" X .095 Double Hot Dip Galvanized Ring Shank 15 Degree Coil Nail 3200 Per Box

I love Maze nails, and these are the real thing, collated for your siding nailer. They ARE expensive and the plastic collating system is a bit shaky. You have to handle the coils with care so as not to have the nails start dropping out. If you can do that, and if you have a lot of cedar shingles to install, they're a lot faster than hand nailing and far better nails than the "galvanized" siding nails and staples available from Bostich and others.

Plastic collating is garbage. Bought 12000$ worth and they are useless. They come away from the collating and jam the gun, wasting a lot of time. Very disappointed

These folk make some super quality USA nails. They are not cheap in cost, but neither is have to replace nails that rotted away in 15 years. You get what you pay for/
