Yes there are many different kinds of siding nails from all over the world. Stores that sell nails buy/import nails from where-ever the labor/cost is cheapest. The importer uses a private label so the nails from one company in China will produced according to requirements and will be sold under many different brands in the US. The result is that the nails are not exactly the same from batch to batch. I have seen coils that measure from 3/16 to 1/4 inch between the nails. Closer to 1/4 inch is more ideal for your nailer. The (nv65ah) is listed as a 16 degree canister angle, however you probably purchased 15 degree nails because nothing else is available. Should be no problem assuming everything is working ok. When you insert nails into feeder, make sure that the first nailhead is positioned under the driver and not too far to the edge because the driver will bend the nail if not hitting dead center to the nail shaft. Ask for a sample section/ roll of different brands and type of nail to find the best nail for your gun. Best place to find nails is a fastener company that only sell nails/ nailers/compressors to contractors. For best results, make sure that the driver is squared/flat at the tip. If is not, remove the driver and grind it flat (do not grind too much). If driver and nails check out ok, then it may be time to replace springs/orings in feeder area. Go to and take a look at the breakdown of your gun and notice that there are several springs in the feeder area that will weaken over time/use. There should be two springs in doorlatch area, one on the feeder itself, and one large spring pushing on the feed piston. Good luck with your issue and email if you have question.

Hitachi nv65ah driver sticks after driving first nail

Most often with this tool it is because the driver is bent. Remove the 4 bolts on the head and pull the driver straight out to inspect it. It doesn't take a lot of bend to hang it up.
Let me know if this helps!

My Hitachi nv65ah nail gun won't set nails into 3/4 trim. I have played with the turn/screw set adjustment and it is set for the deepest setting. This gun was purchased second hand off e-bay but

If every nail is stopping at the exact same height, a likely reason is the tip of the driver is broken off so it's not long enought to drive the nails all the way to flush. If the height of the nails is slightly different you may have worn or broken o-ring(s) inside the gun and air is leaking around the driver's piston or elsewhere in the gun so that the driver isn't getting full pressure. You can take the gun apart and inspect the o-rings. If you push the driver all the way down the tip should come flush or slightly past the end of the nose piece (not the safety tip). Parts are easy to find online or at a service center if you have one nearby.

I have a craftsman roof nailer with plastic cover for nails broken where can i get one to fit

Best place for replacement parts is the address below.
Ez to order from and usually only takes 10 to 14 days to get the parts. Click on Hitachi logo then select coil nailers, then your model number. For local parts, look in the yellow page directory for fasteners. Fastener companies that sell nails and other supplies to contractors also have parts for Hitachi nailers. Check with several. Some will even repair the nailer for you if you buy nails from them.
Good luck.

Pieces of the coil are breaking off when firing my Hitachi NV65AH - what causes this?

If you are using wire coiled nails, this is a common issue and there really is noway to stop this, and is advisable to wear safety glasses when ever using a nail gun. I have had 1 of the wires come off a coil and literally pierce my cheek. If it would have hit me in the eye it would have done some serious damage.

NV65ah Hitachi nail gun "how do you remove the trigger piston"??

If you do not have a breakdown of the gun go here and select brand, then select coil nailer, finally look for your model number. With breakdown, find parts labeled 51 thru 54. The trigger pin (#53) and the retaining ring (#21) hold the trigger. Remove these then remove the trigger. Find several #51 roll pins on the gun and punch out the uppermost pin where the trigger valve is located (3mm size). The uppermost rollpin holds the trigger valve in-place. After you have removed the rollpin/s connect air supply to pop-out the trigger valve. Caution, use a heavy glove (or reduce pressure) to catch valve as it can come out with force. When incerting the rebuilt valve, use caution not to cut new orings as the valve is pushed in. Good luck and email if you have more questions.
