Hi! My name is Matthew Christian from Tampa, Florida and on behalf of Expert Village, today we are here to talk about cordless nail guns. Let's take a moment and talk about nails. This particular manufacturer of cordless nail guns requires that you use only their nails. It is imperative that you don't try to use another manufacturer's nails in this manufacturer's gun. It may not work or it could damage your gun. But you will want to match the nails for the gun that you are using. This gun here is a trim nailer. It uses a rather thin nail and it is primarily used for fixing trim like baseboard, crown molding, door casing. The nail is relatively thin and is 16 gage and comes in an assortment of lengths depending upon what you are trying to nail and deep you need to go, if you are going through a half inch thick piece of baseboard and then a half inch sheet of drywall in order to get to a wooden stud, you may want to use something at least an inch and half long in order to make it through the baseboard and into the stud behind the drywall in the wall. These are inch and half and also 2 inch and they do come in various other lengths as well. I think the maximum on this gun is 2 1/2 inches. Besides this one here, we have what is called a framing nailer. This gun is primarily used for fastening 2 x 4 to 2 x 4 or for driving nails to fix a fence if you are putting up a new fence. But notice the framing nailer has a much thicker larger nail. It is a little more like the nails where used to seam and again, these are affixed together. These nails were designed for this gun. Again, do not try and use nails from another manufacturer on a different gun. Again, they do come in different sizes and lengths and the gage will stay the same but these are angled nails designed for this gun and these are also ring shank. Ring shank helps keep the nail in place so that the nail won't come out.
