Framing nailers are typically referred to as simply "nail guns" and use fasteners mounted in long strips (similar to a stick of staples) or collated in a paper or plastic carrier, depending on the design of the nail gun. Some full head nail guns, especially those used for pallet making and roofing, use long plastic or wire collated coils.
This nailer can handle a variety of jobs and stand up to some tough environments without getting damaged.
There are currently four different angles of straight framing nail clips: 21 degrees, 28 degrees, 30 degrees and 34 degrees. Nail clips can vary in length and gauge and even material type, but the important thing to remember is that if you have a 21-degree nailer, you can only use 21-degree nail clips. Additionally, each angle of framing nail clip is held together with a different type of material offering many pros and cons when it comes to speed and capacity. To further complicate things, there is also a 15-degree framing nail gun that will only accept a magazine that is coiled. These coils typically hold 200-300 framing nails slanted at 15 degrees.
21-Degree Framing Nailers: These nailers are capable of driving a full round head nail and the low angle is great for working in tight spaces. 21-degree nails are held together in plastic clips that shatter as the nails are being driven. This type of gun ejects pieces of plastic at high speed while you’re working, so it’s a good idea to wear your safety glasses while you work. The major drawback to 21-degree nails is the low capacity per clip. You can expect each clip to hold only about 64-70 nails, so for larger projects, you can expect to reload with more frequency. The advantage to the low capacity is the light weight and extreme portability of these guns.
30- and 34-Degree Framing Nailers: These guns give you the most radical advantage in tight spaces and are the most common nailers seen on construction sites. Generally, they can hold two full strips of nails of up to 94 nails each. These clips are held together with a strong paper tape, which leaves less of a mess on job sites and is safer for working in tight corners. The downside is the running theme with any nail gun: more nails, more weight. These are the heaviest of the straight clip nailers and will require some serious upper body strength for a full day’s work.
