A framing nailer is the ideal type of nail gun for all varieties of fence. Because they use long nails, framing nailers are capable of creating secure and durable fences in no time at all. Using a framing nailer for fence pickets will greatly reduce the time and effort it would take to construct a fence manually. With their effectiveness and efficiency at driving nails through stronger building materials, framing nailers get your fence built without needing to spend hours on end hammering away. You can theoretically use a finish nailer for fence pickets, but it is ill-advised. The shorter and thinner nails they use are less effective at securing the fence posts, and are more prone to snaps and breaks.  Thicker fences won’t be secured at all, as the nails won’t be able to drive all the way through the materials. When you’re building a fence, a framing nailer is the best choice.
