For those who have gone through a variety of pneumatic staple, brad and nail guns when installing window casings, furniture trim and other decorative elements around the house, the NuMax SFN64 will let you do all these and more. This 16 gauge straight finish nailer is light and handy for most trim fittings around the house and in your craft or hobby projects.

Made by NuMax, which is a Georgia-based power tools manufacturer, the nailer is available at prices between $44 and $70. Its affordable pricing along with the lightweight, user-friendly operation and sturdy build makes it very popular among amateur DIYers who like to get their trim-work done quickly around the house. The NuMax SFN64 is designed for use with straight finish nails, and has several features that make it quite flexible in use.

Sturdy And Light For Household Trim, Hobby And Crafting

The air driven NuMax SFN64 weighs a very handy 4.5 pounds, so you can easily use it single-handed while you adjust trim with the other. It is designed to work with 1 inch to 1 1/2 inch 16 gauge nails, so as long as the nails have a straight finish, you can use the air nailer for a variety of projects. The manufacturers suggest some uses – decorative trim, window casings, and picture frame assembly, base moldings for door and windows, and furniture trim. You can also use it for hand railings, crown molding, shoe-making, making chairs etc. The NuMax 16 gauge SFN64 nail gun also lets you easily adjust the depth of drive, so you almost never have to pull out your hammer to set in proud nails. There are several special features that makes this air powered nailer so popular.

Enjoy Depth Adjustment Without Tools

The tool-free depth adjustment feature is a boon, letting you easily adjust the depth of drive to prevent nail heads from sinking under the surface. A nail will always be driven correctly from the SFN64 nailer if you adjust the depth of drive, and the nail head will sit flush with the surface of the work piece, eliminating the need for sealant or caulking.

Sturdiness and Great Value for Features

Many professionals with years of experience in trim installation and cabinetry often find it difficult to believe that a 2 1/2 inch nail capacity nailer can be available at such an affordable rate. The NuMax nail gun manages to do just that, with features that are worth every dollar. The feel of the nailer is sturdy and the results of fencing, baseboard installations, weekend projects, moldings and other reasonably heavy duty weekend projects will pleasantly surprise users who expect quality only from high end power tools.
