The next size up is the 18 gauge (1.02 mm diameter) fixing, often referred to as a " brad". The 23 gauge micro pin is rapidly gaining ground as users find that it leaves a much smaller hole than brad nails, thereby eliminating the time normally taken to fill holes and presenting a far better looking finished product. Lengths are normally in the range 3⁄ 8 to 1 + 1⁄ 4 inches (10 to 32 mm), although some industrial tool manufacturers supply up to 2 inches (51 mm). They are used for attaching everything from beadings, mouldings and so forth to furniture all the way up to medium-sized 7 to 8 inches (18 to 20 cm) baseboard, crown molding and casing. The smallest size of fasteners are normally 23 gauge (0.025 inches or 0.64 millimetres in diameter), commonly called "pin nailers" and generally have only a minimal head. Nail guns vary in the length and gauge (thickness) of nails they can drive.Īir compressor supplies air into a nail gun Industrial nailers designed for use against steel or concrete may have a self-loading action for the explosive caps, but most need nails to be loaded by hand. Nailers may also be of the 'coil' type where the fasteners come in wire or plastic collation, to be used with nail guns with a drum magazine the advantage is many more fasteners per load, but at the expense of extra weight. Full Round Head nails and ring shank nails provide greater resistance to pull out. Clip head nails are sometimes banned by state or local building codes. Some strip nailers use a clipped head so the nails can be closer together, which allows less frequent reloading. Some full head nail guns, especially those used for pallet making and roofing, use long plastic or wire collated coils. Nail guns use fasteners mounted in long clips (similar to a stick of staples) or collated in a paper or plastic carrier, depending on the design of the nailgun. With the original nail gun, the operator used it while standing and could nail 40-60 nails a minute. The first nail gun used air pressure and was introduced to the market in 1950 to speed the construction of housing floor sheathing and sub-floors. The wooden fuselage was nailed together and glued, and then the nails were removed. The nail gun was designed by Morris Pynoos, a civil engineer by training, for his work on Howard Hughes' Hughes H-4 Hercules (known as the Spruce Goose). ![]() Nail guns have in many ways replaced hammers as tools of choice among builders. It is usually driven by compressed air ( pneumatic), electromagnetism, highly flammable gases such as butane or propane, or, for powder-actuated tools, a small explosive charge. ![]() A nail gun, nailgun or nailer is a form of hammer used to drive nails into wood or other materials.
