Bright nails have no finish. They can cause rust streaks if they are used in siding or decking, for example.
A common way of making nails corrosion-resistant is to coat them with zinc. Hot-dipped (H.D.) nails have been galvanized by dipping them in molten zinc. Electrogalvanized nails are plated with zinc, and are not as corrosion-resistant as hot-dipped nails. A third process peens zinc onto the nail. By roughening the nail's surface, all these treatments–but especially hot-dipping–increase the holding power of the nail.
Blued nails have very little resistance to corrosion and are meant to be used indoors.
Shanks
Most nails have smooth shanks.
Ring-shank nails are used with softwood, in situations where the nail will be pushed from side to side, which tends to enlarge the hole and free smooth-shank nails.
Spiral-shank nails are mostly used with hardwood. They have great holding power.
Heads
Most nails have flat heads, in some cases very large ones.
The brad head is found on finishing nails and brads. Usually it is cupped; that is, it has a small depression in the middle of the head that serves to steady a nail set.
Duplex heads are used where the nail must be removed later, for example, in constructing movie sets.
Points
Most nails have a diamond point, a 4-sided pyramid. Some however, have needle points, and a few types have a chisel point or a duckbill point.
Materials
Besides high-carbon and low-carbon steel, nails are available in types 304 and 316 stainless steel. Stainless steel nails are slightly less strong than ordinary steel nails and are about three times as expensive as galvanized nails, but they are much more rust resistant.
Aluminum nails are not strong enough for most structural framing and are primarily used to fasten aluminum siding or screening.
Copper nails are used in roofing and in marine applications.
Special types
Cut nails
Most nails made today are wire nails, machine-made from mild steel wire and more or less round. In earlier times the cut nail was more common. Cut nails, which are still made, are cut from a steel or iron plate and so have a rectangular cross section. In most fields they are now a specialty item prized for their quaint appearance. They are not inferior to wire nails, however; in fact their holding power is about 1.5 times greater than that of a wire nail of the same length–even more in end grain–but they are more expensive to manufacture.
Power nailer nails
Nails for power nailers, the professional's replacement for the hammer, are sold by count, not by weight. These machines require nails that have been stuck together in coils or sticks (like the staples for an office stapler). A typical coil holds about 100 to 300 nails and a stick about 100. Each machine has particular requirements (for example, in some sticks the nails are tilted at 31° and in others 22°). Nails should be purchased with a specific make and model of nailer in mind, though there is some interchangability.
