Most every craftsman understands the true value of the nail. However, far fewer realize just how many types of nails actually exist. Of these types of nails, many vary significantly in size, shape, and composition.
Likewise, these nails also differ in their intended uses. This places increased importance upon familiarizing yourself with all current market offerings.
In order to make the most out of any project, one must be capable of choosing the perfect nail for the task at hand. While this might seem somewhat confusing at first, proficiency in such a matter is quickly gained with a little experience.
The following are a number of today’s most commonly used nails, as well as a general description pertaining to the uses of each.

Parts of a Nail
Nails come in multiple shapes, each with its own purpose.
- Round headed nails are often used for general-purpose fastening and construction. The round head allows good contact with the hammer but creates a rougher finish than other nail types.
- Flat headed nails are round and relatively large. They make driving a nail easier and reduce the risk of a nail’s head pulling through a given work surface.
- Checkered heads have a raised pattern, which helps prevent the hammer from slipping off the nail.
- Countersink and cupped heads are small, and not much larger than the diameter of the shank. They drive below the surface of the wood, to minimize nail visibility. Cupped heads allow one to easily fill such nail holes for a smooth finish.
- Clipped heads are relatively small D-shaped heads designed for use in nail guns. This clipped-style head allows for nails of this design to be joined for use in a nailer.
The shank is the middle part of the nail that is instrumental in providing strength. There are several different types of nail shanks.
- A smooth shank is the easiest to drive but offers the least amount of resistance against pulling out.
- A spiral shank rotates the nail as you drive it, much like threads on a screw. The thread or flute on the shank makes the nail easier to drive and helps keep the nail in place. Spiral-shank nails are commonly used for nailing hardwood flooring. Nails with spiral shanks are also often known as screw nails.
- Ring-shank nails, also known as annular nails, are often used with softer woods. Like a spiral shank nail, ring-shank nails lock into wood fibers to provide extra holding strength.
A nail’s point is its sharp outer tip, which is instrumental in penetrating wood surfaces.
- Diamond-shaped points are typical on nails designed for general use and make nails of this construction easier to drive. Long diamond-shaped points also help minimize the splitting of the wood.
- A blunt point makes a nail harder to drive, but less likely to split a work piece.

Materials and Coatings
A nail’s external finish or coating helps determine what projects it is best reserved for use with. Steel is the most common material used in nail construction, but is also susceptible to corrosion.
Steel nails that will be used in decking or other areas that come in contact with moisture, need to have a corrosion resistant coating. Meanwhile, bright nails consist of untreated steel, and are suitable for interior use only.
- Black phosphate coatings give nails a gray or black appearance. Black phosphate is a coating intended for indoor applications, and works well on drywall nails, since this coating creates excellent adhesion to both paint and drywall mud.
- Zinc plating adds a silvery or gold tint to any nail. Zinc-plated nails have some corrosion resistance, but standard zinc plating is thin and best used for indoor applications.
- Hot-dipped galvanized nails work well for outdoor use, due to their thicker zinc coating. This finish adds a flat, gray color. Hot-dipped galvanized nails are suitable for use with pressure-treated lumber, which can corrode unprotected steel. However, hot dipped galvanized nails don’t work well with wood species such as cedar and redwood. The coating reacts with oils in the lumber and can cause staining.
- Vinyl coatings on fasteners make them easier to drive, and increase their holding strength.
- Paint, brass, bronze, and nickel platings are best used for indoor applications.
Types of Nails
Like a typical claw hammer, a common nail can be utilized for everyday projects, such as construction work, framing, and woodworking projects. This type of nail features a round head and sturdy shank that provides substantial strength.
The common nail is best reserved for jobs where strength is more important than the appearance of the nail.
A box nail has a similar design to the common nail. However, the shank of a box nail is narrower. This means that box nails do not possess the same level of strength as that of the common nail, and are not appropriate for major structural jobs.
The smaller diameter of the shank does reduce the probability of splitting the wood when driving the nail.
Brad nails are a smaller variety of finish nails. They are ideal for more precise woodworking and craft work, but do not possess the same holding strength as a finish nail.
Brad nails have heads that are only slightly bigger than the diameter of the shaft of the brad. Often brads are installed using a pneumatic nail gun.

Also known as: Finish Nail
Finishing or finish nails are quite often used in carpentry and cabinetry work, where there is a need to conceal the nail used. They have small heads that can be countersunk below the surface of the wood with the use of a nail set, thus making them an excellent choice for molding work.
The finishing nail features a small diameter shaft, which reduces the risk of splitting.

Sinker nails are typically used for framing and general construction jobs. These nails feature checkered heads that prevent the framing hammer from sliding off while driving.
Nails of this type are designed to be driven flush with wood surfaces. Sinker nails also have vinyl covered shanks that provide lubrication for easier driving and increased holding power.
Due to their corrosion resistant composition, deck nails are the preferred choice for use with treated lumber. Deck nails customarily have checkered heads for better contact with the head of a hammer.
The smaller diameter shafts, characteristic of most deck nails, minimize splitting and often feature rings or spiral flutes to enhance holding power.
Drywall nails are designed specifically for the job of installing drywall. They have large round heads that are designed to be countersunk for concealment, and minimize the possibility of tearing drywall board.
Drywall nails also feature long diamond shaped points, which reduce the splitting of wall studs. Drywall nails are available with both smooth and ringed shanks, the latter of which enhances holding power.
Flooring nails are designed to be used in pneumatic nail guns, for the purpose of installing wood flooring. They are available in 16, 18, or 20 gauge sizes, which allow for flooring expansion/contraction, and greater holding power.
The higher the gauge number, the thinner the nail, and the less likely splitting becomes.
Framing nails, like common nails, are generally used for larger framing and craft projects, where superior hold and strength are necessary.
These nails are commonly used in framing nail guns, and come in a variety of shank and head configurations for use with specific nailers. It is commonplace for framing nails to be driven flush into the wood.
Roofing nails are intended for securing asphalt shingles, roof felt, roof decking and sheathing. These nails are exposed to the elements so they generally are made of aluminum or have corrosion resistant finishes.
Oftentimes, roofing nails feature a gasket under their larger than normal nail head to create a weather resistant seal.
Cut nails are quite robust, and are often used in a nailing machine for easier handling. Nails of this configuration are often used when installing flooring.
These nails are cut from a steel plate, leaving a distinctive wedge shape that is quite unmistakable. Cut nails are known for providing an impressive grip that is highly sought after in the flooring business.
Also known as: Double-Headed Nail, Scaffold Nail
Duplex nails are essentially two nails in one. They are used for temporarily constructing scaffolding, or forms for concrete projects.
They are designed with two heads along a central shank. The first head secures the nail against the wood, while the second head allows for easy removal.
Masonry nails are designed to fasten wood to brick, concrete block, and mortar. They are constructed of hardened steel with longitudinal grooves along the length of the nail’s shank, to assist with penetration of very hard materials.
Concrete nails are made of high-carbon hardened steel, and feature fluted shafts that help them easily sink into concrete. These nails are driven through boards into the concrete below.
Typically nails of this type are cheap and hold well, as long as at least 3/4 inch penetrates into the concrete. Concrete nails are shaped like thick common nails, and are extremely hard to pull out.
A siding nail is used to secure wood or siding to a structure. They are made with corrosion resistant material, or feature a corrosion resistant finish, as such nails are regularly exposed to the elements.
Siding nails often have small heads, so that they are extremely difficult to see after installation. These nails feature a ringed or spiral shank for extra holding strength.
Joist Hanger Nail
Joist hangers are brackets used for adding strength and rigidity to connections. These connections will have wood pieces meeting at a 90-degree angle. In most cases, they are used in major construction with joists and trusses.
Joist hanger nails are mostly made of stainless steel or hardened steel. Joist hanger nails also have various options for shanks. The most common shank options include smooth, barbed, and ring.
Weatherstripping nails are designed to be usable for any weather conditions. They are used to secure weatherstripping to windows and doors.
Weatherstrip nails come with a sharp point combined with a barbed shank. These two features make it easy to securely install the nail into position. They are most commonly constructed of copper because such material can hold up quite well against different weather conditions.
Pole Barn Nail
Pole barn nails are constructed with ring shanks for holding strength and a corrosion resistant finish for compatibility with pressure treated wood.
These types of nails are for construction projects that use wood poles set in the ground to form the foundation of the structure. They are commonly found in sizes ranging from about 4 to 8 inches.
Connector nails are designed for attaching structural hardware such as framing angles and rafter ties. They are used in nailer guns for installing joist hangers, straps, framing anchors/ties, and seismic/hurricane ties.
The heads are generally marked for easier nail identification during inspections and are designed to reduce nail bending when driven into hardware.
Cap nails are used to attach roofing felt, house wrap, tar paper, and insulation foam board. Unlike galvanized nails, a cap nail has a steel spiral shank that helps keep the fastener in place and a large polyethylene cap to prevent leaks.
Trim nails are designed for exterior use on homes. They secure home gutters, fascia, and soffit board as well as exterior trim. They are generally of a galvanized composition to withstand the elements.
Pin nails are used for delicate fastening jobs and are the thinnest and shortest of all finishing nails. These nails come in strips and are installed in a nail gun. They have a very small diameter (23 gauge) and no head, so they leave a very small entry point.
Annular Ring Nail
Also known as: Annular Ring Shank
Annular ring shank nails are commonly used to hold clapboards or shingles in place on home exteriors. These nails are most commonly of a galvanized construction.
Annular ring nails are thin nails, lined with rings for added holding power, and are resistant to rust.
A tack nail is a short nail with a wide, flat head or round head that is used for fixing carpets to floorboards and for stretching fabric onto wood. The lightweight nail is also commonly used for cabinet-making and for fixing small moldings into place.
The rounded head tack nail is used frequently with upholstery.
Panel Board Nail
Panel board nails have small, round heads and are used for fastening wall panels to studs or furring. They’re often available painted in different colors to match the panels you’re installing.
It has a ring shank for greater holding power in medium and soft woods.
Furniture Chair Nail
Furniture chair nails protect hardwood, ceramic tile, linoleum & hard surfaces from mars & scratches. They are designed for application on straight wooden furniture legs while reducing friction and noise while moving furniture.
Also known as: Upholstery Tack
Furniture nails or upholstery tacks are small nails with relatively large, decorative heads. They have two functions, to adhere upholstery to wood and to be decorative.
Spiral Shank Nail
Spiral shank nails turn as they are driven into wood. Due to the spiral shank design, they work like wood screws in the sense that they thread into the fibers of the hardwood as you drive them.
These nails are also designed to handle the dense materials better thanks to the use of reinforced steel. They are commonly used for squeak-free hardwood flooring and decking, siding, or in framing that is susceptible to high winds and moisture.
Rose Head Nail
Rose head nails are a solid steel forged nail that is good for framing, face nailing, scaffolding, and soft wood floors. They get their name from the hammered head that often resembles rose petals.
The forged look is desirable when you are seeking an antiqued look for the piece you are using them on. Quite often rose head nails are used in furniture repair and cabinetry due to this appearance.
The nails come with quite an outstanding durability plus holding power.
Hammer Drive Pin Anchor
A hammer drive pin anchor is used mostly for light-duty fastening activities and is quite versatile. They are installed by pre-drilling a hole and then striking the pin anchor with a hammer, thus driving the nail into the anchor body, expanding the anchor to form a tight fit.
Hammer drive pin anchors are used in such materials as brick and concrete and tend to be of a permanent application.
Common Nail Sizes
Nail sizing originated in England. Sizes of nails were named for how much it would cost to buy 100 of them in the same size. If 100 nails cost four pence, then the nail size was termed “four penny” nails.
In modern day, nail sizes correspond with the nail’s measurement for the head to the tip of the point. However, nail length is still indicated by the letter ‘’d”, as a throwback to the use of “penny” in earlier days. Each increase in the nail size corresponds to a ¼ inch longer in length.
Nail gauge size indicates the thickness of the shank of the nail. The higher the nail gauge the thinner the diameter is, thus a 15 gauge nail is thinner than a 14 gauge. It is also a measure of the strength of the nail. The smaller the gauge, the stronger the nail strength.
These are the common nail sizes and their corresponding length:
