Many types of wall anchors can be used in a facility—choosing the right kind of fastener by looking at the entire construction and identifying the anchoring needs. This includes details like raw material usage, weight and other specifics.

Wall anchors are used for different purposes, and their uses vary depending on load/weight capabilities, environmental conditions and base material. To find the appropriate fastener, you need to understand the different types.

Here are some of the most commonly used anchors and their functions:

  • Wedge anchor can fasten fixtures to brick and block construction project tasks that need to bear weight.
  • Hollow wall and wallboard anchors can be used to secure items to hollow, porous, or brittle walls like brick, concrete, and drywall.
  • Adhesive anchors can secure bolts, rods and rebar in concrete and masonry work and deliver consistent performance in various weather conditions.
  • Drop-in anchors can anchor shelves, pipes and machinery into concrete or solid base materials.
  • Hammer anchors or drive pin anchors can be used for a permanent installation in light-duty or heavy-duty applications.
  • Sleeve anchors can anchor the substrate material like steel, aluminum, wood, doors, etc., in a hole drilled in concrete, brick or block.
  • Stud anchors connect steel framing to concrete to anchor pipe run supports, blowers, pumps, and support racks.
  • Expansion shield anchors or lag shields are used to attach items to a masonry or concrete surface that will have much weight.
  • Spring anchors are a quick and cheap way to keep extension springs in place while still being able to control the weight load.
  • Screwbolt anchors or Screw-Bolt+ anchors are heavy-duty, rugged masonry anchors that help secure wood, concrete and masonry components.
  • Toggle anchors can anchor light to medium weight-bearing support from the hollow drywall of walls and ceiling.

Fasteners are products used to join or connect two or more pieces of material, such as bolts, nails, screws, magnets etc. Fasteners can be made from various materials, including metals, plastics, and composites. There are many different types of fasteners, each with its unique application. Fasteners are an essential part of many products, including automobiles, aircraft, and construction materials. Fasteners are an integral part of any project, big or small, and choosing the right ones can make all the difference.

Here are a few things to keep in mind when using fasteners for your next project:

  • Function: What do you need the fasteners to do? Hold two pieces of wood together? Keep a pipe in place? Be sure to predrill holes for the fasteners, if needed.
  • Material: What is the fastener going to be made of? Will it be exposed to the elements? Make sure the fastener is the right size and type for the material you're using. Mismatched metals can cause corrosion so pair your fasteners accordingly.
  • Size: What size fastener do you need? Nuts and washers are sized in both U.S. and metric measurements.
  • Head Style: The head of the fastener should be appropriate for the application and the material. Typical head styles include pan, round, button, flat, and truss.
  • Drive Type: The drive type is determined by the tool you'll use to install the fastener. The most common types are Phillips, slotted, hex, and square. Always use the correct size drive type to avoid stripping your fastener head. 
  • Thread Type: The thread type determines how the fastener will be held in place. Be careful not to over-tighten pins as they can damage the bolt's threads.
Many different fasteners can be used for various applications. Read on for information on the more popular fastener types and their intended use.
  • Screws are fasteners that can be used for wood, drywall, machinery, and other applications.

A nail has three basic parts: 

  • A nail point drives into the workpieces
  • A nail shank or shaft secures the workpieces together and provides much of the strength and holding power.
  • A nailhead allows you to drive the fastener and helps prevent the nail from pulling through the workpieces.

The type of nail you use will depend on the project you are working on. Different nails are suitable for other things. Some nails are good for holding things together, some for being outside, and some for being hidden. Here are some of the most common nails and what they are suitable for.

Common nails are suitable for general projects where the nail's strength is more important than how it looks. These nails have a round head and a sturdy shank.

Framing nails are used for framing projects and craft projects, just like common nails. They come in various types, with smooth, ring, spiral shanks and round or clipped heads. You can find them collated for use in framing nailers.

Box nails have a design like common nails but with a narrower shank. This smaller diameter reduces the likelihood of splitting the wood components as you drive the nail. It also means the nails don't have the strength of common nails.

Sinker nails have a checkered head to prevent the hammer from slipping. The head is designed to be level with the surface. The shank is usually coated with vinyl to make it easier to drive and hold better.

Deck nails often have a checkered head for better contact with the hammer, a smaller diameter shaft to minimize splitting, and a corrosion-resistant finish to be used outdoors and with treated lumber.

Roofing nails are used to secure materials like asphalt shingles and roof decking. They need to be strong and durable since they are exposed to the elements. Some roofing nails have a gasket under the head to create a weather-resistant seal.

Masonry nails fasten wood to brick, mortar, concrete block or uncured concrete. They are made from hardened steel and come in various shapes and sizes. Extruded masonry nails are usually short and thick, with round, fluted or grooved shanks. The flutes spin the nail as it's driven, making it easier to drive.

Siding nails are used to secure wood and fiber cement siding. They are made of corrosion-resistant material or have a corrosion-resistant finish. Siding nails may have small heads and ringed or spiral shanks.

Joist hanger nails are for attaching joist hangers to wood studs. The shank is strong, and the nails are often hot-dipped galvanized for exterior use and use with treated lumber.

Duplex nails are for projects that are only temporary, like scaffolding or making forms for concrete. They have two heads, which helps to make them easy to remove when the project is done.

Pole barn nails have a ring shank to make them stronger and a corrosion-resistant finish. This makes them suitable for projects where wood poles are set.

Connector nails attach hardware like framing angles and rafter ties to structures.

Cap nails have a plastic cap that goes under the nailhead. This is to secure materials like house wrap or insulation. The nails also have a spiral shank.

Trim nails are designed for exterior use on homes. They are used to secure home gutters, fascia and soffit board, and exterior trim.

Finish nails are used in fine carpentry and cabinetry and are suitable for molding. They have small heads that can be driven flush to the workpiece or countersunk, so they are not visible.

Brad nails are smaller, weaker versions of finish nails. They're suitable for woodworking, cabinetry and craftwork. Like finish nails, brad nails have heads only slightly larger than the diameter of the shaft to allow countersinking.

Pin nails are used with nailers. They have a small diameter (23 gauge) and no head. They can be used to secure thin veneer and small molding and trim pieces, but they don't have much holding power.

Drywall nails have large, round heads that may be dimpled or designed for countersinking. These features allow them to be easily driven below the surface of the wallboard for concealment and to minimize the tearing of drywall paper. Drywall nails with smooth shanks or ringed shanks to help keep them in place are available.

Panel board nails have small, round heads. They are used to attach wall panels to studs or furring. Some have ring shanks that hold power. They are often available in different colors to match the panels.

Flooring nails are unique nails used for installing wood flooring or securing flooring trim. There are different types of flooring nails, depending on what they are used for.

Furniture nails or upholstery nails are small nails with relatively large, decorative heads. Their primary function is to secure upholstery fabric to a wood frame.

Nails for nailers or nail guns are available in different types, including common, framing, finish, siding, and roofing. They are joined or collated into coils or strips and connected by wire, plastic, glue, or paper. The degree measurements indicate the angle at which the nails are collated. Make sure you match the nailhead type, collation type, and angle to your nailer.

Screws are one of the necessary fasteners used in construction and manufacturing. There are many different types of screws, each with its unique purpose.

The most common type of screws are:

  • Cabinet screws go into the wall to hold the cabinet in place.
  • Ceiling fan screws hold the blades or light globes on the ceiling fan.
  • Cement board screws are fully threaded and have a coating to resist corrosion, they are used to secure the backer board to wood and metal.
  • Concrete screws or concrete anchors fasten onto concrete or another masonry.
  • Deck screws are either wood or composite metal made for decks, fencing, and other outdoor projects.
  • Dowel screws are headless fasteners with lag thread at both ends and are used for joining two wood pieces.
  • Drywall screws are used for interior projects, such as attaching drywall to studs.
  • Gutter screws can be ceramic coated, copper, stainless steel or aluminum coated and are used to attach the gutters to the house.
  • Lag screws or Lag bolts are used to fasten heavy materials or components that need to handle large loads.
  • Landscape screws are for fastening landscape timbers together.
  • Machine screws are screws that go all the way through and secure metal components together.
  • Multi-material screws are made to be used in more than one type of material, like wood, sheet metal, drywall, masonry, and plastic.
  • Security screws or tamperproof screws are standard screws but with a unique head that requires a specialty driver orbit to be removed.
  • Sheet metal screws are screws that go through sheet metal or other soft materials.
  • Socket cap screws are headless with an internal hex socket that is cylindrical and raised.
  • Structural wood screws are designed like wood screws but are much stronger than regular wood screws and can act like lag screws or bolts.
  • Trim screws have a small head that can be concealed and are used to attach the trim to wood or metal studs.
  • Wallplate screws are machine screws that attach covers for light switches and outlets to electrical boxes.
  • Wood screws are screws that have sharp points and coarse threads that allow the screw to pull the wood pieces together tightly.

There are many different types of bolts available on the market today. Each type of bolt has its specific purpose and function.

The most common types of bolts are:

  • Anchor Bolts can be used in concrete foundations or walls.
  • Axle bolts allow you to attach wheels to equipment, such as mowers and wagons.
  • Body bolts are used in the automotive industry to attach fenders and other parts to a vehicle's body.
  • Carriage bolts have a smooth, finished look and are more secure than hex-head bolts.
  • Eyebolts have a loop or ring end and a threaded end to secure a chain or rope to wood, metal, or concrete surface.
  • Hanger bolts are headless fasteners with machined threads, driven into a predrilled hole in wood or similar material.
  • Hex bolt has a hexagonal head, which can be turned with a wrench, socket, ratchet, or drill/driver commonly used in construction and automotive applications.
  • Split bolts are used to securely connect two wires and come in different materials that work with different types of wires.
  • U-bolts have two threaded shanks and a rounded or flattened shape consisting of two nuts and a metal plate to secure the U-bolt against the item you're fastening.

Different nuts work with bolts to secure them tightly. Here are some of the most widely used hardware nuts with bolts:

  • Cap nuts or acorn nuts are domed-shaped nuts with a hexagonal driving surface used on projects such as outdoor playsets and fences.
  • Hex nuts have a six-sided drive surface commonly used with bolts to secure wood and metal components.
  • Nylon lock nuts are hexagonal nuts with a built-in nylon ring installed on a bolt, which increases friction and helps prevent the nut from rotating when they stop against the pin.
  • Square nuts have four large surfaces that are easy to grip and turn. Flat washers should be used with square nuts to prevent damage to the workpiece.
  • Wing nuts are built, so you don't need any tools; the wings let you turn your thumb and finger are used on drum kits, light stands, and other things that need to be changed.

Washers help distribute the load from a fastener evenly, help to prevent the hardware fastener from tearing through workpieces, or act as a spacer. Some washers also help to keep nuts and bolts securely fastened.

The more common type of washers are:

  • Structural
  • Conical or Spring
  • Countersunk washers or finishing washers
  • Fender washers
  • Flat washers
  • Sealing
  • Slotted
  • Spherical
  • Split lock
  • Tooth lock washers (external-tooth / internal-tooth)
  • Wave lock washers

One of the most common issues with fasteners is called thread galling, also known as cold welding. The bolts twist off, and the bolt's threads seize to the nut's thread. During the tightening process, pressure and friction build up between the two surfaces, breaking down protective oxides and causing the two surfaces to lock together. Thread galling is when threads freeze together, and it can cause the fastener to be twisted or ripped out. It is tough to remove the fastener without cutting or splitting the nut if this happens.

Here are a few tips to help you find the right fastener for your next project:

  1. Consider the material you're working with. Different materials require different types of fasteners.
  2. Think about the weight and size of the item you're attaching the fastener to. This will help you determine the size and strength of the fastener you need.
  3. Take into account the environment in which the fastener will be used. Different conditions (e.g., moisture, extreme temperatures) can affect the performance of different types of fasteners.

By following these tips, you can be sure to find a suitable fastener for your next project.
