Fasteners play a critical role in the construction of all sorts of everyday objects. If you’ve done any DIY projects, you’ve likely used fasteners to help get the job done. At All Points Fasteners, we’re passionate about the role quality fasteners can play for handy homeowners and professionals alike. Let’s take a moment to define fasteners and overview some of the different types, as well as the various uses for them.

What Is a Fastener?

Let’s start by defining what a fastener is. The term fasteners encompasses a fairly broad category of tools, such as screws, nuts and bolts, that share a common purpose: tomechanicallyhold objects together. Of course, things like glue can fulfill this function, but glue is not a type of fastener. Therefore, we need to add to our definition. Hardware fasteners mechanically hold objects together.

Typically, fasteners form a non-permanent joint. In other words, when you use a fastener to connect two components, you can remove it, and the separate pieces should come apart without suffering any damage. The same wouldn’t be the case with a welded joint, for instance. The one exception to this rule are rivets, which fall under the category of fasteners, but create permanent joints.

Though most fasteners form a non-permanent joint, this does not mean you only use fasteners when you want to be able to take something apart, and it doesn’t mean the joint is weak by any means. Fasteners can reliably hold together objects that can experience a great degree of stress.That means they’re a great choice for permanent and non-permanent joints alike, providing versatility for the type of project you want to use them for.

Different Types of Fasteners

Mechanical fasteners come in many forms, including screws, nails, nuts, bolts, washers, anchors and rivets. Each of these different types of fasteners is a category unto itself, with many types to choose from. If you’ve ever been in a fastener aisle at a hardware store, you know how many different types of fasteners are out there. Let’s look at each of these common examples of fasteners and break them down a bit further.

1. Screws

For many people, when they think of fasteners,screwsare the first thing to come to mind. Screw fasteners are one of the most versatile types of fasteners out there. Theirthreaded shafts give them durable holding power, and unlike a bolt, they don’t require anything to hold them in place. Typically, you use a drill to make a pilot hole in a material and then use a screwdriver to drive the screw in place. Screws come in a wide variety of types and sizes. Some of the most common types of screws include:

• Wood screwshave coarse threads and a tapered head.
• Deck screwsare similar to wood screws, but include self-tapping designs and corrosion resistance for outdoor applications.
• Drywall screwsfeature a self-tapping head that can countersink without causing damage to drywall.
• Sheet metal screwshave sharper threads for connecting metal to other materials.
• Machine screwshave a uniform thickness and don’t taper off at the bottom.
• Masonry Screws A masonry screw is specially designed to cut into concrete and brick. A drywall screw has twin threads to allow for quick, easy installation.
• Board screw This is designed specifically for wood or wood-type materials such as MDF or fibre board. They are self-tapping in as much as they will tap their own threads and do not need to be used with a pre threaded insert. It has a sharp point for easy starting and holds a grip within the wood so it will not slip.
• Exterior screw This is treated with an anti-rust coating to prevent corrosion or rust and is ideal for decking, joists or fences.

Size:

Be sure to choose a screw that is long enough for the job. If you are joining two materials together, you want to choose something

that is long enough to penetrate and grab both pieces. A screw that is too short may not be able to keep the materials fastened. A screw that is too long, on the other hand, may damage the wood on the other end.

You also want to choose the right diameter for the job as well. A screw that is too large may look unattractive or split softer, more fragile wood. On the other hand, a screw that is too small may not hold the materials well.

Heads:

Screws also have their own types of heads. They can be flat, which will allow you to countersink the screw into the material; rounded heads, which tend to be more decorative; or flanged, which eliminate the need for washers. You also have a choice in what type of drive you use on the screw. The most popular drives for contractors are:

• Hexagonal, which fits in magnetic bits and drive quickly; and
• Square, which doesn’t strip as quickly as others.
• Other less common drives include slotted, quadrex and Torx.

For the best results, chose the right screw for your application. If you’re not sure what you need, go ahead and give us a call. We’ll be more than happy to help you figure out what self tapping screw will do the job for you.

2. Nails

Nails have been used since ancient times, and they are still an everyday household item. You can easily spot the difference between a screw and a nail because a nail doesn’t have threading. While a nail doesn’t provide the same holding power a screw does, it has greater shear strength, making it the better choice for some applications.

Many types of nails take their names from their applications, which can make it a snap to find the right variety of nail for a job.They typically have specific characteristics designed for working with the materials or application at hand.

Some common kindsof nailsinclude the following:

• Common nailshave a thicker shank for greater holding power for many different applications, but the thick head will be visible on most projects.
• Box nailsoffer easier driving with a steel construction and diamond-point tip.
• Brad nailscan easily blend into wood trim.
• Finishing nailsare for more detailed work and have a small, flat head designed to blend in with project finishes, such as those on crown molding.
• Drywall nailsare designed for easy concealment and reduced slippage.
• Flooring nailsare designed for use with various flooring materials.
• Framing nailscan include a variety of styles, often designed for flush installation and easy concealment.
• Roofing nailshave a wide head and are often corrosion-resistant.

3. Bolts, Nuts and Washers

Nuts and bolts are another common type of fastener. These two pieces work in tandem to hold components together. You insert the bolt through the two parts you want to join, then fasten it in place with a nut on the end.Here aresome of the most common types of bolts you’ll use:

• Carriage boltshave domed or countersunk heads with a square component under the heat to keep the bolt from moving while tightening the nut.
• Flange boltsinclude a circular flange beneath the head for distributing loads evenly.
• Plow boltsare for heavy-duty applications, such as heavy equipment, with non-protruding heads.
• Hex-head boltsare six-sided with machine threads.
• Square-head boltshave square heads, offering an easier grip for wrenches.
• Allen boltshave a hexagonal socket for use with Allen wrenches.

Beloware some of the most popular types of nutsand their designs:

• Coupling nutsare hex-shaped and join two male threads together.
• Flange nutshave a wide, serrated flange on one end that serves a similar function as a washer but without any added movement.
• Hex nutsare the most common variety, featuring a hex shape and internal threads.
• Lock nutsinclude designs to prevent loosening due to vibrations.
• Slotted nutshave sections cut out to create a locking mechanism with the help of a cotter ping.
• Square nutsfeature a square shape for greater surface area.
• Wheel nutsare designed for securing wheels onto vehicles.

Nuts and bolts can function on their own, but sometimes, you’ll want to add a washer in between. A washer is a flat disc with an opening in the center. This little piece can distribute the fastener’s load more evenly across the surface of the material. Some types of washers are:

• Beveled washersadd stability when attaching unparallel surfaces.
• Flat washersare round and thin.
• Lock washersuse various mechanisms to prevent nuts, screws and bolts from vibrating loose.
• Structural washersare thicker and used in heavy-duty applications.

4. Anchors

Anchorsget their name because they serve a similar function to a boat’s anchor, which embeds itself in the seabed to keep a ship from moving. Generally, people use these fasteners to connect something to a material like drywall or concrete. They embed themselves in the material and hold the object you’re affixing in place. Some common types of anchors include:

• Internally threaded anchors
• Externally threaded anchors
• Masonry screw and pin anchors
• Screw anchors
• Hollow wall anchors
• Sleeve anchors
• Drive anchors

5. Rivets

A rivetcreates a permanent joint between two objects. They consist of a cylindrical shaft with a head on one end and a tail on the other. You usea unique tool to expand the tail, so the rivet stays in place.Rivets are remarkably durable, compared to other types of fasteners. Some common types of rivets include:

• Blind rivets
• Semi-tubular rivets
• Solid rivets
• Split rivets
• Drive rivets

Different Uses for Fasteners

What are fasteners used for? That question is somewhat tricky to answer, because fasteners have nearly limitless applications. Homeowners are likely to use fasteners for many DIY projects and basic household tasks. Workers in various industries can use industrial fasteners for all sorts of projects. If you need to attach two components, a fastener is likely the way you’ll do so. Here are some examples of common fastener uses.

• Vehicle assembly:You can find small fasteners throughout an automobile, including under the hood, in the suspension system and wherever else there is a connection between two parts or components, such as lock nuts on tires.
• Picture hanging:Small fasteners are prevalent in virtually every area with decorations hanging on the walls. Homeowners and other decorators use them when placing pictures and for other essential purposes.
• Building and construction:A metal fastener can serve multiple purposes to ensure materials stay together during construction projects.
• Furniture assembly:Furniture makers rely on fasteners when assembling their products and preparing them for sale to customers.
• Cabinet installation:Home improvement contractors need an assortment of fasteners when working on kitchen cabinet installation and renovation projects.
• Electronics manufacturing:Fasteners play a prominent role in the production of electronic machinery, components and goods used in the workplace and at home.
• Wall installation:Workers use anchors in tandem with screws to create firm mounts on drywall panels.
• Roofing projects:Roofing nails and framing nails are essentialwhen installing new roofs or conducting repairs and maintenance on existing structures.
• Woodworking:Not all fasteners are for holding two metal objects together. Carpenters and other construction and building professionals use wood screws to form solid connections between parts made of plywood and other wood materials.
• Flooring installation:Companies require flooring nails when installing some types of products in homes, office buildings, factories, warehouses and commercial and retail establishments.

The list could go on and on. Look around your home or business, and you’ll see fasteners holding countless objects together.

What Are the Benefits of Using Small Fasteners in Manufacturing?

Screw fasteners are prevalent in numerous industries, including manufacturing. Some advantages of using them in this area include:

• Increased designing flexibility:Fastener screws give designers and engineers more options when creating products. For example, companies that manufacture electronic devices like laptops and tablets can make these items less expensive for consumers by using fasteners instead of welds and adhesives when attaching specific parts and components. Screws also make these items easier to repair.
• Reduced waste:Many products require the assembling of multiple parts and components. Fasteners enable companies to complete the process with fewer materials, which generates less waste and lowers production costs. Manufacturers only need to create small, pre-drilled holes to accommodate screws, nuts and bolts to facilitate the final assembly.
• Lower product weight:Several industries are now turning to lighter, more agile products to reduce manufacturing costs, improve their appearance and make objects easier to handle and use. Small screws are perfect for these items, as they meet the basic fastening requirements and lower the product’s weight.
