Types of Screws
When it comes to screws, there are many different types available for various applications. In this section, we’ll go over some of the most common types of screws and their uses.
Wood Screws
Wood screws are designed specifically for use with wood. They have a tapered shank and a sharp point, which makes them easy to drive into wood without splitting it. Wood screws come in a variety of sizes and lengths, and they can be used for a wide range of applications, including furniture assembly, cabinet installation, and general woodworking.

Machine screws are used for fastening metal parts together. They have a straight shank and a blunt end, and they are typically threaded all the way up to the head. Machine screws come in a range of sizes and lengths, and they are often used in machinery, electronics, and other precision applications.
Sheet Metal Screws
Sheet metal screws are designed for use with thin metal sheets. They have a sharp point and a threaded shank, and they are often self-tapping, meaning they can cut their own threads as they are driven into the metal. Sheet metal screws come in a variety of sizes and lengths, and they are commonly used in HVAC systems, roofing, and other sheet metal applications.
Masonry Screws
Masonry screws are designed for use with brick, concrete, and other masonry materials. They have a special thread design that allows them to grip the masonry material securely, and they often have a special coating to prevent corrosion. Masonry screws come in a variety of sizes and lengths, and they are commonly used for attaching fixtures to masonry surfaces.
Drywall Screws
Drywall screws are designed specifically for use with drywall. They have a sharp point and a threaded shank, and they are often self-tapping, meaning they can cut their own threads as they are driven into the drywall. Drywall screws come in a variety of sizes and lengths, and they are commonly used for attaching drywall to studs.
Decking Screws
Decking screws are designed for use with decking materials, such as wood or composite decking. They have a special coating to prevent corrosion, and they often have a special thread design that allows them to grip the decking material securely.

Screw Materials and Coatings
When it comes to screws, the materials and coatings used can make a big difference in their performance and durability. Understanding the different options available can help you choose the right screws for your project. Here are some of the most common materials and coatings used for screws.
Metal Screws
Metal screws are some of the most commonly used screws. They are typically made from steel or brass, and can be coated with a variety of materials to improve their performance. Metal screws are strong and durable, making them a good choice for many different applications.
Stainless Steel
Stainless steel screws are a popular choice for outdoor and marine applications, as they are resistant to rust and corrosion. They are also strong and durable, making them a good choice for heavy-duty applications. However, stainless steel screws can be more expensive than other types of screws.
Brass Screws
Brass screws are often used for decorative applications, as they have a bright, shiny finish. They are also resistant to rust and corrosion, making them a good choice for outdoor applications. However, brass screws are not as strong as steel screws, so they may not be suitable for heavy-duty applications.
Coated Screws
Coated screws are designed to provide extra protection against rust and corrosion. Common coatings include zinc, which is relatively inexpensive and provides good rust protection, and hot-dip galvanizing, which provides even better rust protection. Other coatings include black oxide, which provides a decorative finish, and ceramic coatings, which provide excellent corrosion resistance.
At Fastening Specialists, we offer a wide range of screws in different materials and coatings to suit your needs. As a trusted wholesale distributor for over 65 years, we have the expertise and knowledge to help you choose the right screws for your project.

Understanding Screw Sizes
When it comes to screws, understanding the different sizes available is essential for any project. Screw sizes are usually listed in metric (millimeters) or imperial (inches) units. The numbers on screws (#6, #8, etc.) indicate the diameter, with higher numbers representing larger diameters.
Diameter and Length
The diameter of a screw is measured across the widest part of the thread, while the length is measured from the tip of the screw to the end of the shank. It’s important to choose the right diameter and length for your project to ensure a secure fit.
Different types of screws have different length measurements. For example, machine screws are measured from the underhead bearing surface to the extreme end of the bolt, while wood screws are measured from the tip to the end of the shank.
Thread Pitch
The thread pitch is the distance between the threads on a screw. It’s important to choose the right thread pitch to ensure a secure fit and avoid damaging the material you’re screwing into. The thread pitch is usually measured in threads per inch (TPI) for imperial screws and millimeters for metric screws.
When choosing a screw, it’s important to consider the load-bearing capacity and application. For example, if you’re screwing into softwood, you’ll need a screw with a wider thread pitch to avoid splitting the wood.

Screw Drive Types and Head Styles
When it comes to screws, there are two main components that you need to consider: the drive type and the head style. The drive type refers to the tool you use to install or remove the screw, while the head style refers to the shape of the head itself. In this section, we’ll go over some of the most common screw drive types and head styles.
Slotted and Phillips
Slotted screws are perhaps the most basic type of screw. They have a single straight slot cut into the head, and you use a flat-bladed screwdriver to install or remove them. Phillips screws, on the other hand, have a cross-shaped slot in the head, and you use a Phillips-head screwdriver to install or remove them. Phillips screws are often used in mass-produced products because they are easier to automate than slotted screws.
Hex and Allen
Hex screws, also known as hex bolts, have a hexagonal head that requires a wrench or socket to install or remove. Hex screws are often used in construction and automotive applications because they are strong and easy to use. Allen screws, also known as socket head screws, have a hexagonal socket in the head that requires an Allen wrench to install or remove. Allen screws are often used in machinery and electronics because they are small and can be installed in tight spaces.
Torx and Star
Torx screws, also known as star screws, have a six-pointed star-shaped socket in the head that requires a Torx screwdriver to install or remove. Torx screws are often used in electronics and automotive applications because they are less likely to strip than other types of screws. Star screws, also known as security screws, have a star-shaped head that requires a special driver to install or remove. Star screws are often used in applications where tampering or theft is a concern.
No matter what type of screw you need, Fastening Specialists has you covered. As a trusted wholesale distributor for over 65 years, we are specialists in this field.

Selecting the Right Screw for Your Project
When it comes to selecting the right screw for your project, there are several factors to consider. In this section, we will explore the different types of screws available and how to choose the best one for your project.
Interior vs. Exterior
The first consideration when selecting a screw is whether it will be used indoors or outdoors. Exterior screws need to be able to withstand exposure to the elements, so they must be made from materials that are resistant to rust and corrosion. For example, stainless steel screws are an excellent choice for outdoor projects because they are highly resistant to rust and corrosion. On the other hand, interior screws do not need to be as durable, so they can be made from less expensive materials like zinc-plated steel.
Load and Force Considerations
Another important consideration when selecting a screw is the amount of load and force that it will need to bear. For example, if you are building a deck or installing composite decking, you will need to use screws that are specifically designed for this purpose. These screws are typically made from hardened steel and have a special coating that helps them resist corrosion.
If you are attaching your project to metal studs, you will need to use screws that are specifically designed for this purpose. These screws are typically self-tapping and have a sharp point that helps them penetrate the metal.
Specialty Screws
In addition to standard screws, there are also specialty screws that are designed for specific applications. For example, anchor screws are used to attach objects to concrete or masonry, while tamper-proof screws are used to prevent unauthorized removal or tampering. Lag bolts and carriage bolts are used for heavy-duty applications, such as attaching large pieces of lumber together.
At Fastening Specialists, we offer a wide range of screws and fasteners for all types of projects. Our expert team can help you select the right screw for your project based on your specific needs and requirements.
