However, with so many different types of screws available, it can be difficult to choose the right one for the job. In this article, we will provide a comprehensive guide to the different types of screws and their uses, so you can make an informed decision when selecting screws for your next project.

Sheet Metal Screws

Sheet metal screws, also known as self-tapping screws, are designed to tap their own threads into thin metal sheets and other lightweight materials. They have sharp threads that cut into the material, making them ideal for applications where a strong, permanent connection is required.

Wood Screws

Wood screws are specially designed for fastening wood and other materials that are soft and porous. They have a tapered shank and a sharp thread that cuts into the wood, allowing for a tight and secure connection. Wood screws are commonly used in furniture making, cabinetry, and woodworking projects.

Machine Screws

Machine screws are small screws used to fasten metal parts together. They typically have a uniform diameter and a thread that runs the entire length of the screw. Machine screws are commonly used in electronic devices, appliances, and other machinery. Often used in combination with nuts to tighten connection.

Lag Screws

Lag screws, also known as lag bolts, are large, heavy-duty screws used for fastening wood and other heavy materials. They have a square or hexagonal head and a threaded shaft that is driven into the material using a wrench or pliers. Lag screws are commonly used in construction and carpentry applications where a strong, permanent connection is required.

Self-Drilling Screws

Self-drilling screws, also known as TEK screws, are screws with a unique design that allows them to drill into the material and create their own threads without the need for a pilot hole. This makes them ideal for applications where a fast, secure connection is required and a pilot hole cannot be drilled.

Drywall Screws

Drywall screws are specifically designed for fastening drywall to wood or metal studs. They have a sharp point that easily penetrates the drywall and a coarse thread that provides a strong grip. Drywall screws are commonly used in construction and DIY projects for hanging drywall and other lightweight materials.

Concrete Screws

Concrete screws, also known as masonry screws, are designed to be used in concrete and other masonry materials. They have a carbide tip that allows them to easily penetrate the material and a thread that provides a strong grip. Concrete screws are commonly used in construction for fastening objects to concrete walls and floors.

Deck Screws

Deck screws are specifically designed for fastening deck boards and other outdoor lumber. They have a corrosion-resistant coating that protects them from the elements, making them ideal for outdoor use. Deck screws have a sharp point that easily penetrates the wood and a thread that provides a tight, secure connection.

Thumb Screws

Thumb screws are large, easy-to-use screws that are designed to be tightened and loosened by hand, without the need for a screwdriver or wrench. They have a large head that is easy to grip, making them ideal for applications where frequent access is required.

Dowel Screws and Hanger Bolts

Dowel screws are headless double ended fasteners with two tapered lag screw ends. Often used in woodworking and furniture manufacturing to create a hidden joint.

Hanger Bolts are half machine screw and half lag screw. Like Dowel Screws, Hanger Bolt are double ended fasteners with a machine screw thread at one end and a tapered wood screw thread at the other. They are designed to be screwed into wood and on the other end can secure objects by threading on a nut. Also known as Table Leg Bolts, Hanger Bolts are commonly used in the woodworking and furniture industries.

Socket Cap Screws

Socket Cap Screws are a family of fasteners that are amongst the most common types of fasteners for machinery assembly work. So called because of an internal drive recess built into the head, usually hexagonal in shape.

Thread Cutting Screws

Thread Cutting Screws are a type of self-tapping screw designed to tap its own threads as it penetrates a pre-drilled pilot hole. Manufactured with specialized screw points – referred to as “Types” (Type 1, Type 23, Type 25 and Type F) – designed to physically remove material from the substrate to form the tapped thread path.

Thread Rolling Screws

Contrary to Thread Cutting Screws, Thread Rolling Screws are designed to deform (instead of eject) the material that they are screwed into in order to form a thread in an untapped hole. There are different designs of Thread Rolling Screws depending on whether they are meant to be screwed into metals or plastics.

We will get into more depth on each of these types of screws and varieties within each category at a later date, but for more information and availability you can always contact us or visit our store page for screws.
