Common Types of Screws
There are many different types of screws that are each used for different applications. Each screw has its own type of thread, head style, drive style, point type, material, and sometimes plating. Some of the most common types of screws are listed below. If you have any additional questions or are looking for a different type of screw, reach out to our knowledgeable sales team with any questions email@example.com.
Used to fasten metal to metal or metal to plastic.
These screws are driven into a tapped hole or used with a nut since they have a blunt flat tip. These come in many different head types (IE: flat, pan, round, oval). A screwdriver with the appropriate bit (IE: Phillips, Torx, Square Socket, Slot, etc.) is used to tighten it. Machine screws are frequently used due to their smaller size. See here for sizes available.
Sheet Metal Screws
Used to attach metal to metal or metal to other materials.
Sheet metal screws (SMS) are frequently called self tapping screws which have a sharp point allowing them to cut through various materials such as metal, plastic, wood, etc. These are fully threaded and available in types A, B or AB dependent on size. They come in a variety of head and drive types. See options available here.
Self Drilling Screws
Used with metal or wood, etc.
Great for quick drilling jobs since the threads tap the hole while being installed. There’s no need for a pre-drilled pilot hole due to the sharp cutting point. See our self-drilling screws available here.
Hex Cap Screws
Used to attach wood to wood or metal to wood.
These have a flat hexagonal head which can be tightened with a wrench or a socket. They can be driven into a tapped hole or used with a nut since they have a blunt flat tip. The fully threaded versions are called tap bolts. There are lots of options for sizes and materials available here.
Wood Screws, etc.
Used to join wood to wood.
Wood screws have a smooth shank at the top with a tapered pointed end. Pilot holes are sometimes required. These are most popular with a flat head so they sit flush in the wood. They’re also available in other head styles such as pan, round, or oval if required. See options here.
Used for heavier duty jobs.
Lag screws have a flat hexagonal head and have a pointed tip. These come in larger diameters and lengths than most other screws. Most commonly they’re galvanized, zinc plated, or stainless steel which are weather-resistant for outdoor use. Great for long-lasting holds. We have lots of options available here.
