What The Types Of Common Screws?

There are many different types of screws, each designed for specific purposes and applications. Screws come in various shapes, sizes, and materials, and they have different thread patterns and heads. As a professional fastener supplier, Xinchi Fastener Company is glad to share some common types of screws.

Wood Screws: These have coarse threads and are designed for use in wood. They often have a tapered point to make it easier to insert them into the wood without the need for a pilot hole.

Machine Screws: These have finer threads and are typically used with nuts or in threaded holes. They come in various sizes and can be used in metal, plastic, or other materials.

Sheet Metal Screws: These screws have sharp, pointed threads and are used for fastening metal sheets, thin plastic, or other similar materials.

Self-Tapping Screws: These have a special thread design that allows them to create their own threads as they are driven into the material. They are often used in metal or plastic.

Drywall Screws: These have a bugle-shaped head and fine threads, designed specifically for attaching drywall to wood or metal studs.

Concrete Screws: Also known as masonry screws or anchor screws, these are designed for use in concrete, brick, or block walls. They often have special features like fluted threads or a special drill bit for installation.

Lag Screws: These are heavy-duty wood screws with a hexagonal head. They are often used for securing heavy objects to wood, like attaching a wooden beam to a post.

Socket Head Cap Screws: These screws have a cylindrical head with a recessed hex socket, and they are often used in machinery and equipment.

Hex Bolts: Similar to socket head cap screws, but they have a nut that fits onto the threaded shaft. They are used when a secure connection is needed.

Phillips Head Screws: These have a cross-shaped recess in the head and are one of the most common types of screws.

Flat Head Screws: These have a flat top surface and are often used when a screw head needs to sit flush with the material’s surface.

Round Head Screws: These have a rounded top surface and are used for decorative or low-profile applications.

Pan Head Screws: These have a slightly rounded, low-profile head with a flat underside. They are often used in electrical and electronic applications.

Torx Screws: These have a star-shaped recess in the head and provide better torque transmission and resistance to cam-out compared to Phillips screws.

Security Screws: These screws have unique drive designs, such as pin-in-torx or snake eye, to deter tampering or unauthorized removal.

One-Way Screws: These are designed to be installed easily but difficult to remove, often used for security purposes.

Thumb Screws: These have a knurled or winged head, allowing for hand tightening without the need for tools.

Shoulder Screws: Also known as shoulder bolts, these have a cylindrical shoulder between the head and the threaded portion. They are often used in precision machinery.

Threaded Rods: These are long, straight rods with threads along their entire length. They are used for creating custom-length fasteners or for structural purposes.

Eye Bolts: These have a looped head and are used for attaching cables, ropes, or hooks.

These are just some of the many types of screws available, and the choice of screw depends on the specific requirements of the project or application.
