What Are The Types Of Screws?

Screws are essential fasteners used in various applications, from construction and woodworking to electronics and machinery. They come in numerous types, each designed for specific purposes.

As a reliable fastener supplier in China, Xinchi Fastener Co., Ltd, which has an ISO9001-accredited factory, is glad to introduce a brief overview of some common types of screws.

Wood Screws: Designed to join pieces of wood. They have a sharp point for easy penetration and a coarse thread to grip the wood securely.

Machine Screws: Used to fasten metal parts together. They have a uniform thread diameter and are used with nuts or tapped holes.

Sheet Metal Screws: Similar to wood screws, but designed for connecting thinner metal parts. They often have a sharp point and threads that cut into the metal.

Self-tapping (or Self-drilling) Screws: Have a pointed or fluted tip that allows them to create their own thread path as they are driven into the material. This eliminates the need for a pre-drilled hole.

Drywall Screws: Specifically designed for hanging drywall panels. They have a bugle head that sits flush against the drywall and a sharp point for easy insertion.

Deck Screws: Similar to wood screws but typically made from weather-resistant materials to withstand outdoor elements. They often have a coated surface to prevent rust.

Concrete Screws: Designed to fasten materials to concrete. They are made from hardened steel and have a high-low thread design for better grip in concrete.

Security Screws: Also known as tamper-resistant screws, they have a unique head design that requires a special tool for installation or removal, providing added security.

Hex Screws: Characterized by a hexagonal head, these screws are driven with a wrench or socket tool. They offer a stronger tool engagement, which is useful for heavy-duty applications.

Torx Screws: Feature a six-point star-shaped pattern on the head, providing a better grip for the driver bit and reducing the chance of cam-out (slipping).

This list is not exhaustive, as there are many specialized screws designed for specific industries or applications. The choice of screw depends on the materials being fastened, the environmental conditions, and the required strength of the joint.
