What Are Screws?

Screws are threaded fasteners that are used to hold materials together. They come in various shapes, sizes, and materials, and are categorized according to their usage, including wood, metal, and specialized tasks. Whether you’re a supplier of screws in Qatar or a exporter of screws in the USA, understanding the types of screws and their applications is crucial for choosing the right hardware for your needs.

II. Types of Screws

1. Wood Screw: These screws are specifically designed for wood, featuring sharp threads that provide a tight grip. They are used in carpentry and furniture assembly projects.
2. Thread Cutting Screw: Thread cutting screws are used to create threads in materials that are not pre-threaded. They are ideal for softer materials like wood and plastic.
3. Mushroom Head Screw: With a low-profile, rounded head, mushroom head screws are commonly used for applications requiring a smooth finish.
4. Thread Forming Screw: Thread forming screws are used in applications where the material does not require a tapped hole. They create threads as they are driven into the material.
5. Set Screw: These screws are designed to secure an object within or against another object, typically without a head, using only the threaded portion.
6. Hex Socket Cap Screw: Hex socket cap screws are commonly used in machinery, offering high torque capabilities due to their hexagonal drive.
7. Pan Head Screw: Featuring a rounded head, pan head screws are often used in electrical applications and for fastening sheet metal.
8. Self-Drilling Screw: These screws are ideal for metalwork, as they feature a drill point that eliminates the need for pre-drilling.
9. T Head Screw: T-head screws are used when a flush, non-rotating connection is needed, often in industrial applications.
10. Square Screw: Square screws are similar to slotted screws but offer better torque. These screws are often used in applications requiring more security.

16. Oval Head Screw: Oval head screws offer an aesthetic, raised appearance, commonly used in furniture and interior applications.
17. Fillister Head Screw: Fillister head screws are similar to pan head screws but have a deeper, cylindrical recess that provides a better grip.
18. Hex Cap Screw: Hex cap screws are standard fasteners used across industries, offering durability and high-strength fastening.

21. Flange Head Screw: Flange head screws feature a wider surface area beneath the head, providing additional grip and making them ideal for materials that are soft or thin.
22. Knurled Head Screw: These screws feature a textured, ridged head that provides a better grip for manual tightening or loosening.
23. Mating Screw: Mating screws are used to connect two components together in mechanical and electrical applications.
24. Button Head Cap Screw: With a rounded head, button head cap screws are perfect for applications where a low-profile fastener is required.
25. Countersunk Head Screw: Countersunk screws sit flush with the surface of the material when fully installed, providing a clean and professional look.

Materials Used in Screw Manufacturing

The material of the screw plays a significant role in its strength, durability, and corrosion resistance. Common materials include stainless steel, carbon steel, and brass, each chosen depending on the application. For example, leading manufacturers of screws in the USA may also manufacture screws designed to meet specific standards for pressure and durability, ensuring the components perform well under extreme conditions.
