Fastener screws are essential components in virtually every industry—from construction and automotive to electronics and furniture manufacturing. Choosing the right type of screw is critical to ensuring a secure, long-lasting assembly. Each screw type is designed with specific applications in mind, offering varying head styles, thread patterns, drive types, and materials.
Common Types of Fastener Screws:
-
Machine Screws
Used to fasten components in machinery, electronics, and appliances, machine screws are typically paired with tapped holes or nuts. They come in a variety of head types like flat, pan, round, and fillister, and drive styles such as Phillips, slotted, and Torx. -
Self-Tapping Screws
These screws tap their own mating thread into the material—ideal for sheet metal, plastics, or wood. They’re widely used in construction, HVAC, and automotive bodywork. -
Wood Screws
Specifically designed for woodworking, these screws have coarse threads for strong holding power and come with flat or oval heads for a flush finish. -
Sheet Metal Screws
Built for fastening thin metal materials, they often feature sharp threads and pointed tips for quick penetration. Available in both self-drilling and standard styles. -
Socket Head Cap Screws
These are high-strength fasteners with internal hex drives, often used in precision assemblies like industrial equipment, robotics, and automotive systems. -
Set Screws
Set screws are headless fasteners used to secure components like gears or pulleys to shafts. Commonly used in rotational assemblies.
Specifications & Selection:
Fastener screws vary by material (steel, stainless, brass), thread pitch (fine, coarse), strength grades (e.g., 8.8, 10.9, 18-8), and finishes (zinc, black oxide, phosphate).
