They come in various sizes, lengths, and thread types to accommodate different materials and applications. Screws may have different head styles, such as flat, Phillips, or hex, to suit specific tools for tightening.A screw is a versatile, threaded fastener designed to join materials by cutting its own threads into a surface or mating with a pre-threaded hole. Unlike bolts, screws typically do not require a nut and provide strong, reliable fastening in wood, metal, plastic, and composite materials. Available in various head types (Phillips, slotted, hex, Torx) and drive styles, screws are widely used in construction, automotive, electronics, furniture, and machinery applications. Made from steel, stainless steel, brass, or titanium, screws offer excellent durability and corrosion resistance.

Some screws are coated for corrosion resistance or designed for specific purposes, like wood, metal, or drywall.A screw is a helical-threaded fastener designed to join or secure materials by cutting its own threads into a surface or fitting into a pre-threaded hole. Unlike bolts, screws generally do not require a nut, making them a self-sufficient fastening solution. They are widely used in construction, woodworking, metalworking, automotive, electronics, furniture, and industrial machinery due to their versatility, strength, and ease of installation.Screws are one of the most essential and versatile fastening solutions, offering strength, ease of use, and adaptability across multiple industries. Their wide range of types, materials, and coatings ensures optimal performance in different applications, making them indispensable in construction, manufacturing, and everyday use.
