Screws – Types, Uses & Key Features

Screws are essential metal fasteners used to securely join wood, metal, plastic, and composite materials. Featuring a helical thread around a central shank, screws are driven by turning the head with a screwdriver or drill, converting rotational force into strong holding power. Many screws cut their own thread, making installation quick and reliable without the need for a nut.

Available in a wide range of sizes, materials, head styles, and thread types, screws are suitable for everything from DIY projects to professional construction and engineering applications.

Screw Components Explained

• Head – Designed to accept a driving tool such as Phillips, Pozidriv, Torx, hex, or slotted drivers.

• Threaded Shank – Provides grip and pull-out resistance within the material.

• Thread Type –

  • Coarse threads for soft materials like timber and plasterboard

  • Fine threads for harder materials such as metal

• Tip – Pointed, flat, self-tapping, or self-drilling tips for faster penetration and reduced splitting.

Common Screw Types

• Wood Screws – Ideal for softwood and hardwood, offering strong grip and clean fixing.

• Drywall Screws – Corrosion-resistant fasteners for securing plasterboard to timber or metal studs.

• Self-Tapping & Self-Drilling Screws – Cut or drill their own threads, perfect for metal sheets and panels.

• Machine Screws – Used with pre-tapped holes or nuts in mechanical and electrical applications.

• Deck Screws – Weather-resistant screws designed for outdoor decking and fencing.

Screws vs Bolts

Unlike bolts, which require a nut for fastening, screws are tightened by turning the head and typically form their own thread or engage with a pre-threaded hole making them faster and more versatile for many applications.
