Types of Screws

Myriad types of screws have been invented to perform specific tasks.

  • cap screw has a convex head, usually hexagonal, designed to be driven by a spanner or wrench.
  • The wood screw has a tapered shaft allowing it to penetrate the undrilled wood.
  • The machine screw has a cylindrical shaft and fits into a nut or a tapped hole, a small bolt.
  • The self-tapping screw has a cylindrical shaft and a sharp thread that cuts its own hole, often used in sheet metal or plastic.
  • drywall screw is a specialized self-tapping screw with a cylindrical shaft that has proved to have uses far beyond its original application.
  • The set screw has no head at all and is designed to be inserted flush with or below the surface of the work piece.
  • The double-ended screw is a wood-screw with two pointed ends and no head. It is used for making hidden joints between two pieces of wood.

Shapes of Screw Head

  • Pan head: disc with a chamfered outer edge
  • Cheesehead: disc with a cylindrical outer edge
  • Countersunk: conical, with flat outer face and tapering inner face allowing it to sink into the material, very common for wood screws
  • Button or dome head screw: flat inner face and hemispherical outer face
  • Mirror screw head: countersunk head with a tapped hole to receive a separate screw-in chrome-plated cover; used for attaching mirrors

Types of Screw Drive

Slot head screws are driven by a flat-bladed screwdriver.
Cross-head or Phillips screws have an X-shaped slot and are driven by a cross-head screwdriver, designed originally in the 1930s for use with mechanical screwing machines, intentionally made so the driver will ride out, or cam out, under strain to prevent over-tightening.
The Pozidriv is an improved Phillips head screw, and it has its own screwdriver, similar to cross-head but with better resistance to slipping, or cam-out.
Hexagonal or hex screw heads have a hexagonal hole and are driven by a hexagonal wrench, sometimes called an Allen key or a power tool with a hexagonal bit.
Robertson drive head screws have a square hole and are driven by a special power-tool bit or screwdriver (this is a low-cost version of the hex head for domestic use).
Torx head screws have a splined socket and receive a driver with a splined shaft.
Tamper-proof Torx’s drive sockets have a projection to prevent a standard Torx driver being inserted.
Tri-Wing screws were used by Nintendo on its Gameboys, and don’t have a driver associated with them, which has discouraged even minor home repairs to the units.
