What are Screwdrivers?

Screwdrivers are handheld tools used for driving or removing screws. They consist of a handle and a shaft with a tip, known as the “bit,” which corresponds to the head of the screw. By applying torque to the handle, screwdrivers allow for the turning motion needed to tighten or loosen screws.

Screwdrivers come in various types, including:

  1. Flathead/Slotted Screwdrivers: These have a flat, single-slot tip that matches slotted screws. They are commonly used for simple and older types of screws.
  2. Phillips Screwdrivers: Phillips screwdrivers have a cross-shaped tip designed for use with Phillips screws, which have a corresponding cross-shaped recess. They are widely used in many applications.
  3. Pozidriv Screwdrivers: Pozidriv screwdrivers are similar to Phillips screwdrivers but have additional smaller cross-shaped indents within each of the four main lobes. They provide better torque transfer and are commonly used in construction and woodworking.
  4. Torx Screwdrivers: Torx screwdrivers have a star-shaped tip with six points. They are used with Torx screws, which offer better resistance to cam-out (slippage) and are commonly found in electronics, automotive applications, and appliances.
  5. Hex Screwdrivers: Hex screwdrivers have a hexagonal tip that matches hex screws and bolts. They are commonly used in furniture assembly, machinery, and construction.
  6. Square/Robertson Screwdrivers: Square screwdrivers have a square-shaped tip designed for use with Robertson screws, which have a corresponding square recess. They provide good torque transfer and are popular in woodworking and construction in North America.

Screwdrivers are available in various sizes and can be made with different handle materials such as plastic, rubber, or cushioned grips for comfort and improved grip. Additionally, there are powered screwdrivers that use electric motors or batteries to automate the driving process.
