What is a screwdriver?

At its core, a screwdriver is a handheld tool designed for turning screws. Its primary purpose is to apply torque to screws, facilitating the insertion or removal of these fasteners. The simplicity of its design belies its significance, making it a fundamental tool in construction, carpentry, electronics, and various other industries.

History of screwdriver:

The history of the screwdriver dates back to the 15th century, with its earliest iterations resembling flat-bladed tools. The concept of the modern screwdriver took shape in the 18th century, coinciding with the widespread use of screws. The evolution of the screwdriver continued, leading to the development of various types to accommodate different screw heads.

Types of screwdriver:

  • Flathead Screwdriver: The Flathead Screwdriver, also known as the Slotted Screwdriver, features a flat, straight blade, making it suitable for screws with a single, straight slot. It is a basic and widely used tool for various applications, but it may be more prone to slipping compared to other screwdriver types.
  • Phillips Screwdriver: The Phillips Screwdriver has a cross-shaped tip designed to engage with Phillips-head screws, featuring a cruciform pattern with rounded edges. This design prevents the driver from slipping out and provides improved torque, making it a common choice for electronic devices, appliances, and machinery.
  • Torx Screwdriver: The Torx Screwdriver has a star-shaped tip, specifically designed for Torx screws, which have a corresponding hexalobular drive. This type of screwdriver is commonly used in automotive and electronics applications due to its ability to distribute torque evenly and resist cam-out, providing a more secure grip on the screw.
  • Hex Screwdriver (Allen Wrench): The Hex Screwdriver, also known as an Allen Wrench, features a hexagonal-shaped tip, suitable for hex socket screws. Typically L-shaped or T-shaped, it is widely used in assembling furniture, machinery, and various mechanical applications where hexagonal fasteners are common.
  • Robertson Screwdriver: The Robertson Screwdriver, also known as a square drive or Scrulox, has a square-shaped tip. Popular in Canada, it offers a secure and efficient grip, reducing the likelihood of slipping and making it commonly used in woodworking and construction projects.
  • ¬†Pozidriv Screwdriver: The Pozidriv Screwdriver has a cross-shaped tip similar to Phillips but with additional cross slots. This design enhances torque transmission and reduces the risk of cam-out, making it suitable for applications where high torque and precision are required, such as in automotive and engineering.
  • Ratchet Screwdriver: For enhanced efficiency, the ratchet screwdriver employs a mechanism that allows continuous turning in one direction without lifting the tool. This proves invaluable in tight spaces where a traditional screwdriver may struggle to maneuver.
  • Tri-wing Screwdriver: The Tri-wing Screwdriver has a triangular-shaped tip, designed to fit screws with three wings or slots. Commonly used in electronics, particularly in video game consoles, it provides a specialized tool for tamper-resistant screws and helps deter unauthorized access to electronic devices.
  • Spanner Screwdriver (Security Screwdriver): The Spanner Screwdriver, also known as a Security Screwdriver, is designed for screws with two small round pins in the center. This specialized tool is often used in tamper-resistant applications where conventional screwdrivers are ineffective, providing an added level of security against unauthorized access.
  • Clutch Head Screwdriver: The Clutch Head Screwdriver features a concave tip with a flat center, designed for screws with a unique clutch head configuration. This type of screwdriver is often used in security screws and certain older automotive applications, offering a specialized tool for specific fastening systems.
  • Y-type Screwdriver: The Y-type Screwdriver has a Y-shaped tip, making it suitable for screws with a corresponding Y-shaped groove. Commonly used in electronics, this specialized screwdriver provides a unique tool for specific applications, offering precision and engagement with Y-type screws.
  • Offset Screwdriver: The Offset Screwdriver has a handle set at an angle to the blade, allowing for easier access to screws in tight or awkward spaces. This design provides a practical solution for situations where a straight-line approach with a standard screwdriver may be challenging.
  • Precision Screwdriver: The Precision Screwdriver is a smaller-sized tool designed for delicate and precise work, often in electronics and small appliances. Featuring a slender shaft and a variety of interchangeable tips, it allows users to handle tiny screws with accuracy and control.
  • Torque Screwdriver: The Torque Screwdriver is designed for precise control of torque when tightening screws. It ensures that screws are tightened to specific torque specifications, making it a valuable tool in applications where over-tightening or under-tightening could have critical consequences, such as in electronics or precision machinery.
  • Insulated Screwdriver: The Insulated Screwdriver is designed for electrical work, featuring a handle that provides insulation to protect against electric shock. This safety feature makes it suitable for tasks involving live electrical components, reducing the risk of electrical conductivity through the tool to the person using it.

How to use screwdriver:

Using a screwdriver is a straightforward process, but it’s important to follow the correct steps to ensure safe and effective use. Here’s a general guide on how to use a screwdriver:


  • Screwdriver
  • Screw
  • Object or material you’re fastening


  • Select the Right Screwdriver: Choose a screwdriver that matches the type and size of the screw you’re working with. Different screw heads require specific screwdrivers (e.g., flathead, Phillips, Torx).
  • Inspect the Screw and Screwdriver: Ensure that both the screw and the screwdriver are in good condition. A damaged screw or screwdriver may result in difficulty or inability to drive the screw.
  • Hold the Screwdriver Properly: Grip the screwdriver handle near the base with your dominant hand, and place your other hand on top for stability. Hold the screwdriver perpendicular to the screw.
  • Align the Screwdriver with the Screw: Position the screwdriver’s tip into the screw head slot or recess. Make sure the screwdriver is properly seated to avoid slipping and damaging the screw or the surrounding material.
  • Apply Steady Pressure: Apply a downward force on the screwdriver to maintain good contact between the screwdriver and the screw. This helps prevent the screwdriver from slipping out.
  • Turn the Screwdriver Clockwise (Tightening) or Counterclockwise (Loosening): If you’re tightening the screw, turn the screwdriver clockwise. If you’re loosening the screw, turn the screwdriver counterclockwise. Use a steady, controlled motion.
  • Use Adequate Force: Apply enough force to turn the screw, but avoid excessive force that could damage the screw or the screwdriver.
  • Complete the Task: Continue turning the screwdriver until the screw is fully driven into the material or until it is sufficiently loosened.
  • Inspect the Fastening: Ensure that the screw is securely in place. If the screw is not fully tightened or is too loose, make any necessary adjustments.
