Types of Screwdrivers: The Ultimate Guide to Heads, Sizes, and Uses
A screwdriver is a fundamental hand tool used to install or remove screws by providing rotational torque. Whether you are wondering what a screwdriver looks like or need to define a Phillips screwdriver, this guide covers everything from common screwdriver types to specialized triangle bit screws.
1. What Does a Screwdriver Look Like?
A standard manual screwdriver consists of a handle for grip, a steel shaft (shank), and a specific tip. Understanding the names of screwdriver heads is essential to avoid damaging your hardware.
Common Screwdriver Varieties
Slotted (Flat Head): The traditional single-blade tip for basic woodworking.
Phillips: The cross-shaped (+) industry standard designed to prevent over-tightening.
Hex Screwdriver (Allen Key): Used for hexagonal sockets in furniture and bicycles.
