Screwdrivers are essential hand tools used for driving and removing screws. They come in various types and sizes, each designed to accommodate different types of screw heads and specific applications. Here are some common types of screwdrivers and their uses:

Flathead Screwdriver: Also known as a slotted screwdriver, this is one of the most basic types. It has a flat, straight blade that fits into a single slot on a flathead screw. Flathead screwdrivers are widely used in many applications, from household tasks to electronics repair.

Phillips Screwdriver: The Phillips screwdriver has a cross-shaped tip designed to fit into the corresponding cross-shaped recess on a Phillips screw head. It’s commonly used in woodworking, construction, and electronics.

Pozidriv Screwdriver: Similar to the Phillips screwdriver, the Pozidriv screwdriver has a cross-shaped tip but with additional smaller cross lines in each quadrant. It provides better torque transfer and is often used in applications requiring higher torque, such as automotive and industrial settings.

Torx Screwdriver: Torx screwdrivers are used for Torx screws, which have a star-shaped recess. They provide a secure grip and are commonly used in electronics, automotive, and machinery.

Hex Screwdriver (Allen Key): This type of screwdriver has a hexagonal (six-sided) tip, often referred to as an Allen key. It’s used for driving hex screws commonly found in furniture assembly, machinery, and bicycles.

Square Screwdriver (Robertson Screwdriver): The square screwdriver is designed for square-headed screws, also known as Robertson screws. These screws are prevalent in construction and woodworking, especially in North America.

Tri-Wing Screwdriver: Tri-Wing screwdrivers are used for screws with three slotted wings. They are often found in electronics and appliances.

Spanner Screwdriver (Snake Eye): Spanner screwdrivers, also known as snake eye screwdrivers, have two small pins that fit into corresponding holes on spanner screws. These screws are used in security applications to prevent tampering.

Clutch Screwdriver: Clutch screwdrivers are used for screws with a clutch head that has a circular groove. They are often found in electrical applications and some security screws.

One-Way Screwdriver: One-way screwdrivers are used with one-way screws, which can be installed but not easily removed. They are often used in security and anti-tamper applications.
