Screwdrivers Buying Guide

Most people own at least one screwdriver and have it readily on hand for frequent use, but many folks do not realise that there is a wide array of screwdrivers available to get a job done effectively and efficiently. Screwdrivers come in a variety of sizes and shapes. Having the correct screwdriver for the job is extremely important because a tool that does not fit the screw's head will strip away the head and cause irreversible damage to the screw.


Types of Screwdrivers

A screwdriver consists of a metal rod. The handle that the user grips is on one end of the rod, and the screwdriver's head is on the other end. The type of head distinguishes the type of screwdriver.


The most common screwdriver around the world is the slotted screwdriver. Slot-head screws have been used for centuries, but their popularity is decreasing because they are difficult to snugly tighten without the screwdriver's head slipping out of the slot on the screw's head. They come in a wide array of sizes from 2.4 mm to 13 mm.


The Phillips head screwdriver is the second most popular screwdriver around the world. It features a cross-shaped head that readily fits into the screw's cross-engraved head. The cross formation helps prevent the screwdriver's head from slipping out of the screw. The head is also tapered to a 57-degree angle to help it fit tightly into the screw. Phillips screwdrivers come in a variety of sizes such as Phillips #1, #2, and #3. The most common and widely available Phillips size is the #2 screwdriver.


The Pozidriv screwdriver is widely available in Europe and Australia. It resembles a Phillips screwdriver but features four more contact points to help it fit snugly into the screw. A Pozidriv screwdriver rarely slips out of the screw when being twisted.The Pozidriv screwdriver is available in sizes #1, #2, and #3.

Square Recess

A square recess screwdriver has a square head that slides easily into the depression of a square screw or bit. It does not easily slip out, and it does not mark or disfigure the screw. The most common size of square recessed screwdrivers are the Square #2 and #3.


A torx screwdriver is shaped like a six-pointed star. They can handle a great deal of torque without slipping out of the screw. Their increased ability to take torque means that the screw can be quickly and effectively tightened. The most common sizes of a torx screwdriver are the T1 to T100.


The hex screwdriver has a head that is shaped like a hexagram. They can be used on screws that usually require an Allen wrench to loosen or tighten them. Their hex shape helps create a strong connection for easy tightening and loosening.


Although quite rare, spanner screwdrivers are also called "snake eyes" or "notched" screwdrivers. They are used on tamper-resistant screws. The most common sizes of spanner screwdrivers are the #4, #6, #8, #10, #12, and #14.

Tri Wing

The tri wing screwdriver is very rare and known for its tamper resistance. It is available in sizes #1, #2, and #3.

Power Screwdriver

Power screwdrivers use electric or battery power to operate with ease. The power gives the screwdriver the ability to operate quickly and effectively without wearing out the user. There is very little doubt that a power screwdriver drives a screw into any surface tightly and quickly. It also works in reverse. The user usually interchanges bit types as needed to get the job done. Most power screwdrivers have the ability to take numerous bit types and sizes. The user simply loosens the screwdriver's chuck and slips the type of bit he needs into the driver.

Ratchet Screwdriver

A ratchet screwdriver is a manual screwdriver that does not rely on a power source to function. It is designed to work utilising a built-in ratchet system to help minimise the user's wrist motions. The ratchet function allows the user to quickly tighten or loosen a screw without exhausting physical force. A ratchet screwdriver is easy to use, does not stress the user's arm or wrist, and both tightens and loosens screws quickly.

Offset or Right Angle Screwdriver

An offset screwdriver, also called a right angle screwdriver, is a manual screwdriver that is shaped like a Z or an L. Its unique design and shape lets the user gain access to difficult-to-reach places. Offset or right angle screwdrivers are usually quite large and commonly used when working on autos or trucks.



As more automotive and general household item designs become complicated, it becomes even more important for a homeowner to have a wide array of screwdriver types and sizes to get the job done. Buyers can turn to eBay sellers for the tools they need.
