How to Use a Screwdriver Properly


A screwdriver is a hand tool used for turning screws. You can find both powered and manual versions. A screwdriver typically has a shaft and handle, and the tip is placed into the head of the screw before turning the handle. It is essential for completing tasks such as re-assembling furniture or removing stubborn hardware. Depending on the type, it may be a phillips, slotted, or tri-wing screwdriver.


Offset screwdriver

Offset screwdrivers are the perfect tool for tightening and loosening screws in tight spaces. They feature two offset tips that are at 90 degrees from each other. This tool also features a comfortable black handle for added comfort while driving screws. It also comes with a variety of tips and sizes for various types of screws. Whether you’re a beginner or an experienced mechanic, there’s an offset screwdriver for you.

The offset screwdriver consists of a metal shaft with a flathead or Phillips-type blade that protrudes from the short side. Some models have blades on both ends of the shank, so that they can easily switch from one type to the other. Offset screwdrivers can also have different-sized blades of the same style. The blades on an offset screwdriver can be used for both flathead and Phillips head screws.

Slotted screwdriver

The use of a slotted screwdriver is surprisingly simple, but it can be misused if not used properly. Slotted screwdrivers are typically designed for small, recessed screws, and are not suitable for large screws. For this reason, it’s important to match the screw slot and the size of the slotted screwdriver with the desired fastening torque. However, if you’re unsure about the correct use of this tool, here are a few tips that will help you pick up the right slotted screwdriver.

A slotted screwdriver is distinguishable by its blade-like flat tip, which fits into a slotted screw head. It is the most ancient type of screwdriver and is different from Phillips head screwdrivers, which have ridges on one side and a pointy tip. Other types of slotted screwdrivers include keystone and cabinet variants. The keystone is a more ergonomically-designed design, while the cabinet variant is more rigid and has a wider grip.

Tri-wing screwdriver

There are various types of tri-wing screwdrivers on the market. Rannb, EMiEN, GCA, tatoko, Kannony Wind, and the like are among the top brands. This handy tool is designed for use in tight spaces. Its blade is made of chrome-vandium-molybdenum steel. For best results, you must use a screwdriver that is not too large or too small for the job.

The tri-wing screwdriver is often used in the aerospace industry. It features three slotted wings, each with a small triangular hole in the center. These wings are offset from the screw’s center, which makes them particularly useful for precise work. Some tri-wing screwdrivers even feature flat heads, which allow the user to use them safely for a wider range of applications. You can also find specialized tri-wing screwdrivers for electronics and computers.

The safety profile of a Tri-wing screwdriver is a feature of its double-shielded design. Its double-sided profile, with four edges shifted asymmetrically towards the centre, prevents the screw from slipping. The tool’s double-sided design allows for a wider working area and better force distribution, and can even transfer higher torques. If you aren’t sure which screwdriver to choose, consult a local hardware store.

Pozidriv screwdriver

Pozidriv screws are the most common type of externally threaded fastener. They are distinguished by their cruciform socket and radial indentations set at 45 degrees from the main cross. The word «Pozidriv» is derived from German and refers to the drive design. GKN Screws and Fasteners patented the design in 1962. The screwdriver is an important hand tool for any tradesman.

The conical shape of the Phillips cross-head screw makes it easy to insert a screwdriver tip. When tightened, a strong axial force is generated, pushing the screwdriver out of the screw. This phenomenon was originally used for torque delimitation. The Phillips screwdriver, patented in the 1930s, was designed to solve the issues with slotted screws. The term Pozidriv is derived from the word «positive drive.» The Pozidriv screwdriver is not as powerful as a Phillips screwdriver but is far more efficient for most tasks.

As opposed to the Phillips screwdriver, the Pozidriv screwdriver uses a self-centering drive. This driver features four tick marks on the cross, which provide better engagement with the fastener and increase the torque of the fastener. A Pozidriv screwdriver can also fit into a Phillips screw socket, but its head is likely to come out before the fastener is completely tightened.

Keystone screwdriver

The Phillips head screwdriver is ideal for turning screws with a wrench. The screwdriver’s cushion grip handle and reinforced shank make it comfortable to use. It also features a torque-enhancing cushion grip for maximum comfort. Its screwdriver tip is designed to hold a tightening torque even with long periods of use. Its angled shaft also helps prevent accidental slipping and provides better leverage while working.

The 1/4-Inch Square Shaft Keystone Screwdriver by Klein Tool features a cushion grip handle and a sturdy, square-shank design for wrench-assisted turning. Its blade is precision-machined for an accurate fit in the screw slot. Its blade is hardened and vapor-blasted to prevent plate chipping. Color-coded handles and shaft make it easy to identify the type of screwdriver you’re using.

These screwdrivers are available with a number of different tip sizes. Generally speaking, flat blade tips are designed for screw applications where you don’t want to use a screwdriver with a keystone tip. However, keystone-style screwdrivers have a slightly flared blade profile that tapers off at the tip. This added stiffness makes them suitable for tightening applications. Despite this, it is not recommended for screwing recessed objects or fastening loose fitting hardware.

Cabinet screwdriver

The cabinet screwdriver is made of flat bar stock, and some models feature a short hexagonal section at the top of the blade. For higher torque, a ring spanner or open wrench can be used. This style of screwdriver is also available in a flat version that is set at an angle to the small blade. This helps the user access small, recessed screws, while providing additional torque. Here are some other common cabinet screwdriver types:

A Pozidriv screwdriver is better than a Phillips screwdriver. It is recognized by the same symbol as a Phillips screw, and they are also often confused. A Pozidriv screwdriver is a European attempt to overcome the problem of cam-out with Phillips screws. Developed in 1962, the Pozidriv screwdriver was later improved to become the Supadriv screwdriver.

A Phillips screwdriver is a popular hand tool for many construction tasks, but is not always convenient. Phillips drivers fit perfectly into Pozidriv screw sockets. However, a Pozidriv screwdriver has a cruciform socket and rounded corners. This design allows the driver to turn the screw without marring or breaking the fastener. GKN Fasteners developed the Supadriv as a successor to the Pozidriv. Supadriv screws feature a slight angular offset, making it ideal for a wide range of applications, from home improvement to construction.

A Phillips screwdriver can be used for inserting a Pozidriv screw. The Pozidriv screwdriver is only compatible with small-sized screws. If you try to use one of these screwdrivers in a Phillips screw, you may damage the screw and cause the screwdriver to slip or even tear out. You may want to get a Pozidriv screwdriver if you need a small screwdriver.


A good Phillips head screwdriver is essential for turning screws in tight spaces. Its reinforced shank and cushion-grip handle help improve torque and comfort while turning screws. These tools also make fastening and loosening easier and faster than ever. The following are the most important features of a good screwdriver. Let’s examine each one in detail. To determine whether it is the right one for you, choose the size that fits your hand.
