6 point screw driver

They are of two types according to their application: keystone and cabinet. These were invented in 19th century by Henry Phillips with an aim to introduce the power driven screwdrivers in most of the industries. When you see these screwdrivers from the front, the tip looks like a cross sign.

These types of screwdrivers also shows cam- out effect but it does purposely when the torque exceeds a limit while tightening up of screw which resist the damage of screwdriver profile and screw and clearly extends the life of the tool. The pozidriv screwdriver, unlike Phillips screwdriver, has two cross sign which are offset at 45 degree angles.

These are designed and widely used in Europe. The engagement of quite tapered square shape opening screw with the square protrusion, with no angle involved, neglects the cam-out effect, thus improve centering. Slight Taper shape at the front of the tool provides a good locking with the screw and thus makes it more comfortable for use. These screwdrivers types were first used for industrial purpose by ford motor company, because these drivers speed up the production, reduce damages, and highly reliable.

Torx screwdriver is becoming very common and often used by automotive technicians. Many times they are called as star tips by technician. This driver has a star shape tip with 6 rounded lobes. Because of the circular geometry of the lobes there is low radial force in a torx screwdriver, which increases the life of the screw and the screwdriver bit.

Unlike Phillips or pozidriv screwdrivers, much higher torque can be transferred with the same amount of force with no chance of tool slipping, even at high driving speed power tools, which makes its more reliable to use. Torx types of screwdrivers comes in variety of sizes and uses a number system to determine the size of the tip like T8, T10, T15, T25 etc.

It has six straight lobes, like hexagon. These are used to fasten often bolts rather than screws. You must have seen these bits in your ratchet box for tightening up or loosing hex bolts, nuts and screws.

No slipping or cam- out effect takes place while driving this hence most of the power driver tools can be fitted with hex arrangement bits and thus makes the production fast and with less error. In this article we have learnt about 6 most commonly used types of screwdrivers with their images. If you find anything missing or incorrect than lets us remind through your valuable comments. Thanks in advance. You may be seen these bits in your bitcoin box to tighten or lose hex bolts , nuts , and screws.

There is no sliding or cam-out effect when driving it, so the most powerful driver tools can be fitted with hex arranging bits and thus, it produces faster and with less error. The Offset screwdrivers have also a flat blade. But no handle is used in these screwdrivers. Their shank is turned at 90 angles at both ends and bits are made on both ends.

In cases of narrow or slanting spaces, where ordinary flat screwdriver cannot work, this offset screwdriver is used. It is shown in the figure. Watchmaker screwdrivers are available in sets. In a set there are six screwdrivers, having number markings from 0 to 5.

The smaller the number of the screwdriver, the smaller and thinner is its bit. In place of the handle, a cap is fixed to the shank. The cap is fixed to the shank in such a way that both cap and the shank can be moved independently. For tightening or loosening a screw, the tip is placed at the head of the screw, and the cap is pressed with one finger, while with other fingers shank is rotated. A watchmaker screwdriver can be used in all kinds of instruments and watches. In appearance, it looks as shown in the figure.

These types of screwdrivers are used throughout the automobile industry and are commonly used in older GM vehicles. The clutch head screwdriver is also known as bow-tie drivers, these drivers are used to work screws that have a bow-tie-shaped slot. The clutch screwdriver begins with higher torque and can resist greater turning force. But, this type of screw can also be tight and loose slotted drivers. There is another safe way that it can be screwed by a slotted driver but not loosened.

The tip of these types of screwdrivers is provided with a sharp point, unlike Philip Driver, it has bluntly rounded points. In addition, the angle of the tip is more like 45 degrees than the Phillip drivers. This driver is used on nautical equipment. The Frearson driver , also known as Reed or Prince, is pretty similar to the Philippe screwdriver in design, with some changes. The different shape allows the driver to take out higher torque than the Phillips and to operate on Frearson screws of all sizes as well as a large number of Phillip screws.

These types of screwdrivers are very familiar in the electronic industry and tech giants such as Nintendo and Apple apply them in their phones, gaming systems, and other devices. The tri-point driver makes a tip that has three blades set at an angle of degrees, which is Y-shaped. So, It is also known as 3-prong or Y-tip drivers. Tri-point drivers also have safety issues only that come with tri-angle driver compatibility with hex drivers.

These types of screwdrivers were mostly used in the toy, electronics, and appliance industries and were added to improve safety. It is also known as three-angle screwdrivers. It has a triangle-shaped tip for slotting on the screw head with a triangle shape. The tip of the tri-wing drivers resembles that of some pinwheels and is used to operate on screws that have triangular sockets with three wing sizes.

Because these screws have such a different slot, it is difficult to remove them without a tri-wing driver. Tri-wing screwdrivers are costly and not easily available like other drivers. These drivers were previously manufactured for use in aerospace engineering, but now you can easily found them in home electronics.

The carpenter screwdriver is made of a round rod and flat tip. Its handle is made flat from two sides as shown in the figure. This enables the worker to exert full force or the screwdriver. The bolster screwdriver has a type of nut, which is welded to the top of the shaft under the handle. If a screw is tightened on a surface, you can loosen it by applying additional torque by turning the welded nut with the help of a wrench.

The multipurpose screwdriver has a shank with a hexagonal hole at the end where it can fit a variety of drivers on both sides, with drivers or depending on the use of the set. Because they offer more versatility and economy of space, they are a very common toolset among those who have only basic requirements. Many of screwdrivers also come with changes to their handles and shanks. The optional design helps to eject more torque and offer enough clearance.

These types of screwdrivers are charged by electricity, which means that you do not need to use your muscles to exert torque. It can work a screw easily and quickly, especially for those with a broken head. Therefore, it is also known as power screwdrivers or screw guns. It is generally known for its application on cars, but the thing that pressure requires equipment.

T his type of screwdrivers can offer highly specific uses including everything from military repairs to aircraft. T his type of screwdriver comes with an electric cord. But, they are not very common as they need to be transported to a nearby power source. Still, they provide a constant power supply and are highly efficient. T his type of screwdriver is provided with a rechargeable battery which means that they come with the advantages of both electrical and battery-powered screwdrivers.

Accidentally, this makes them heavier and as the battery charge decreases, they also lose torque. It has a magnetic tip that holds the screw, allowing you to insert the screw in or out with just one hand. More and more manual screwdrivers are now being manufactured with magnetic tips.

They are precision instruments that employ small screws on pocket watches and eyeglasses. It is also known as a watch or eyeglass driver. They are usually Philips and flat head screwdrivers.

T his type of screwdriver is operated with small batteries, which means they come in a compact design. Although it is not as powerful as other screwdrivers, it can easily fit into your toolbox. In these types of screwdrivers , a spring or ratchet is fitted in the handle.

There is a button on its handle. When this button is pressed, the shank of the ratchet screw starts revolving through the spring. When the button is left free, again the shank comes to its original position. With its help screws can be quickly tightening or loosening. As you know, A typical simple screwdriver has a handle and shaft that the user attaches to the screw head before turning the handle used for tightening or loosening of screws.
