These are widely used in European countries. This shape does not completely overcome the cam-out effect but gives better resistance to slipping and provides more stability than the Phillip screwdriver. So, it is used for use that requires huge torque for tightening of the screw. It has six straight portions like a hexagon.
These are often used to fasten bolts instead of screws. 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 types of screwdrivers have a pointed cross-head tip that matches a self-centering, cross-head screw. Believe it or not, Phillips heads were originally designed to cause the driver to cam out, to prevent over-tightening! Check out our article What is Cam Out to learn more. Similar to Phillips bits, Pozidriv offers another four points of contact that grasps screws even more securely to protect against camout.
Pozidriv screws and bits seem popular overseas, but we now see them appearing all over in the US market…and we love it! Slotted or flat heat screwdrivers, one of the oldest types of screwdriver, started in the early s. This type of screwdriver bit works with slotted screws that have a cut through the top of the head. When choosing what size flat blade screwdriver to use, always make sure the tip is the width of the fastener and the bit fits snugly.
If the flat head driver or bit wobbles in the screw—you can slide right off the head. The advantage of this screw lies in its simplicity. Everything else presents a stark disadvantage. In general, most Pros try not to use these unless absolutely necessary. Can you guess where you find these most often? We refer to hex head screws as Allen screws. These are a useful type of fastener because of how effectively they limiting the amount of slip.
An Allen or hex screw bit often makes its way into furniture but even automotive applications use them. We also find these types of screwdriver bits on bicycles.
TORX head screws and bits also commonly get referred to as Star bits. These-six-pointed bits resist slippage or cam-out better than slot head or Phillips head designs. In fact, TORX head bits and screwdrivers were specifically designed to prevent it. An adjustment to Torx, Torx plus took that star design and squared off the edges.
That resulted in more surface-contact area. Of the many types of screwdriver bits on the market, Torq Plus might just be the most grippy and stable. To make things even more complicated, Torx Plus security bits have just 5 lobes instead of 4.
Square drive bits, sometimes referred to as Robertson bits, find their home in a variety of places. The manufacturers have included two battery packs, ensuring that the user could keep on doing his job with one battery while charging the other. The dual position handle was one of the primary factors that led me to purchase this device.
Let us dive in and see how this beauty performs. This tool is ideal for hobbyists, DIY enthusiasts, computer repair specialists, electricians, appliance repair personnel, as well as professionals. Its lightweight along with its powerful LED light ensures that one can use it for tasks that are beyond the reach of other similar devices. For example, you can use it to remove and fix screws in computers without disassembling it.
It is the perfect tool when you need to lie beneath an object and there is hardly enough space between the floor and the working area. While this tool is not ideal for major driving or drilling, it is perfect for general light screw driving tasks. The torque is great even at the lowest setting and works fine up to the last few seconds of battery life, a feature that other similar devices cannot boast of.
It is applicable in small electronics industries when trying to place screws in hard-to-reach locations. Its use is easy because they stick to your screwdriver. You can magnetize your existing screwdriver using a rare earth magnet instead of buying new sets of magnetic tipped screwdrivers.
Ratcheting screwdrivers reduce the lift as well as save time. It repositions the screwdriver tip after every turn. Ratcheting screwdrivers have an internal ball-bearing mechanism that allows the user to make multiple turns of the screw with an easy back-and-forth wrist action. By switching a button on the screwdriver the ratcheting action can be changed from one direction to the others so that it is applicable to insert screws like clockwise directional motion and remove screws by the counter-clockwise direction of motion.
Yankee screwdriver operates on a spring-loaded ratcheting principle that has a specific ratcheting screwdriver mechanism. The tip of a Yankee screwdriver in the screw head and pushes firmly toward the screw Instead of using wrist action to turn the screwdriver. The pressure causes the screwdriver shank to turn and the tension spring inside pushes the handle back to make it to the starting position. The 8 pieces right-angle screwdriver is designed to get into areas with only 1 in. The convenient ratcheting mechanism provides ample torque for tightening and loosening hardware.
The screwdrivers come with 7 hex bits. Designed to get into hard-to-reach areas — requires only 1 in. It has forged steel handle and precision tips that can be inserted anywhere even in the narrow locations.
Tips are precision formed to fit the fastener and Shaft is forged from high strength alloy steel. It meets ANSI specifications and has degree offset bits that enable the user to get around obstructions Includes 4 different bit sizes.
So here we have studied all the different types of screwdriver in detail. Do share this article with your friends and family.
