types of screwdriver heads

The Torx, because of its many splines, has a lot of surface area in touch with the screw or Torx bolt and as such is much less likely to slip off or break. The gauge can be preset as in the case of a battery drill driver or a wheel nut air spanner. Ratchet screwdrivers come in the slot or flat headed variety, Phillips and Pozidriv. Of course the type of screwdriver you use will depend on the type of screw you are working with so do please go along to our project page on the different types of screw. A nut spinner is essentially a screwdriver for nuts and bolts. It is more common however, as with screwdrivers and bit holders, to buy Nut Spinners in a set with a socket holder on the end of the shaft so many sockets can be attached as required. Not the most popular tool amongst electricians, mains power tester drivers work by allowing current to flow up to a resister which reduces the level to a safe one. They allow for massive manoeuvrability in the most confined spaces. Much the same as Hex keys, Torx Keys offer more leverage than a Torx screwdriver and the kit form of a Torx set is such that in most of its formats it is difficult to lose an individual Torx key. When working in kitchen cupboards and awkward places an angled screwdriver bit holder is essential. The screwdriver bits themselves are the usual ones but when placed in an electric screwdriver or even a hand held quick change screwdriver, the angles bit holder makes it possible to put screws into the most inaccessible place. This is called the yield point. A ratchet is a piece of engineering which, via cogs and other bits, allow the moving part of a tool to only move one way with any torque. The instrument driver in the image below shows, as many of them do, a pen clip on the body of the driver to keep it safe in your pocket, especially the top pocket of overalls when bending over in the workshop. It really is a nuisance using a bit holder which allows the bit to fall out every time the holder is held vertically downwards, Similarly, sometimes the fit of Posidrive or Phillips is a little tight and, if the bit holder is not magnetic, the bit can stay in the screw when you withdraw the driver. The list that follows is as complete as we can make it today. With a much stronger tip that those generally on normal screwdrivers and a shaft set much more securely into a handle that will not split when hammered, Chisel Drivers really do provide the missing link when something a bit more robust is required.{/INSERTKEYS}{/PARAGRAPH} The folding sets, like the Stanley Fatmax Torx Set shown here allows the whole bunch of keys to fold away neatly in the handle. There are plusses and minuses to this. Cabinet makers and the old breed of joiners prefer to use slotted screws as, when fixing many times, they can line all the slots up to make the job look really neat. Precision screwdrivers, because the body is so thin, almost always have a rotating cap at the end. Obviously much smaller, the bits are often kept inside the driver for safe keeping. Suitable for most little grub screws and tiny hinge screws when it comes to removing batteries from torches or other electrical items, its always a good idea to have a precision screwdriver set in the toolbag. This is shown by a neon light. Ratchet stubbies are one of the most useful tools in the box for kitchen fitters. They are also very good, if you have strong hands, for undoing very tight screws because your hand action is close to the screw head with a stubby and because there is no flex in the shaft you are exerting more torque directly on the end of the screwdriver. With screwdriver kits of all kinds where a bit holder is required, the case is as important as the driver itself as lost screwdriver bits, especially the popular sizes, pretty much render the kit useless. Turning it the other way will be very easy as the ratchet disengages from the screwdriver and allows free rotation. The "Daddy" of all screwdrivers. Really it is a mix of a Phillips, Pozidriv and a Hex bolt all in one. An offset ratchet screwdriver is a ratchet spanner into which special screwdriver bits are inserted at a right angle to the spanner arm. They also come in the form of a kit with a ratchet bit holder and several different types of head. A cylindrical shaft is attached to a socket which slides over the nut or bolt to undo it in the conventional screwdriver or spanner technique. {PARAGRAPH}{INSERTKEYS}In this project we take a look at the different types of screwdriver and the huge variety of heads and blades including the Phillips, Pozidriv and Slotted heads and what different screws and fixings they should be used with. A ratchet screwdriver therefore, can only apply torque To understand torque, see the section on a torque screwdrivers below when turned in one direction. The Chisel Driver is a great tool to have. The slotted, flared or flat screwdriver precedes all other types of screwdriver and fits neatly into a slot on the top of the screw. Nut Spinners can be bought in fixed sizes and these usually have hollow shafts which allow a long thread to be swallowed up by the shaft while the socket at the end sits over the nut. Usually in a DIYers toolbox you would expect to see two sizes which are the most common — 5. The image is there to show you what the head of a Torx screw looks like and you can see at a glance that providing the correct size Torx bit or key is used, there is little chance that it will slip or break and that a lot of pressure can be applied. Operating in exactly the same way as a conventional ratchet screwdriver, they often contain screwdriver bits in the handle making this a very versatile tool indeed. This keeps the screwdriver bit in place when the bit is facing downwards. Quite often used for opening tins of paint, the slotted screwdriver comes in many sizes from tiny precision or watchmakers screwdrivers to huge industrial sizes. If used properly and safely however, they are a very useful tool for checking if something is live quickly. Your local garage for example, has a table of torque values for the wheel nuts on your car. Torque can be measured by having a gauge connected to the arm that is applying the force. Very clever people have lists of materials and objects and have formulated the yield point of all of them in some very clever tables. Objects of all kinds have a breaking point and when too much torque is applied to say a screw, the screw breaks or at the very least, twists in distortion. Screws have evolved from the original idea of a pointed threaded nail with a slot cut in the head, to security screws that are almost impossible to remove, without the right type of screwdriver that is. The Ryobi kit shown in the image comes also with a bit holder. This system of fixing or undoing screws this way is absolutely great as it means that the action of your hand on the screw can happen in a much more confined space than with a conventional screwdriver. By turning a screwdriver, spanner, steering wheel etc…. Screwdriver bits can be used in hand-held bit holders or electric screwdrivers, drill-drivers or combination drills. When buying a screwdriver which is a holder for screwdriver bits, whether it is hand held or electric, but especially when it is hand held like the one shown in the image below , make sure the bit holder is magnetic. These screwdrivers can also be bought with different bits just as the screwdriver bit sets above. On the downside however, because of the greater depth of the drivers blades, they have to be a little thinner and are more prone to shearing off when the greater torque is used. Torque is a force which tends to cause rotation. The word Torx as a brand-name is a play on the word torque as these bits, and associated drivers are considered to be the way of applying maximum torque to any fixing. We also take a look at the various types of screwdriver design and operation that includes the ratchet, impact driver, nut driver and the insulated VDE screwdrivers for electrical work. Again, Torx screwdrivers can be bought as individually sized drivers but most often come in kits as shown below. The bit is placed into the bit holder in the driver arm and placed into the screw. Bit holder handles with different bits are a brilliant idea but it pays to spend a little bit more for a kit which is contained in a strong case. Once again, when buying a kit, pay special attention to the case it comes in. This allows the driver to nestle in your palm while you twist the shaft with your fingers. Don't want to do this job yourself? This system then allows you to keep hold of the screwdriver while turning it right, to tighten it, then when you have reached the maximum your wrist will turn, you simply leave the driver head in the screw and twist it back so your wrist is ready to tighten again. It is quite common for home improvers, and indeed tradesmen to be caught opening cans of paint with both chisels and screwdrivers. Care must be taken when using a slotted driver as, unless the pressure is applied directly down the length of the screw, the driver can slip out of the slot and scratch the surface of your work or in some cases, embed itself in your hand or finger. They can develop faults, they can be easily dropped into puddles or any other water, they can be dangerous if not used properly. That is how a torque screwdriver works. Take a look at this set of screwdrivers here that are a great example of a set of precision screwdrivers and you will see that, for the price, it is everything you need it to be. It really is fantastic value for money. Insulated screwdrivers are used when working on, or anywhere near electricity. It is always better to use a high impact screwdriver bit in an impact driver as the torque can soon sheer off the fins on a Phillips or Posidrive screwdriver bit if the metal is not strong enough. A great example of one of these versatile tools is the Einhell 18V combination drill and Impact Driver set. Stubbies, or stubby screwdrivers are simply shortened versions of ordinary screwdrivers. Click on any images throughout this section to find out more about the tools shown and buy them if the mood takes you. You are looking for very strong splines that fit snugly into Torx sockets with no slip and maximum pressure. Some joiners even insist that their apprentices make sure that each slot is in the same direction in hinges. Losing sockets of any size can render the kit pretty useless on occasions. It is also very common to see anyone chipping bits of paint from the head of screws with the screwdriver. By putting your finger, or other body part, on the brass cap you are completing a circuit. Because of a system which rotates the screwdriver bit as well as bashing down on it with a hammer action at regular intervals a lot of torque is created which drives the screw into the timber very quickly with the minimum drain on the battery. Ryobi offer one of the least inexpensive Torx kits on the market today that would be acceptable as tradesman standard. This means the end of the driver does not go so far into the screw. Very useful for tight spaces such as between the kitchen units and the wall. Let us help you find a tradesman local to you. While you can do exactly what you like with your tools, they tend not to last as long as you would like if they are used for purposes other than the intended one. The image below shows that the Pozidriv screwdriver has a slightly blunter point than the Phillips. Modern technology soon realised that carrying 15 different types of screwdriver around was a little cumbersome and the screwdriver bit was invented. On one hand more of the screwdriver blades are in touch with the sides of the screw aperture giving, theoretically, more control and the potential for greater torque. If you are considering using a slotted screw please be very careful if using it with a power driver or any kind of electric screwdriver. There is no doubt about it that this really shows pride in ones work. Slotted screws are not designed for power driving and the head can easily be spoiled by a powerful drill-driver simply tearing one side of the slot away. Once more, the case is very important. We also take a look at the huge range of screwdriver bits and kits that are available today and how these can save time on many DIY jobs and space in the toolbox. For more about combination drills, which allow you to drill holes in masonry, steel, plastic and timber as well as being able to use them as a screwdriver. This is especially useful in tight spaces where removing the driver and finding the screw head again could be difficult.
