Read Also: Different Types of Springs and Their Applications [Full Guide] The Function of Various Types of Screwdrivers The majority of screwdriver sets have plastic or acrylic handles, sometimes with a rubbery coating for extra grip, but you’ll also find wooden-handled screwdrivers, as well. Whichever type of handle you choose, it should fit in your hand comfortably, even when applying pressure to turn a tight screw, without slipping or causing pain. Look for handles that are marked ergonomic or “comfort grip” if you prefer tools that are easy on your hands. The Wera Kraftform Comfort Insulated Screwdriver Set has especially comfortable handles and is insulated for use around live wiring, as well. If you’ve ever been to a hardware store, you’ve probably seen hundreds of screwdrivers in a variety of designs, sizes, and other characteristics. Actually, the type of screwdriver you use depends entirely on the type of recess or screw drive you use.
Is it possible to build a toolkit without screwdrivers? We don’t think so. In the average home, you’ll find a vast array of different screws, all of which will – as sod’s law dictates – require the screwdriver which isn’t the one you’re holding in your hand. This is why it pays to invest in the best screwdriver set you can afford, so you’ll always have the right tool for any screw – be it Posidrive or Phillips, Torx or truss head. At the end of testing, each screwdriver or screwdriver bit was dropped to the ground from the tester’s eye level, and the tool was then examined for any signs of damage. Slot-head screws have a single straight notch for the corresponding flat-head or slotted screwdriver. These screws are commonly used in cabinetry and furniture, as well as outlet covers and other basic household items that are screwed in place. Slat-head screws withstand much more torque than Phillips-head screws before the screwdriver slips, meaning they can tighten more than a Phillips-head screw. From smallest to largest, the most common sizes of slotted screwdrivers are 1/8-inch, 5/32-inch, 3/16-inch, 1/4-inch, 5/16-inch, and 3/8 inch. Handle, generally wooden or plastic handles, are fixed to the screwdrivers. To save the wooden handle from being broken, an iron is fixed to the handle.#2. Shank It’s worth noting that metric bits have almost completely replaced Imperial-sized ones, but screws put in 50 years ago haven’t heard about this. Still, it’s possible to use a driver that’s slightly too small to loosen a screw, so it’s not worth worrying about having every possible size in your collection. A choice of the most common sizes, in both flathead and Phillips (cross-shaped) will do for most day-to-day jobs.The grip is usually made of metal, plastic, rubber, or wood. The handle is usually designed to exert maximum torque without your hand slipping. Plastic handles are commonly used because of their durability, but rubber grips are also added to provide comfort while using it.
The handle has a magnetic holder that helps keep the bit in place. We found this screwdriver set to be easy to use, and the ergonomic handle comfortable to grip. It easily handled all of our tests, but our product tester did comment that it was a bit difficult to get some of the bits out of the storage case. Still, if you handle a lot of projects that require hex keys, this is a great set. On the upper part, either there is a hole through which a wire is passed, or this end is made flat so that when this part is fixed to handle, it does not allow the shank to move separately. These are generally made of carbon steel. #3 Blade The purpose of a screwdriver is to both insert and remove screws and nuts. If you want to replace a watch’s battery, you won’t use the same screwdriver you use to hang a shelf on a wall. The different functional screwdriver design types are described below. 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 find them in home electronics. #14 Carpenter Screwdriver A screwdriver is used for tightening or loosening the screw. A round rod with a flat end, having a handle at the other end, is called a screwdriver. The length of a screwdriver is measured, excluding the handle. The length of a screwdriver varies from 50 millimeters i.e., 2” to 18”.Your home and car emergency kits should include basic screwdrivers, and with this reasonably priced tool from LENOX, you hardly need any space to stash this 9-in-1 screwdriver. The comfortably padded handle serves as storage for the included bits, which include Phillips head, flat head, square head, and nut drivers. This is a no-frills tool, but it performed very well in our tests, turning screws without slipping or bending, prying open the lid of a paint can without much effort, and surviving the drop test without damage. Everything about this set is sensibly designed, from the shot-blasted tips that reduce breakage, to the ergonomic shapes and smooth domed ends to the handles that allow them to spin easily. Colour-coded ends mean you’ll soon be able to identify the tool you want without having to peer at the tip. Yankee Screwdriver: Instead of using ball bearings, this screwdriver uses a spring-loaded mechanism. Instead of twisting the screw with your wrist, you place the screw head against the screw and push it to tighten.
I assume you were confused between a screwdriver and a screw drive, though? Just keep reading, and all of your confusion will be resolved. Now the real testing began. All screwdrivers were used to carry out functions appropriate to that type of tool. Regular screwdrivers were used to drive screws into wood, pry open the lid of a paint can, and assemble furniture. Precision screwdrivers were used to open and close video game controllers and tighten screws on eyeglasses. Screwdriver bits designed for use in power drills were inserted into the correct type of drill, such as electric screwdriver, drill/driver, or impact driver, and then evaluated for performance. Phillips-head screws have a "+"-shaped notch that requires a corresponding Phillips-head screwdriver to tighten or loosen. These screws are commonly used for all manners of fastening. As a general rule, screws with a Phillips head only tighten to a certain point before the screwdriver “slips,” which prevents over-tightening and stripping of the screw. From smallest to largest, the most common sizes of Phillips screwdrivers are #000, #00, #0, #1, #2, and #3. Something a little bit different. Wera launched its handle shape in the 1960s, basing it on the contours of the human hand. And despite a few tweaks, it’s stayed basically the same ever since. Human hands, Wera says, haven’t changed in that time either. One of the greatest tool inventions ever made is the screwdriver. Screwdrivers were reportedly created in the 15th century, and as we moved into the 21st century, you could find them in almost every toolbox.Sets that comprise a universal handle with many interchangeable tips are popular because they’re light and easy to carry, but once you lose one of the tips it tends to stay lost – they’re not very big and are often dull in colour. Lose too many and you’ll have to buy a new set of tips, or potentially replace the whole set. Can’t I just buy any old cheap screwdrivers? Insulated screwdrivers provide safety when working around live wiring. While not a requirement for most common tasks around the home, these are a must if you take on projects that might involve any type of wiring or electrical work. The Wera Kraftform Comfort Insulated Screwdriver Set includes six screwdrivers: two Phillips head and four slot-head in the most common sizes. Each screwdriver is guaranteed for safe working standards up to 1,000 volts. The set also includes a voltage detector. However, there is no carrying case. We loved the completeness of this set, as well as the strong performance and sturdiness of all the included pieces. Our product tester appreciated the well-organized carrying case, which is labeled for size and type on all of the components, and which holds the bits in place securely but isn't too tight to remove them easily for use. While not powerful enough for professional use, this cordless screwdriver is more than sufficient for typical tasks around the house, such as tightening up loose screws on furniture, hanging drapes, installing shelves, or assembling furniture. The lithium-ion battery can hold a charge up to 18 months, depending on how often and how long you use the tool, and comes with a charger. The set includes a plastic organizer for the bits but no case for the screwdriver itself.
