History of Screw Drivers
The root of screwdrivers dated dorsum to the century when the tools were made to tighten the newly-invented screws inward engines of nation of war as well as suits of armors. The screws during that fourth dimension consisted of a abrupt threaded needle with a slot cutting inward the caput for tightening. As screws evolved, so did screwdrivers, as, without the right head, it would live on virtually impossible to take away a specific type of screw.
However, non many things receive got changed nearly the screwdriver since the Middle Ages as well as the alone innovations inward the past times several centuries receive got been inward the cloth used as well as the shape of the drives as well as the grip designs. Despite this (or maybe, because of this) the screwdriver remains i of the most of import tools inward the manufacturing as well as abode improvement industry.
Here’s everything yous demand to know nearly screwdrivers:
Common Types of Drives
Most of us receive got heard of a few different types of screwdrivers but inward reality, there is a broad range, containing dozens of different versions of drives, to lead from. Here are some of the most used types:
Slotted Drivers
The slotted drivers, also known equally the apartment head, apartment blade or direct drivers, are the oldest forms of screwdrivers as well as are worked on screws with a elementary slot spanning the width of the screw.
These blades are flat-planed as well as come upward inward different sizes to accommodate inward screws of diverse sizes. Usually, yous volition run into ii sizes, the 5.5 mm as well as the 8 mm screwdriver inward your abode tool kit. The slotted screwdriver also gave nascency to many different versions, which nosotros volition hash out below.
High character slotted screwdrivers receive got almost parallel tapered tips that help to pocket the slot tightly as well as foreclose slippage. Care must live on applied when using this screwdriver equally hard push clit per unit of measurement area tin give the sack drive the screwdriver to sideslip as well as scratch the surface of the cloth or embed itself inward your hand.
Cabinet makers prefer to exercise slotted screws equally they receive got pride inward aligning the slots upward to create their piece of employment expect genuinely neat.
There are ii principal categories of slotted screwdrivers:
- Flared Slotted Screwdrivers: A flared screwdriver has a tip that is slightly flattened so that its width is wider than the shaft.
- Parallel Screwdrivers: A screwdrivers with the border the same width equally the driver shaft. This characteristic is really useful when loosening or tightening screws within pre-drilled holes.
Phillips Screwdriver
The Phillips screwdriver is also known equally a crosshead, because of its cruciform head; however, superior character drivers, the tip is somewhat rounded. These screwdrivers are made to fit into screw heads which are made inward the West as well as do non receive got abrupt tips similar slotted screws.
The Phillips screwdriver has an angled tip with thinner blades which agency yous tin give the sack slot the driver deeper into the screw caput without risking the driver slipping out from the sides, equally tin give the sack hit off with slotted drivers. This also agency yous tin give the sack exert a greater torque on the screwdrivers. Because of this, Phillips screwdrivers are used inward almost every champaign as well as are the most preferred sort of drivers.
Pozidriv
The Pozidriv is considered to live on an upgraded version of the Phillips screwdriver as well as was made to cut down the jeopardy of the drives camming out when high push clit per unit of measurement area is applied.
The Pozidriv is characterized past times 4 shallow lines radiating from the center. The tip is smaller as well as blunter than that of Phillips screwdriver as well as contains ribs alongside the blades. The increased contact with the screw caput agency yous tin give the sack apply to a greater extent than turning forcefulness without the danger of the driver slipping out.
The Pozidriv arrangement is really efficient as well as is less likely to intermission the screw caput or the tip when the correct push clit per unit of measurement area is applied. These screwdrivers ordinarily come upward inward sizes from 1 to 3.
Torx Drivers
These trademarked screwdrivers were i time pop inward the safety as well as manufacturing champaign but receive got similar a shot acquire really mutual inward commercial fields equally well.
The screwdriver features a blade shaped inward the shape of a recessed six-pointed star but with the abrupt angles rounded off. This improves the contact expanse betwixt the screwdriver tip as well as the screw caput as well as provides improved torque. Because of this, the screwdriver tin give the sack withstand maximum torque as well as does non easily sideslip out or break.
Torque screwdrivers come upward inward size ranging from 0.03’’ to 0.81’’ as well as are designated shape T1 to T100 numbers. The most mutual sizes used inward the edifice are from T15 as well as T25.
Hex Drivers
Hex drivers receive got a hexagonal let out rather than a blade as well as a tip, thence the cite hex drive. They are also known equally a hex key, hex socket or Allen wrench. It is an odd hybrid shape of screwdrivers which is used to fasten bolts rather than screws. The direct grip of the hex socket agency yous tin give the sack plough the bolt with really piffling infinite required.
The most mutual exercise of hex drivers is bike maintenance equally good equally assembling furniture. However, using a T0-handle Allen wrench is a meliorate selection when doing these tasks since it offers higher torque application than what comes with a narrow screwdriver handle.
Robertson Drivers
Robertson screwdrivers, also known equally foursquare caput drivers, are the to the lowest degree commonly used screwdrivers. However, it is quite pop inward its dry soil of origin, Canada, as well as has a really high torque tolerance, which is fifty-fifty sometimes considered to live on the highest of all drivers.
Robertson drivers receive got a recessed foursquare socket. Since at that spot is no tip, it is highly unlikely that the Robertson screwdriver falls out of the recess, which agency really high turning forcefulness tin give the sack live on applied. In fact, it is to a greater extent than likely that the bolt volition snap off earlier the driver slips.
The screwdriver is most commonly used inward the slice of furniture as well as automotive manufacture because it is really durable. Although non constitute inward basic abode tool kits, they are included inward comprehensive screwdriver sets.
Tri-wing Drivers
The tip of the Tri-wing drivers somewhat resemble a pinwheel as well as is used to piece of employment screws that receive got triangular sockets with 3 fly extensions. Since these screws receive got such a unique slot, they are impossible to take away without tri-wing drivers.
These drivers were commencement manufactured to live on used inward aerospace technology scientific discipline but tin give the sack similar a shot live on easily constitute inward abode electronics. Tri-wing drivers are expensive as well as non equally easily available equally other drivers. However, their biggest do goodness is that they tin give the sack live on tightened to extremely high torque values.
Tri-wing drivers come upward inward sizes ranging from 1 to 3.
Tri-angle Drivers
Also known equally TAs, these tri-angle screwdrivers receive got a triangle shaped tip for slotting into identify on screw heads with triangular depressions. These drivers were used inward the toys, electronics as well as appliances manufacture as well as were added for increased security. However, a hex screwdriver tin give the sack also pocket TA screws, so non many DIY kits comprise tri-angle drivers.
Tri-Point Drivers
Also known equally 3-prong or Y-tip drivers, the Tri-point driver features a tip with 3 blades laid at 120-degree angles, making a Y shape. The screws made to piece of employment with these drivers are really pop inward the electronic manufacture as well as tech giants similar Nintendo as well as Apple exercise them inward their phones, gaming systems, as well as other devices.
The tri-point drivers also address the safety issues that come upward with tri-angle drivers compatibility with the hex drivers. Tri-point screws tin give the sack alone live on worked with tri-point drivers.
Spanner
Not to live on confused with the British term for a wrench, the spanner is also known equally Snake-Eyes, pig-nose as well as drilled caput driver. These foreign screwdrivers are equipped with a two-prong tip — much similar a barbecue fork — which is used to piece of employment flat-head screws with ii tiny rounded depressions on either side of the head, making it virtually impossible to take away without a spanner.
Since they are really secure, these screwdrivers are ordinarily used past times maintenance workers on omnibus terminals, elevators, restrooms, as well as subways. Spanners are available inward a size hit of 4 to 12.
Clutch Head
Also known equally a bow necktie driver, these tools are used to piece of employment screws which receive got a bow-tie-shaped slot. These screwdrivers are used throughout the automobile manufacture as well as were popularly used inward former GM vehicles.
A clutch screwdriver comes with improved torque as well as tin give the sack withstand the to a greater extent than turning force; however, these types of screws tin give the sack also live on loosened as well as tightened with slotted drivers. There is some other safety version which tin give the sack live on screwed past times a slotted driver but cannot live on loosened.
These types of screwdrivers are constitute inward infrequently maintained places similar prisons.
Bolster Screwdriver
A bolster screwdriver consists of a type of nut welded to the overstep of the shaft beneath the handle. If a screw is stuck tight to a surface, yous tin give the sack loosen it past times putting extra torque past times turning the welded nut with the aid of a wrench. This agency this tool is able to withstand maximum pressure.
Frearson Driver
The Frearson driver, also known equally the Reed as well as Prince, is quite similar inward pattern to the Phillip screwdriver with some subtle changes. The tip of this screwdriver is equipped with a abrupt point, dissimilar the Phillip driver that has bluntly rounded points. Moreover, the angle of the tip is closer to 45 degrees than Phillip drivers.
The unique shape allows the driver to exert to a greater extent than torque than a Phillips as well as to piece of employment on Frearson screws of all sizes equally good equally a large number of Phillip screws. Because of this, the screwdriver is used on nautical equipment.
Japanese Industrial Standard Screwdriver
These screwdrivers receive got a cruciform shape similar Phillips but are singed to live on resistant to camming out. The JIS screws tin give the sack live on constitute on many character products imported from Japan. Even though the JIS screws tin give the sack live on opened past times Phillips as well as Frearson drivers, the procedure is non slow as well as tin give the sack harm or divide the head.
JIS-compatible screws receive got a pocket-sized dot close the slot which distinguished them from other screws.
Styles of Screwdrivers
The inward a higher identify screwdrivers were classified based on the screws they worked with; however, many of these also come upward with variations inward their handles and shank. The option pattern helps to exert to a greater extent than torque as well as offering meliorate clearance.
Here are some of the most pop styles:
Electric
These screwdrivers are powered past times electricity, which agency yous don’t demand to exercise your muscles to apply torque. They are also known equally ability screwdrivers as well as screw guns as well as tin give the sack easily as well as rapidly piece of employment a screw, particularly those with broken heads.
Battery-powered
These screwdrivers are run with pocket-sized batteries, which agency they come upward inward compact designs. Although non equally powerful equally other screwdrivers, they tin give the sack easily fit inward your tool belt.
Corded
Corded screwdrivers come upward with an electrical cord; however, they are non really pop equally they demand to live on tethered to a nearby ability source. However, they give out a constant ability render as well as are extremely efficient.
Cordless
These screwdrivers are equipped with a rechargeable battery which agency they come upward with the benefits of both electrical as well as battery-powered screwdrivers. Unfortunately, that also makes them bulkier as well as heavier as well as equally the battery accuse wears down, they lose torque equally well.
Magnetic
Magnetic screwdrivers receive got a magnetic tip which holds the screw, allowing yous to position inward or line out the screw with simply i hand. More as well as to a greater extent than manual screwdrivers are similar a shot existence built with magnetic tips.
Jeweler’s
Also known equally sentry or eyeglass driver, they are precision devices that piece of employment tiny screws on pocket watches as well as eyeglasses. Jeweler’s screwdrivers are generally Phillips or slotted drivers.
Ratcheting
A ratchet screwdriver allows yous to apply torque alone inward i direction. Turning it inward the contrary management volition allow the ratchet to disengage, allowing gratis rotation.
This allows yous to driblet dead along concur of your screwdriver piece yous are turning it until your wrist reaches its maximum twist. You tin give the sack as well as so simply move out the driver caput inward the screw as well as and so i time your wrist is ready, twist it dorsum again.
This is really useful for projects where removing the screwdriver as well as and so finding the screw caput i time again is challenging.
