It would be very difficult to find an American household that did not have at least one screwdriver. Perhaps the most ubiquitous of hand tools, the screwdriver has a long genealogy, the result of a complicated manufacturing process. Archimedes is considered to have invented the screw in the third century B.

The screwdriver is a tooling agent that can be manual or power and it is used for screwing and unscrewing screws. Its shaft is made up of tough steel to resist twisting and bending.

List of screw drives

The screwdriver has been considered one of the greatest inventions among tools. According to many Historians, screwdrivers were invented in the 15th century and as we a made transition to 21st century you find them in every toolbox commonly.

If you ever visited a tool shop, you must have seen hundreds of screwdrivers of different styles, shapes, size or anything else. Well, screwdriver is entirely depending on the screw drive type or recess type. Well I know you must have got confused between a screwdriver and a screw drive? Your confusion will sort out just keep on reading. Here you will learn 6 different types of screwdrivers that are most commonly used. Image source. Screw drive also known as the recess which is a shape or groove made on the head of the screws which allows screwdriver to apply torque on it, while the screwdriver is mainly a tool to drive the screw in clockwise or anticlockwise direction.

A basic screwdriver has a handle at its one hand and a shaft, groove at the tip of shaft, on the other. The grooved part rests on the screw drive to drive the screw into the material. There are many types of screwdrivers according to the design of the screw head drive or recess type, but in this article we are going to discuss some common types of screwdriver which are mostly used in every project. It is one of the oldest types of screwdriver.

It was invented in the 15th century in Europe and one of the most common types of screwdrivers. As the name suggest it has a flat shape shaft tip with a single slot which engages with the slotted screw head only. Now what does it mean? 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. Image Source. 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.

The following heads are categorized based on frequency, with some of the less-common drives being classified as "tamper-resistant". Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips 00". These sizes do not necessarily describe a particular dimension of the drive shape, but rather are arbitrary designations. Slot screw drives have a single horizontal indentation the slot in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. This form was the first type of screw drive to be developed, and for centuries, it was the simplest and cheapest to make.

Screwdrivers are one of the first tools a child is introduced to. They perform a simple function and have a very simple design. Or do they? Most people have heard of at least two types of screwdriver, but there is actually a wide range to choose from. From the common Torx to the not-so-common tri-point, every shape has its own purpose. There are several types of screwdriver heads that are commonly needed for items around the house.

Let's take a moment and explore 14 different screwdriver types and what they're used for. Common Screwdrivers. Slotted. Phillips. Torx. Hex. Robertson. Other Types of Screwdriver. Clutch Head. Frearson. JIS (Japanese Industrial Standard) Nut Driver. Pozidriv. Spanner. Styles. Electric. Battery-Operated. Corded.

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. 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. 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.

Особенно таких, как Хейл, - зеленых и наивных. Сьюзан посмотрела на него и подумала о том, как жаль, что этот человек, талантливый и очень ценный для АНБ, не понимает важности дела, которым занимается агентство.

Стратмор подался вперед и повернул к Сьюзан монитор компьютера. На черном поле светилось небольшое желтое окно, на котором виднелись две строчки: ВРЕМЯ ПОИСКА: 15:09:33 ИСКОМЫЙ ШИФР: Сьюзан недоуменно смотрела на экран. Получалось, что ТРАНСТЕКСТ трудится над шифром больше пятнадцати часов.

Он слышал приятный голос сеньора Ролдана из агентства сопровождения Белена. У нас только две рыжеволосые… Две рыжеволосые, Иммакулада и Росио… Росио… Росио… Беккер остановился как вкопанный. А еще считаюсь лингвистом. Он не мог понять, как до него не дошло. Росио - одно из самых популярных женских имен в Испании.


Похоже, она от меня не отвяжется. И он решил не реагировать на сообщение. ГЛАВА 79 Стратмор спрятал пейджер в карман и, посмотрев в сторону Третьего узла, протянул руку, чтобы вести Сьюзан за. - Пошли. Но их пальцы не встретились.

И все переформатирую. - Нет! - жестко парировал Стратмор.  - Не делай .

На лице лейтенанта появилось оскорбленное выражение, какое бывает только у испанцев. - Вы хотите сказать, что даже не познакомитесь с Севильей. - Я был здесь несколько лет .
