A screwdriver is a common tool, used to install and remove screws. It is available with manual screwdrivers or electric screwdrivers according the operation mode. A typical manual screwdriver is constructed with a handle and a shaft as well as an end called a tip which is used to insert the screw head before turning the handle.

Basic Screwdriver Structure

The screwdriver basically has three parts: handle, shaft and tip.

• Handle

The screwdriver handle is the part that is held and rotated by human hands. From the perspective of user experience, there are two most important points.

• Ergonomic
  It fits the shape of a human hand. In other words, the screwdriver tool is very handy and very comfortable to hold. Therefore, most of screwdrivers are designed with ergonomic handle.
• Anti-slip
  In an industrial environment, the screwdriver is easily polluted by oil, so the anti-slip design is very necessary to ensure the work efficiency.

Today, many screwdrivers on the market will change the shape of the handle, such as adding particles and grooves to the handle, so as to increase the friction coefficient to enhance the anti-slip function. In addition, adopting rubber material or other methods makes sure the screwdriver handle is anti-slip.

• Shaft (Shank)

The screwdriver shaft is the part of force transmission during use. There are three criteria for a good screwdriver shaft.

• Have enough hardness without losing toughness.
• Good impact resistance.
• Good corrosion resistance.

The common screwdriver shaft uses the same chromium vanadium steel (CR-V) material as wrenches and other tools. After heat treatment, the hardness can reach HRC55-60 or more, and it has good wear resistance. Besides, some top screwdrivers will choose chromium molybdenum steel: Cr-m or S2 alloy steel as a material, all properties of which are better than chromium vanadium steel: Cr-V.

• Drive tip

The tip is the soul of a screwdriver. There are two criteria for judging the quality of the screwdriver tip.

• Hardness
  Like the shaft, it is best to choose the material with high hardness, good toughness and wear resistance as the tip material for the longer service life.
  The coating on the tip helps extend the service life.
• Precision
  The precision of the screwdriver tip refers to the degree of matching with the size and width of the screw head groove.
  In order to increase accuracy, it is necessary to increase the degree of matching between the bit and the screw. The common practice is that the screwdriver head is provided with plated to add friction and the degree of matching. This kind of processing method is very common. It is generally seen that the color of the screwdriver is different because of the plated treatment.

Common Screwdriver Type

With different types and sizes of tips, the screwdrivers come with a variety of shapes to fit all kinds of screw heads. There are Slotted, Phillips, Robertson, Pozidriv, Torx, Hex, Pentalobe, Tri-angle, etc. The Slotted and Phillips screwdrivers are the most commonly used in our lives, as it is must-have for installation and maintenance. It can be said that a screwdriver is used wherever there are screws. The figure as shown below are some common types of screwdrivers.

There are many kinds of screwdrivers for different functions, including the ordinary individual screwdriver with fixed tip type, the screwdriver set with replaceable bits, the ratchet screwdriver and the electric screwdriver. So you can select a suitable one according to your own needs.

There are not too much requirements on the use of the ordinary screwdriver, but it should be noted that the material of the screwdriver shaft and tip should not be too soft, otherwise it will occur deformation when applying too much force.

The screwdriver sets vary one to another, often found that 31 in 1 screwdriver set, 47 in 1 screwdriver set, etc. The screwdriver set generally includes a screwdriver handle and a variety of bits, thus the head of screwdriver can be changeable according to the use. Screwdriver handles come in all shapes and sizes, from plastic to aluminum alloy, extendable, and ratchet.

Electric screwdriver is higher in price than the manual screwdriver, but it is much more efficient and labor-saving.
