Introduction:

Designs of screwdrivers:

As the name suggests, screwdriver is a tool that is used for inserting, removing, tightening, or loosening screws. Screwdrivers are available in many different shapes and sizes. The sizes range from very tiny to extremely large depending upon the size of the screws and their uses. The skill of the worker lies in using the appropriate screwdriver, as wrong screwdrivers can significantly damage the work due to excess force used in tightening. A screwdriver consists of a tip, which is used to rotate the screw, which provides support and firmness to the screwdriver. The best tip is the one, which neatly fits into the head of the screw. Handheld screwdrivers are also provided with handles that provide firm and a tight grip to the user. The tip of the screwdrivers can be rotated manually, or by an electric motor. There are also many different types of screw heads of which the most popular are the Allen or hex, slotted, and Phillips. Some types of manual screwdrivers also have ratchet action making clockwise and counter clockwise rotations of the screw possible very effectively for tightening and loosening the screws. Some advanced forms of screwdrivers also have detachable bits, which allow the main body to accommodate different sized and different shaped bits. Such screwdrivers most commonly run on electric or power motor. Other design that is also gaining popularity is the spiral ratchet, which is again a manual screwdriver. Apart from these basic designs many more models are also available for your own special needs. New and innovate designs are also coming up to give this simple tool extraordinary edge over all other drilling tools.
