Screwdrivers

Invented more than two thousand years ago, the screw has been used both as a simple machine and, more commonly now, as a fastener to hold two objects together. The latter usage is so widespread and universal that screws and screwdriver tools remain ever-present in every mechanical aspect of our modern lives. A simple and yet versatile fastener, the screw has been modified for different workspaces and work materials. Each screw can be divided broadly into two parts the shaft and the head. The shaft of the screw is a threaded cylinder that may or may not be tapered. The head allows the screw to be rotated, so it may be tightened or loosened as desired with a hand screwdriver.

The screw head comes in a variety of shapes and sizes as well as drives, each for a different application. Screwdriver sets are essential tools since they provide versatility required to tackle the wide utilization of screws in various home or work scenarios. Whether it's a manual hand screwdriver or a battery-powered electric one, screwdriver tools must manipulate torque to drive screws into any surface. Although screwdrivers are designed explicitly for turning screws, they often used as improvised substitutes for pry bars, levers, and hole punches, as well as other tools. While screws have been around for some millennia, the indispensible screwdriver is a new invention dating back to the late 'Middle Ages'.
