Screw drivers are an amazing tool that are used to tighten or loosen screws of different head patterns. A screwdriver usually has 2 major parts, a handle which is held by the person using it, and a shaft with a tip. A multipurpose screwdriver set has so many types of screw drivers that vary in their size and the shape of head. Generally, we use 3 major types of screwdrivers:-
1. Simple manual screwdriver
These screwdrivers are used with manual mechanical force and have a simple design
2. Electric screwdriver
It is an electric tool which is used when power is required to loosen or tighten the screws. It looks like a drill machine and makes the process of screwing/unscrewing almost effortless.
3. Precision screwdriver set
These screwdrivers are used to tighten or loosen relatively small fasteners that require more precision to be used.
How to use
For using a screwdriver, it should be held with the handle. Choose a screwdriver with the desired shaft tip based on the screw that needs to be tightened or loosened. Then, fit the tip into the screw, and rotate it clockwise to fasten it, and anti-clockwise to loosen it. Electric screw works in the same way, just that it has a button which needs to be pressed for rotating the shaft.
Common applications
1. Dismantling some electronic devices for repair purposes.
2. Changing old rusted screws.
Safety Measures to follow
● Do not use a bent or damaged screwdriver.
● Don’t apply excessive pressure while turning the screws.
