Screwdriver……………….

I was travelling in local train in second class compartment. Group of 5/6 people were targeting a guy; they said tera screw dhila hai thight karna padega.

It made me smile with myself; I just wondered what word dhila screw denotes?

A person with low intellect, lack of maturity is generally term dhila screw .The group got down at Dockyard  road station and what come to my mind  may not be relevant but thought let me share with you……for information .

Archimedes is considered to have invented the screw in the third century B.C.  though, his invention was designed to transfer motion rather than to fasten.

Metal screws and nuts seem to have been used as fasteners in the fifteenth century.

Woodworkers were using hand screwdrivers in the early 1800s, and they became more common after 1850, when machines made the automatic production of screws possible.

Later, the uses for screws and screwdrivers expanded to the area of machinery and furniture construction.

As the design of the screw itself became more refined and more useful, screwdrivers become a common and necessary tool.

There are perhaps thirty different types of screwdrivers available today in a variety of sizes, all with different purposes and all designed to fit into special screws.

In the early 1900s, a new form of the socket screw that featured a cruciform shape was invented and patented by Henry F. Phillips. His creation resulted in the birth of the classic Phillips screw and its corresponding Phillips screwdriver.

Screwdrivers are distinguished from each other based on their tip.The oldest and most common type of screwdriver is the slotted screwdriver, which fits a screw with a single slot in the head of screw with drive.

The tip of the screwdriver should completely fill the slot of the screw you’re driving or removing.

If the tip is too narrow, there will be considerable loss of leverage while driving, which means you’ll have to use more muscle to drive the screw.  Also, you risk stripping the screw and bending the tip of your screwdriver.

If the tip is too wide, you risk damaging the surface you’re screwing into.

If the tip is too thick, the blade won’t fit in the screw slot and will just slip out as you’re driving. 

There are cordless Screwdrivers & are more efficient than the manual screwdrivers.

And have several advantages over their corded counterparts.

Perhaps the most obvious advantage of cordless screwdrivers is their portability. 

They spare the user’s wrist & eliminate some of the fatigue that is associated with driving every screw by hand.

Another advantage is flexibility as they can be used in a number of different position & situations.

The biggest mistake people make when using a screwdriver is using the wrong kind for the job.

I am not a technical person per see still I shared with you about Screwdrivers.

Word of caution, few corrupt minded people have used the Screwdrivers to break open the houses, also as instrument to kill a person out of one’s frustration.

Do not keep Screwdrivers in open place & within the reach of negative bias persons. It is a double edge sword.

There are many interesting Screwdriver Stories, some time I shall share with you the same.
