<p>If you are asked to name one of the most common of the hand-tools, we bet you will name the Screw Driver amongst one of them. Without any disagreement, the most common&nbsp;<a href="https://www.liveabout.com/cars-motorcycles-4688157">tool</a>&nbsp;on the planet—the jack-of-all-tools is the flat-head Screw Driver. Every hardware drawer has one or two in it. While it comes in many shapes, the concept remains constant - a flat-head with a wedge-shaped flat tip, used to tighten or loosen screws that have a straight or linear notch in their heads. There will be some sort of handle attached to a steel shaft that is flattened into a wedge shape at the tip. This flat tip is perfectly sized to fit into a screw with a straight head slot with a corresponding shape. This design has given it the common name - Slotted Screw Driver.</p>

<p>The Past of Minus Screw Driver</p>

<p>Early on during the early 15<sup>th</sup> century, the screws were used to join the pivot point of body-armours and fire-arms. Essentially, it was a Military hardware. It is believed that Minus Screw Driver was first invented in either Germany or France and is also known as Minus screw-puller. The Modern flat-head&nbsp;<a href="https://www.thoughtco.com/history-of-screws-and-screwdrivers-1992422">Screw Driver&nbsp;</a>was probably invented in about 1744 in England, and was known as a "turn-screw"—a type of bit used as an attachment in a carpenter's brace-and-bit tool. The hand-held version of the tool first appeared in the United States in the 1800s. And design wise, the only form of the tool was the flat-head for the next 130 years or so, when the Phillips&nbsp;head came into use, based on a patent by Henry F. Phillips.</p>

<p>The Minus Screw Driver is made of tough steel that will resist any kind of bending or twisting when applied to hard jobs. While earlier the tips used to be plain, today, the blade tip of Minus Screw Driver in Chennai will have been treated with a dark tip coating for improved visibility between the tip of the Minus Screw Driver and the head of the Screw. The handle is made of either wood, plastic, or metal with either a hexagonal, square or oval cross-section that allows better grip and ergonomics.</p>

<p>The modern Minus Screw Driver in Chennai workman's possession will be an evolved one. While the earlier types used to be a single piece set-up, today the Screw Driver in use will have a shank that can be removed and replaced. The shape and design of the handle allows a comfortable fit with indentations of the worker's hand. Hexagonal section at the base of the handle on some screw drivers comes in handy when one needs to increase the amount of torque to get the screw on or off. A Ring or open spanner is fixed to achieve this. Some Minus Screw driver in Chennai workman's inventory will have a fixed shank, but with removable bit heads. These are more used in lighter jobs.</p>

<p>Jack-of-all-Use</p>

<p>The Flat-head or slotted screw driver design cannot be termed as the best of the designs, but was the first, and because of this,&nbsp;we find countless things that require a flat-head Screw Driver to remove or install. Though the flat-head has been replaced by different types of screw heads like the Phillips head, square-drive heads, pozi-drive, and Torx-type heads, still we find the need to use a flat-head Screw Driver from time to time.</p>

<p>The flat-head Screw Driver is also one of the most used for various purposes other than it was originally intended for. It is often substituted for any number of other tools when they are not available. Many a times, we find the workmen will put a flat-head Screw Driver to work as a chisel, as a nail-puller, as a paint-scraper, as an awl, or as a small pry-bar. Many people who are experienced in using hand-tools at home, know that it is best to never throw an old flat-head Screw Driver away since it can often be ground down, bent, filed, or otherwise adapted into all kinds of practical uses around the house.</p>

<p>You must be careful&nbsp;<a href="https://www.liveabout.com/removing-a-stripped-or-otherwise-screwed-screw-281716">when leaving the tool's comfort zone</a>, however. Prying too hard can cause the end of the tool to snap off. Using it&nbsp;as a chisel and pounding on the end with a mallet may also cause the handle to snap into pieces turning it into a useless junk. That is perhaps the only time when you will need to throw it away.</p>

<p>How to Use as a Screw Driver</p>

<p>There are flat-head Screw Drivers in many sizes, so one must choose the which most closely matches the job we need to do with it—meaning the one whose blade best fits the screw slot. The slots in flat-head screws do not just require a wider tip as the size of the screw increases, it also needs to be thicker. Flat-head Screw Drivers vary in thickness proportionate to their width, which gives you an excellent grip in the slot of a screw. The principal drawback of a flat-head Screw Driver is that it is prone to slipping out of the screw slot, so choosing a Screw Driver that fits just right is key to correct use. The blade should fit fully down into the slot on the screw, with little, if any, wiggle room.&nbsp;This is just one of the many&nbsp;<a href="https://www.liveabout.com/hobbies-4688185">inexpensive tools</a>&nbsp;that you should have in your toolbox.&nbsp;Visit your nearby <a href="https://samsindus.probsoltech.com/shop">Hand Tools Dealers in Chennai</a> and ask for your toold </p>
