You can't imagine the world without nuts, bolts and screws. The thing that fastens them all together is a screw driver. It one of the simplest things invented yet has many useful and essential usages. Without the screwdriver, our world will fall apart and we won't able to screw it back together. With the evolution of technology, screwdrivers have evolved too. There are so many types of screwdrivers present in the market today. Getting the right screwdriver for yourself is a must if you want to keep your workflow tight. Let's have a look at what you can get in the world of screwdrivers.
Presently, there are two types of screwdrivers on the modes of operation. One is the plain old screwdriver that we used to fasten screws using the torque generated by our hands. The other is the electronic screwdriver that generates torque and fastening using the power generated by a small electric motor. While the former can be used for home and office requirements, the latter is used for commercial purposes.
Too often it happens that screws are either fastened more than what they should have or left loose. In both cases, theirs is a greater risk of failure as an over tight screw exerts more pressure on the thread and may lead to fatigue and an under tight screw has more fluctuation in stress load and may fail sooner than the former. In both case, we need to fasten screws to the right amount to make sure they stay intact for longer periods of time and under extreme circumstances. For this, the best option is to use auto screwdriver machines. What they do is they stop as soon as the screw reaches the critical level of fastening required.
Auto screwdriver machines are easy to use and often work on batteries which are rechargeable. They not only offer precision but also offer speed and agility a huge time saver in working conditions.
Automatic screwdrivers also come in different tips which you can choose according to your preference
●Flat head: one of the most commonly used screwdrivers in India is the flathead screwdriver. It is used for screwing into soft materials. It needs screws with a straight slot head. Make sure you are getting a screwdriver that's tip is as wide as the slot of the groove.
●Cross Head: Philips screw driver or more commonly called crosshead screw drivers have sizes – number zero to three. Number two is the most common one and is used in most of the places. Like the name suggests, cross headed screw drivers are the ones with cross headed slot head.
Torx: Torx screwdrivers are relatively uncommon, part of the reason is their shape a star fish shaped fish with rounded corners. Torx is mostly used in the car industry and home appliances where a much greater force is required to camp the screw and nuts together.
