What is a screw driver

It came into use during 15th century Europe and remains widely used worldwide today. The Philips screwdriver was introduced in the early 19th century and has since taken over as the most common screwdriver today. What does a Phillips screwdriver look like? Phillips screwdrivers and screws are easily recognized by their cross shape. While they are privy to the cam-out effect, it actually only does this when the toque limit has been passed.

So by camming out it actually extends the life of the tool and saves the screwdriver and screw from damage. This design is widely used in Europe, but not so common in America. They still cam out, but not as often as slotted and Phillips screwdrivers. Torx screwdrivers, often referred to as star tip screwdrivers, have been on the rise in popularity in recent years. Their 6 rounded lobes have a great number of benefits. These were invented in 19th century by Henry Phillips with an aim to introduce the power driven screwdrivers in most of the industries.

When you see these screwdrivers from the front, the tip looks like a cross sign. These types of screwdrivers also shows cam- out effect but it does purposely when the torque exceeds a limit while tightening up of screw which resist the damage of screwdriver profile and screw and clearly extends the life of the tool.

The pozidriv screwdriver, unlike Phillips screwdriver, has two cross sign which are offset at 45 degree angles. These are designed and widely used in Europe. The engagement of quite tapered square shape opening screw with the square protrusion, with no angle involved, neglects the cam-out effect, thus improve centering. Slight Taper shape at the front of the tool provides a good locking with the screw and thus makes it more comfortable for use.

These screwdrivers types were first used for industrial purpose by ford motor company, because these drivers speed up the production, reduce damages, and highly reliable. Torx screwdriver is becoming very common and often used by automotive technicians. Many times they are called as star tips by technician. This driver has a star shape tip with 6 rounded lobes. In fact, it can help you do more than just tighten screws.

If you ever find yourself without a hammer, flip the screwdriver around to use the handle as your hammer. There are two basic types of screwdrivers: Phillips, which has a sectioned tip shaped something like a cross, and flat or slotted, which has a single, wedge-shaped tip.

Flat-head screws withstand much more torque before the screwdriver slips, meaning they can tighten more than a Phillips-head screw.
