Table of Contents. The origin of screwdrivers dates back to a century when these tools were created in order to tighten newly-invented screws in engines of war and suits of armor.
The screws of that time were a sharp threaded needle with a slot cut in the head for tightening. As screws evolved, so did screwdrivers. This is because without the right screwdriver head, it would be virtually impossible to remove a specific type of screw.
However, not many things have changed about the screwdriver since the Middle Ages and the only innovations in the past several centuries have been in the material used and the shape of the drives and the handle designs.
Despite this or maybe, because of this the screwdriver remains one of the most important tools in the manufacturing and home improvement industry, click here for details. Most of us have heard of a few different types of screwdrivers but in reality, there is a wide range, containing dozens of different versions of drives, to choose from. Here are some of the most used types:. S lotted screwdrivers , which are also known as the flat head screwdriver, flat blade screwdriver, or straight screwdrivers, are the oldest forms of screwdrivers.
They are used on screws with a simple slot spanning the width of the screw, also called a slotted screw. These blades are flat-planed and come in different sizes to accommodate screws of the same varied sizes. The most common two sizes are the 5. They are the two types of screwdrivers found most often in home tool kits.
The slotted screwdriver also allowed for the invention of many different screwdrivers. High quality slotted screwdrivers have almost parallel tapered tips that help to grip the slot of a slotted screw tightly and prevent slippage. Cabinetmakers prefer to use slotted screws, as they take pride in aligning the slots. This makes their work look impeccably neat.
The Phillips screwdriver is also known as a crosshead screwdriver because of its cruciform head. However, in superior quality Phillips head screwdrivers, the tip is somewhat rounded. These screwdrivers are made to fit into screw heads which are made in the West and do not have sharp tips like slotted screws.
The Phillips screwdriver has an angled tip with thinner blades. This means that the screwdriver can be slotted deeper into the screw head without the risk of the screwdriver slipping out from the sides, which is a common issue with slotted screwdrivers. This deeper slot also means that a greater torque can be exerted on these screwdriver.
Because of this, Phillips head screwdrivers are used in almost every field as the most preferred kind of screwdrivers. The Pozidriv screwdriver is considered to be an upgraded version of the Phillips screwdriver. It was created to reduce the risk of the drives camming out when high pressure is applied to them. The Pozidriv screwdriver is characterized by four shallow lines radiating from the center. Its tip is smaller and blunter than that of Phillips screwdriver, and contains ribs among the blades.
This increases contact with the screw head, which means more turning force can be applied without the danger of the screwdriver slipping out. The Pozidriv screw and screwdriver system is incredibly efficient. It is also less likely to break the screw head or the tip of the screwdriver when the correct pressure is applied. These screwdrivers usually come in sizes from one to three. The Torx screwdriver is a trademarked screwdriver.
These types of screwdrivers were once popular in the security and manufacturing field, but have now become widely used in commercial fields as well.
This screwdriver features a blade shaped in the form of a recessed six-pointed star, but with rounded off sharp angles. This blade shape increases the contact area between the screwdriver tip and the screw head, and provides improved torque. Noise Level Idle.
