Types of Screwdriver

Screwdrivers come with different types of bits for all kinds of uses.We can easily get confused and messed up with all these names and functions.To avoid this kind of embarrassment, let’s have a quick look at 5 basic types of screwdrivers.

1. Flat Head screwdrivers

It is one of the most tradition and common-seen types, which is also known as straight, slotted, or flat blade.

2. Phillips Head screwdrivers

The tip of this kind of screwdriver looks just like a cross. The design of Phillips head is to “cam-out”, which means they are designed to slip out of the screw, so you don’t over-tighten them.

3. Robertson screwdrivers or Square Head screwdrivers

Robertson’s design depended on the corresponding square shape on the top of screw. As the screwdriver was rotated, it was far less likely to slip out of place and the process moved a lot faster. Because the driver is self-centering, only one hand is needed for rotation, and this also makes it easier to use than the traditional flat head one.

4. Torx Head screwdrivers

Torx Head comes in variety of sizes and tips such as T8, T10, T15, T25 etc., and as the number goes up, size of the tool tip increases.

5. Hex screwdrivers/ Hexagon Head screwdrivers

To differentiate the torx and the hex head, you just need to find the shape with 6 straight lobes, like hexagon.

This kind of type is mostly used to fasten bolts rather than screws.
