The Different Types of Screwdrivers and Screws

Drawer full of various screwdrivers imageIt’s hard to even begin to comprehend how much standardized fasteners and hand tools have changed the modern world. Let’s dig a bit deeper and I’ll share with you the things you need to know when it comes to understanding screwdrivers, screws, and the various screwdriver bits you can use to help you get jobs done.

Screwdrivers have been around since the 15th century but didn’t really become quite so commonplace until the industrial revolution. With the invention of automated industrial processes the creation of reliable & uniform screws become possible.

Until the automation of screw manufacturing each screw had to be handmade and that made each screw unique and for a specific application. Once screws could reliably be manufactured to exacting specifications then the screwdriver would become an integral part of every tool chest.

I’ll start with ones you’re most likely to need in everyday use both on the job or around the home. To keep things clear, I’ll show you both the screwdrivers and the screws in order to help you understand more.

There’s a lot of different fasteners out there, but basically only a relative few that you’ll commonly need to be concerned with. Screws have specific applications depending on the type of engineering they are a part of. Most types are made to either deal with high torque, resist over tightening of screws, or made specifically to resist being removed or being tampered with.

Many tool sets will have just the basic types of screwdrivers for the most common applications while a few others will have a wider range of types specifically for electronics.

I recommend that unless you’re only needing a specific type of screwdriver for now, I recommend you pick up the following in order to be prepared for most common types of fastener removal or installation:
