What is an Electronic Torque Screwdriver?

For assembly lines & production facilities getting the right tool for the job is essential. Under-tightening or over-tightening components can lead to catastrophic results. This is where electronic torque screwdrivers come into the picture. Sure you've heard of a screwdriver, maybe even a torque screwdriver, or an electric screwdriver. But what what exactly is an Electronic Torque Screwdriver? And why is it needed for assembly?

Most importantly, these screwdrivers will inserts screws or bolts with a specific torque (tightness). If the screw is too loose, it may fall out, cause the part to disassemble, and could even cause another component to break. If it's too tight, it can snap or cause components to break, or not have enough play.

Some of these electric screwdrivers will have adjustable torque. Usually there's a torque range that the screwdriver can operate within, and it can be adjusted anywhere within that range. Many of the Electric Torque Screwdrivers are extremely precise, and will operate within a tiny margin of error.

You'll find some models are ESD (Electro Static Discharge) Safe. This makes them great for assembling electrical components like computers or smartphones.

Many use brushless motor, which is cleaner and lasts longer. These could be great for assembling equipment that needs to be sterile.
