Different Types of Torque Tools

Consistency, accuracy and reliability are the cornerstones for a successful, fast and error proof manufacturing line. Torque wrenches and drivers are crucial for reaching these goals. These tools can significantly increase output numbers, speed up workstations and reduce worker fatigue.  We will go over the basics of the torque tools.

What is a torque wrench?

In simple terms a torque wrench is a tool used for fastening screws to a set torque value. A torque wrench is a tool used to apply a specific amount of torque (rotational force) to a fastener, usually a nut or bolt. It's essential when tightening components to exact specifications, which helps avoid over-tightening (which can strip threads or damage parts) and under-tightening (which can cause failure or loosening during operation). 

Analog and digital torque wrenches

There are a few different types of torque wrenches that use different methods of reaching its set torque value. The most common type of these is the click type torque wrench which makes a clicking sound when it reaches its torque value, this is found mostly in the DIY and automotive space. There is also the beam type torque wrench which has no moving parts and instead uses a bending beam and a pointer to indicate the torque value. In that same vein there is the dial torque wrench, which uses an analog dial to indicate the amount of force you are putting on the screw or bolt. Towards the higher end of torque wrenches you’ll find digital torque wrenches which can make a noise when you hit your target value and display your torque on a screen that is either attached to the wrench or nearby on a computer screen. The benefit of digital wrenches is it allows you to accurately track data that you normally wouldn’t be able to see without manually entering everything into the computer.

What is a torque driver?

A torque drill, also known as a torque-controlled driver, is a power tool designed to drive screws and fasteners with precise, adjustable torque output. Unlike standard drills, which focus primarily on speed and power, torque drills allow users to set a specific torque level to ensure consistent fastening without over- or under-tightening. This makes them ideal for applications where repeatability and quality control are essential, such as in manufacturing, electronics assembly, or automotive production. Many torque drills feature built-in clutches or electronic shut-off systems that stop the tool once the desired torque is reached, helping prevent damage to components and improving overall process reliability.

Drills/Drivers

Moving onto torque drills/drivers, there are a few different levels to what they’re capable of doing and what roles they are made to fill. The most basic of the bunch being the stand alone tools that don’t require a separate computer. These tools are great for smaller operations that don’t want to purchase an expensive controller system just to make the tool run properly. They can have a few different mechanisms to precisely hit their torque targets, one of the ways is a built in clutch which can be preset to your specific torque value. This uses a spring type clutch to alert the system when your value has been reached and shut the tool off, usually paired with a light or a sound to let you know that you hit your preset value. Another way tools can sense they have reached their value is through current-controlled systems which use electricity to read the stress on the motor which is directly related to the amount of torque it’s applying. There is also a type called a pulse torque tool which instead of sending a constant stream of electricity or air to the tool, it sends a pulse of power until it reaches its target value and will then shut off on its own. We go into more details about these types of torque drivers and others in another blog. If you’d like to learn more click here.

Controllers

If a stand alone torque driver isn’t enough for your needs or you’re looking to upgrade your current driver in order to get more data and quicker adjustability then getting a tool and controller set might be right for you. Controllers are able to manage several tools at a time, collecting data and sending it to a main system that allows floor managers to see real time inputs like how accurate the tools have been, how long it takes to finish fastening one screw and the entire assembly and other great data which all helps in speeding up production, making sure everything is working as it’s supposed to and finding any bottlenecks that cause issues in production.

OGS

Taking it up a step from just a controller you have Operator Guidance systems (OGS).

An Operator Guidance System (OGS) is a digital tool designed to provide real-time, step-by-step instructions to manufacturing or assembly line workers during their tasks. It guides operators through each stage of a process using visual aids, integrated controllers, touchscreens, indicators, or even augmented reality, ensuring that complex or variable work is done accurately, consistently, and safely. OGS can display part diagrams, fastener torque values, work instructions, and alerts based on sensor input or system feedback. Often integrated with MES (Manufacturing Execution Systems), OGS helps reduce training time, minimize human error, and enforce standardized procedures, making it especially valuable in high-mix or quality-critical environments.

MES

As stated in the previous paragraph Manufacturing Execution Systems (MES) often integrate OGS into their system. The difference between the 2 is OGS is made for a specific operator work station and is more localized while MES is meant to be used on the entire assembly line or manufacturing floor allowing for all real time data to be reviewed and checked for inconsistencies and issues in the manufacturing process.

There are many differences to torque drivers and their applications in manufacturing, one type of tool might not be what you need but another can be exactly what you’re looking for.
