This tool gives you more control than old wrenches. You do not need to guess or use a needle gauge. The digital screen shows numbers you can read easily. You know when you reach the right torque.

Note: Many digital torque wrenches give you lights and sounds as feedback. Some advanced models can connect to computers for tracking data.

Some people believe myths about these tools. Some think digital torque wrenches are not as accurate as mechanical ones. But new digital models are often more precise. Others say you must recalibrate after every drop or warm up the tool. These things are not true for most models.

How It Works

A digital torque wrench uses sensors to measure force. When you turn the handle, the sensors check the torque. The data goes to the digital screen. You can set your target torque before you start. The screen updates as you work. When you hit your target, the wrench beeps, vibrates, or flashes a light.

• Sensors check torque right away.
• The screen shows the torque you use.
• You can set a target, and the wrench will alert you.

Most digital torque wrenches are very accurate. You can see how accurate they are in this table:

These wrenches do not need batteries or electronics. You can use them in rough places without worrying about power. But you must listen for the click every time. If you miss it, you might tighten the bolt too much. Mechanical wrenches need to be checked often to stay correct. There is no digital screen, so you must rely on your touch and hearing.

Beam-Type

Beam-type torque wrenches have a simple design. You watch a pointer move along a scale as you turn. You must read the scale by yourself. This type does not use batteries or electronics. It is a tool that is dependable and costs less. But you need to look at the pointer closely and read the numbers. This can be hard if it is dark or the space is small. Here are some main differences between digital and beam-type wrenches:

• Accuracy: Digital torque wrenches show the exact torque on an LED screen. Beam-type wrenches make you read a scale, which can cause mistakes.
• Ease of Use: Digital models let you set the torque and alert you with sound or vibration. Beam-type wrenches need more focus and you must read them by hand.
• Cost: Beam-type wrenches cost less than digital models. You get fewer features, but you save money.
