1. Torque Wrench:
A torque wrench is the primary tool used for tightening bolts to a specific torque value. It is designed with a mechanism that allows the user to apply a precise amount of torque. There are two main types of torque wrenches:
- Click Type Torque Wrench:
This type of torque wrench produces an audible click when the desired torque value is reached. The user stops applying force once the click is heard, ensuring the bolt is tightened to the correct torque.
- Digital Torque Wrench:
Digital torque wrenches provide a digital readout of the applied torque value. They are more accurate and can often store and recall torque values for various applications.
2. Torque Screwdriver:
Torque screwdrivers are similar to regular screwdrivers but incorporate a torque-limiting mechanism. They are used for tightening smaller screws and bolts where precise torque is required.
3. Impact Wrench:
Impact wrenches are power tools that use a hammering motion to tighten or loosen bolts. They are commonly used in automotive repair and construction work. Impact wrenches typically have adjustable torque settings to ensure proper tightening.
4. Hydraulic Torque Wrench:
Hydraulic torque wrenches use pressurized hydraulic fluid to generate high amounts of torque. They are commonly used in industrial applications, such as pipeline construction and heavy equipment maintenance.
5. Pneumatic Torque Wrench:
Pneumatic torque wrenches use compressed air to generate torque. They are often used in assembly line operations and other industrial applications where speed is essential.
6. Electronic Torque Wrench:
Electronic torque wrenches combine the features of digital and torque wrenches. They provide precise torque measurement and control and often have data logging capabilities.
7. Manual Torque Wrench:
Manual torque wrenches are simple tools that rely on the user's strength and judgment to apply the desired torque. They are commonly used in situations where precision is not critical.
It's important to select the appropriate tool based on the required torque value, bolt size, and application to ensure proper and safe tightening of bolts.
