Torque angle gauges are specialized tools used to measure the rotation angle of a fastener during the tightening process. They are commonly used in automotive, engineering, and industrial applications where accurate torque tightening is crucial. Here's a brief overview of torque angle gauges:

1. Function:
• Torque Measurement: Torque angle gauges are designed to measure the rotational movement or angle of a fastener during the torque application process. They provide an additional measurement parameter beyond the torque value, allowing for precise control of the tightening process.
• Angular Measurement: The gauge typically consists of a graduated scale or protractor that indicates the rotation angle in degrees. The user can read the angle value as the fastener is tightened.
2. Usage:
• Attachment: The torque angle gauge is attached to the fastener being tightened, typically by inserting it between the torque wrench and the fastener or by using an adapter specific to the gauge.
• Tightening Process: As the torque is applied to the fastener using a torque wrench, the gauge records the angular rotation. The user can monitor the angle reading on the gauge to ensure that the desired torque and angle specifications are met.
3. Benefits:
• Accuracy: Torque angle gauges provide a more precise method of torque tightening by considering both the applied torque and the resulting angular rotation. This helps achieve accurate and consistent tightening, ensuring proper clamping force and preventing over-tightening.
• Torque-to-Yield Applications: Torque angle gauges are particularly useful in torque-to-yield applications where specific torque values and angles are required to achieve the desired clamping force.
• Quality Control: These gauges help ensure that fasteners are tightened within specified tolerances, meeting the required torque and angle specifications for safety and reliability.
• Versatility: Torque angle gauges can be used with different types of fasteners and torque wrenches, making them suitable for a variety of applications.

It's important to follow the manufacturer's instructions and specifications when using torque angle gauges to ensure accurate and reliable measurements. Proper calibration and regular maintenance of the gauge are also necessary to maintain its accuracy over time.

In summary, torque angle gauges are specialized tools used for measuring the rotation angle of a fastener during tightening. They provide an additional measurement parameter alongside torque, allowing for precise control of the tightening process. Torque angle gauges are valuable tools in industries where accurate and consistent torque tightening is essential for the safety and integrity of assembled components.
