Mechanical torque wrenches are trusted tools in automotive workshops, engineering units, and industrial projects where accuracy matters. At Delta Imports, we bring some of the best precision products in Bangalore, India, including high-quality torque wrenches trusted by professionals across the country. If you're new to torque tools or planning to buy torque tools in Bangalore, this clear and beginner-friendly guide will help you understand exactly how to use a mechanical torque wrench the right way. Let’s get started. 

Step 1. Get Familiar With the Tool 

Before using the wrench, take a moment to understand its parts:

● Main scale

● Micrometer scale

● Lock/unlock mechanism

● Drive head

● Ratchet head

Knowing these parts helps you set torque correctly and use the tool more confidently.

Step 2. Set the Correct Torque Value 

Every job requires a specific torque value. To set it:

1. Unlock the bottom of the handle

2. Rotate the handle to match your required torque value

3. Lock the setting again

Correct torque prevents under-tightening (which causes loosening) and over-tightening (which can damage components). Both of which can cause serious mechanical issues.

This step is especially important for anyone working with precision products. 

Step 3: Attach the Correct Socket

Choose a socket that fits the bolt or nut properly.

● Choose a socket that fits perfectly

● Push it onto the drive head firmly

● Make sure there’s no movement

A proper socket ensures accurate torque transfer and prevents slipping.

Step 4. Position the Wrench Correctly

Your grip and position affect torque accuracy.

● Hold the wrench at the end of the handle

● Keep the wrench aligned straight with the bolt

● Maintain a steady posture

● Ensure the wrench and fastener are in a straight line.

Good positioning ensures that the torque reading is accurate — a critical need in industries that rely on precision products. 

Step 5: Start Tightening Slowly

For mechanical (click-type) torque wrenches:

● Apply steady pressure.

● Continue turning until you hear a clear “CLICK.”

● Stop immediately, this click means your set torque has been achieved.

This step is crucial in tasks requiring high accuracy, such as engineering, manufacturing, and service industries.

Step 6: Double-Check the Tightening

If required, recheck the applied torque:

● Do not tighten beyond the click point.

● If unsure, loosen the fastener and re-tighten using the same torque setting.

This ensures consistency in mechanical work. 

Step 7: Maintain & Store the Wrench

To extend the life and accuracy of your tool:

● Reset torque to zero after use.

● Clean the tool with a dry cloth.

● Store it in the case provided.

● Keep it away from moisture and heat.

Regular maintenance ensures long-term accuracy, especially for professionals.

Why Using a Mechanical Torque Wrench Correctly Matters

Using the tool properly helps you:

● Prevent equipment damage

● Avoid over-tightening or breaking fasteners

● Improve safety

● Maintain accuracy in mechanical tasks

● Increase product life and reliability

For industries or individuals who rely heavily on precision, choosing the right torque tool becomes extremely important.
