Frequently Asked Questions - RTD-10-50in.lbB Vevor

How to set torque on the Vevor RTD-10-50in.lbB torque screwdriver?

Hold the fixed part of the screwdriver with one hand, and with the other turn the collar clockwise to move the graduated ring. Adjust until the main and secondary scale lines match the desired torque value. Release the collar to lock the setting.

What does the click and vibration mean during tightening?

The audible click and vibration in the hand indicate that the tightening torque has reached the preset value. You should then stop applying force to avoid over-tightening.

Can I use this screwdriver in clockwise direction (right-hand tightening)?

No, this model is designed to work only in counterclockwise direction (anticlockwise). It is intended for tightening screws with left-hand threads or for specific applications where triggering occurs when unscrewing.

What bits are included with the RTD-10-50in.lbB model?

The kit includes 22 screwdriver bits in S2 and CrV steel, as well as a break bar. The bits cover various sizes and profiles for slotted, Phillips, Torx, etc. (see detailed list in the manual).

How to maintain the torque screwdriver?

After each use, reset the torque value to zero (minimum position). Never disassemble the tool as this may affect accuracy. Store it in a dry place, away from acids and corrosive gases. Use only suitable bits.

What is the accuracy of this tool?

The accuracy is ±5% of full scale (FS). For example, at 50 in·lb, the tolerance is ±2.5 in·lb. It is factory calibrated and should not be disassembled.

Can I use an extension or adapter?

Yes, you can install a break bar at the rear of the screwdriver if you need more leverage. For models RTD-10-70in.lb and RTD-20-70in.lb, specific adapters are provided.

How to know if the screwdriver is properly calibrated?

The tool is factory calibrated and does not require user recalibration. If you suspect a precision issue, contact after-sales service via www.vevor.com/support.

What are the essential safety precautions?

Read the manual carefully before use. Do not use the tool for striking or as a lever. Stop immediately upon audible trigger. Do not wear loose clothing that could get caught. Wear safety goggles if necessary.

Is this screwdriver suitable for DIY or only professional use?

It is suitable for both, especially for precise tightening of screws on precision instruments, printed circuit boards, or delicate mechanical assemblies. Its range of 10 to 50 in·lb makes it ideal for light to medium applications.

5 How To Use

Step 1:

Set the torque value of the screwdriver according to the torque required when fastener is tightened. When the torque value is preset, hold the hand part first the hand wheel with the other hand, and move it to the straight circle. Pres direction and then adjust the hand-wheel clockwise to make the linear scale. Let the value of the main scale line and the sub-scale line reach the required torque value, then release the adjustment hand-wheel and the preset torque v is completed.

Step 2:

According to the head form of the fastener, select the batch head from the accessory and insert it into the hexagonal joint of the screwdriver (if there is suitable batch head in the attachment, the batch head can be processed by The size of the hex joint is as shown in the above figure. Show).

Step 3:

Install the batch head of the corresponding specification on the screwdriver, align the bit to the fastener with the handle, and turn the

screwdriver until the tightening torque of the fastener reaches the set value, and the idling of the screwdriver occurs. At the same time, it is accompanied by obvious hand vibration, prompting to complete the operation.

Step 4:

If it is not used for a long time, adjust the tick mark to the minimum torque
