Wera Safe Torque A2 Set

If you ever want to splurge on a good torque wrench, here is a good candidate. Prior to this, I have been using the same trusty Giant Torque Wrench for nearly 10 years. It is still working, but it has never been calibrated in those 10 years. Besides, it is always nice to get new tools!

The Wera Safe Torque wrench has many unique features that seem interesting to me. Check it out below!

Wera Safe Torque A2 set. There are other sets that include different types of tool bits.

Top row shows the feature where you can engage or disengage the torque limiter.

This set comes with these tool bits, which should be enough to cover most of the use cases for bike maintenance.

Comes in a neat little hard case!

You can stick the velcro on a vertical surface, if you wish to mount the hard case on the wall.

It even tells you which surfaces are suitable for sticking the velcro strip, if you want to attach the tool set to the wall.

A1 and A2 has a different default connector at the head, depending on which type you use more often.

This explains how to use the sliding sleeve to activate or deactivate torque control.

Torque wrench set neatly packaged!

Sockets are colour coded, and removed from the base by twisting them.

This graphic shows how the sockets can be removed from the base.

At the end of the torque wrench, there is a section that can be pulled out.

To set the torque, first pull out this section.

Then, rotate the entire lower half of the handle so that the torque value goes to your preferred setting. 

It is adjustable to within 0.1 Nm. Once done, push back the end of the handle to lock this setting.

This green sleeve near the head can be slid between the ON and OFF position.

When slid towards the OFF position, it means that torque control is off. The torque wrench will not click when it reaches or exceeds the set torque.

The green knurled wheel on the head can be rotated to switch the ratcheting direction clockwise or anti-clockwise.

Here is the default connector for the A2 type, which is a female socket.

This allows the tool bit to be inserted directly to the tool head.

On the other hand, if you want to use a socket, you need to put on the adapter first.

The adapter converts it to a standard 1/4 inch tool bit, for a standard socket.

Whole set can be kept neatly inside this hard case, which is awesome!

Although I don't need to use a torque wrench often, it is a pleasure when I get a chance to use it, as the Wera Safe Torque A2 set is such a well built tool.

One downside of this torque wrench design is the click sound that it produces when it reaches the set torque. This is due to the mechanism slipping as designed, to prevent excessive torque from being transferred to the tool bit.

However, this slippage sound and feeling is similar to something breaking, instead of the gentle click that I was used to on other torque wrenches. It is rather disconcerting if you are not used to hearing this sound.

Otherwise, all other features such as the torque adjustment work very well.
