Tangent key withstands torsion in one direction only that's why two tangent keys are used opposite when the shaft is subjected to high impact torque.

Key for Transmission of Impact Torque
When transmitting torque from a shaft to a hub or vice versa, keys are frequently employed. Keys are typically utilized in conjunction with keyways, which are slots or grooves in the shaft or hub. These slots are used to keep the key in place and to prevent it from slipping out of place during operation.
Types of Keys
There are several different types of keys available, including Woodruff keys, feather keys, gib-head keys, and tangent keys. The type of key that is preferred for a given application is dependent on a number of factors, including the amount of torque that needs to be transmitted, the direction of rotation, and the type of machinery being used.
Tangent Key
The tangent key is a type of key that is frequently used in applications where a large amount of impact torque must be transmitted in both directions of rotation. This type of key is designed to fit snugly into the keyway of the hub and the shaft, and it is held in place by friction.
The tangent key is a relatively simple design, consisting of a rectangular or square cross-section and a tapered end. The taper on the end of the key allows it to fit tightly into the keyway, reducing the likelihood of slippage or movement during operation.
Advantages of Tangent Key
One of the primary advantages of using a tangent key is that it is capable of transmitting a large amount of torque in both directions of rotation. This makes it ideal for use in applications where the direction of rotation is likely to change frequently or where the amount of torque being transmitted is particularly high.
In addition, tangent keys are relatively easy to install and remove, making them a popular choice for a wide range of machinery and equipment. They are also relatively inexpensive, making them a cost-effective solution for many applications.
Conclusion
In conclusion, if a large amount of impact torque is to be transmitted in both directions of rotation, a tangent key is the preferred choice. This type of key is designed to fit snugly into the keyway of the hub and the shaft, and it is capable of transmitting a large amount of torque in both directions of rotation.
