Torque Lock

Torque lock refers to a condition in which a fastener, such as a bolt or a nut, becomes stuck or locked due to excessive torque or tightening force. This can happen when the threads of the fastener bind or seize, preventing it from being easily loosened or tightened.

Torque lock can occur for various reasons, such as over-tightening, corrosion, or improper lubrication. When torque lock happens, it can be challenging to remove the fastener without causing damage to the surrounding components.

To prevent torque lock, it is important to follow proper torque specifications and use the correct tools and techniques for tightening fasteners. Additionally, applying an appropriate lubricant can help reduce friction and prevent binding.

If torque lock does occur, there are several methods that can be used to release the stuck fastener, such as applying penetrating oil, using heat to expand the metal, or using specialized tools like impact wrenches or torque multipliers. However, it is important to exercise caution and follow proper safety procedures when attempting to remove a torque-locked fastener to avoid injury or further damage.
