Aflojatadores

Aflojatadores is a term used in Spanish and Portuguese-speaking contexts to describe tools, agents, or methods designed to loosen fasteners, joints, or assemblies that have become tight, corroded, or seized. The concept covers both mechanical devices that apply torque or impact and chemical substances that reduce friction and bonding.

Mechanical aflojatadores include impact tools, torque wrenches set to reverse rotation, extractor kits, and dedicated devices that apply controlled force to unscrew or separate parts. These devices are used when standard turning forces fail or risk rounding bolts, studs, or threaded connections.

Chemical aflojatadores encompass penetrating oils, rust removers, and lubricants formulated to seep into threads and crevices, soften corrosion, and lower friction. They are commonly applied in automotive repair, machinery maintenance, and construction.

A typical procedure involves identifying the fastener type and material, selecting the suitable aflojatador, cleaning the area, applying the agent or tool, waiting for penetration or cooling, and then reattempting to loosen with appropriate force. In some cases, heat, lubrication, or alternate methods are required, and safety considerations include flammable solvents, skin and eye protection, and ventilation.

Limitations include very stubborn corrosion, damaged fasteners, or heat-sensitive components, which may require professional intervention or different techniques. See also penetrating oil, loosening torque, fastener extraction.
