Hex Key
A hex key tool, also known as an Allen wrench, is a small, L-shaped tool with a hexagonal head that is used to tighten or loosen hex bolts and screws. The hex key tool is typically made of hardened steel and comes in various sizes to accommodate different hex bolt sizes. The hex key tool is designed to fit into the hexagonal recess of the bolt head, allowing the mechanic to apply torque to the bolt or screw. The L-shaped design of the tool allows for easy access to tight or hard-to-reach areas, such as inside the engine compartment or under the vehicle. The hex key tool is commonly used in automotive repair and maintenance for tasks such as removing or installing engine components, adjusting brakes, and tightening various bolts and screws. Proper use of the hex key tool is critical to prevent damage to the vehicle and ensure proper torque is applied to the bolt or screw.
