Cranked extension wrench set includes 1/4 inch, 3/8 inch and 1/2 inch square drive adapters, plus a 1/4 inch drill drive adapter, increasing versatility and compatibility with your tools. The cranked extension wrench features a slim profile: 37 cm long and 1.8 cm thick, allowing use in tight spaces and providing greater flexibility when using. High-quality material: made of carbon steel with a robust structure and a chrome-plated surface. Corrosion-resistant, rust-proof, with a shiny finish, high precision and good stability. It also has a zero-degree rotation arc and a built-in high-performance special chain, which saves power and increases efficiency. High efficiency and energy saving: designed for working in tight spaces and enabling the free movement of your ratchet wrench. It helps you easily loosen hard-to-release nuts or screws, so you can complete tasks faster and save time and energy. Non-slip handle: a plastic protective cover on the outside of the wrench provides a comfortable, ergonomic grip and prevents your hand from slipping during use, making it suitable for long-term use. Use scenarios: - Automotive repair in cramped engine bays or under dashboards. - Bicycle maintenance in tight frame areas or near the crankset. - Furniture assembly or cabinet installation in restricted spaces where reach matters.
