High Carbon Steel Black Oxide Coated L‑Shape Tire Wrench

An L‑Shape Tire Wrench, also known as a tyre socket spanner or wheel nut wrench, is a mechanical hand tool with an L‑shaped one‑piece forged structure consisting of a socket end and an extended lever arm. This design allows the long lever arm to generate amplified torque for loosening and tightening wheel nuts during tyre replacement and routine vehicle maintenance.

L‑Shape Tire Wrenches are manufactured from high‑carbon steel or alloy steel, offering  torque resistance and structural stability. The alloy steel variants deliver  mechanical performance for heavy‑duty garage and frequent workshop operations. Key dimensions are configurable, including socket opening size, lever arm length and bar thickness, to match different wheel nut specifications of passenger and commercial vehicles.

Multiple surface finishing options are available to meet diverse anti‑corrosion demands, including black oxide, zinc plating, phosphate coating, electrophoresis and Dacro coating. Each treatment improves rust resistance and prolongs service life under harsh working environments. It is widely adopted as onboard emergency equipment for private vehicles and standard hand tool within auto repair shops, garages and automotive after‑market supply chains.
