21mm Heavy Duty Steel L Type Tire Wrench

Manufactured from 45# medium carbon steel with quench-and-temper heat treatment, the wrench achieves the hardness and toughness balance needed to withstand sudden impact loads during emergency roadside use without cracking or plastic deformation. The zinc and electrophoretic (E-coating) dual surface treatment ensures reliable rust resistance for long-term storage in vehicle tool kits under varying temperature and humidity conditions.

The 21mm socket size fits the most common lug nut dimensions on full-size SUVs and MPVs, including models from Toyota, Ford, Honda, and Hyundai. The compact L-shape stores easily in the spare wheel recess or under-seat tool storage, adding minimal weight and volume to the vehicle emergency kit.

Available in 17mm, 19mm, and 22mm socket sizes for other vehicle types. High-Chromium Vanadium steel option available for professional-grade durability. OEM/ODM customization supported for socket size, handle length, and surface finish.
