Carbon Steel 4*30*100 Car Wheel Lug Nut Cross Wrench

45# carbon steel construction with zinc surface treatment provides adequate strength and corrosion protection for emergency and light professional use. The four-socket cross pattern typically covers the most common passenger car and SUV lug nut sizes in a single tool, eliminating the need to carry multiple individual wrenches.

The wide cross layout also allows the user to step on one arm while pulling up on the other — effectively using body weight for additional leverage when dealing with stuck or over-tightened wheel nuts. The compact, symmetrical form stores easily in a boot tool roll or hanging on a workshop wall.

Available in standard socket size combinations (e.g., 17/19/21/23mm). 45# carbon steel with Zinc finish is standard; Chrome Vanadium (Cr-V) upgrade available for professional-grade durability. OEM/ODM customization supported for size combination and surface treatment.
