Product Overview
The W40270 cross-shaped lug wrench (also known as a spider wheel wrench or 4-way tire iron) is a heavy-duty automotive tool built for efficient wheel and tire service. Forged from chrome vanadium (CR-V) steel and finished with complete heat treatment, it delivers the ideal balance of surface hardness and toughness. With a 400 mm overall span and integrated 17, 19, and 21 mm socket heads plus a 1/2-inch drive square on the opposite end, it is engineered to handle passenger-car and light-truck wheel nuts in both roadside and workshop environments.
Key Features
-
CR-V Steel Forging: Drop-forged chrome vanadium construction provides superior strength and long service life under high torque.
-
Heat-Treated for Performance: The full heat-treatment process ensures excellent hardness while retaining the flexibility needed to resist cracking or snapping.
-
Multi-Size Coverage: Built-in 17 mm, 19 mm, and 21 mm heads cover the most common lug-nut sizes found on global vehicle platforms.
-
1/2-Inch Drive Compatibility: The square drive end accepts standard 1/2″ ratchets, breaker bars, impact extensions, or torque accessories for added leverage.
-
400 mm Working Length: The generous cross span supplies the mechanical advantage required to break loose stubborn, over-tightened wheel bolts.
