Steelman 99427 17mm Convex Head Lug Bolt Impact Socket for Mercedes Benz

The Steelman 99427 is a specialized 1/2-inch drive impact socket engineered specifically for Mercedes Benz vehicles equipped with unique "flower head" lug bolts. This professional-grade deep well socket prevents the damage that standard hex, star, or spline sockets can cause to Mercedes' distinctive convex lug bolt design.

Key Features:

• Mercedes-Specific Design: 17mm convex head profile fits "flower petal" lug bolts precisely without rounding or damaging bolt heads
• Deep Well Construction: 3-inch socket length provides extended reach for recessed lug bolts commonly found on Mercedes wheels
• Impact-Rated Durability: Forged chrome-molybdenum (chromoly) steel construction with black oxide finish withstands high-torque impact tools
• 1/2-Inch Drive: Universal compatibility with all 1/2-inch drive impact wrenches, ratchets, breaker bars, and air tools
• Secure Attachment: Detent ball hole ensures positive engagement with impact drivers and prevents socket detachment during use
• Corrosion Resistant: Black oxide protective finish resists rust and extends tool life
