Premium CR-MO Steel: Crafted from high-grade Chromium-Molybdenum (CR-MO) alloy steel, this 20mm deep impact socket outperforms standard chrome vanadium in strength and toughness. The CR-MO material resists cracking, rounding, or deformation under heavy torque from impact wrenches, making it ideal for automotive repairs, industrial machinery, or construction tasks 6-Point Anti-Slip Design: 6-point hex design maximizes contact with fasteners, eliminating slippage and stripping even under extreme torque. Unlike 12-point sockets, this 20mm impact socket ensures a secure fit on worn or rusted bolts, perfect for high-vibration jobs like truck repairs, motorcycle maintenance, or heavy equipment disassembly. Engineered for precision, it protects both your tools and hardware Laser-Etched Size Markings: Featuring permanent laser-etched markings, this 20mm deep socket allows instant size recognition in low-light garages or cluttered workspaces. The wear-resistant labels won’t fade over time, unlike stamped or painted markings. A must-have for mechanics and DIYers who value efficiency during repetitive tasks with 1/2" drive tools Coating for Rust Resistance: Protecting against corrosion, oil, and moisture, the phosphate-manganese coating extends this 20mm impact socket’s lifespan in humid workshops, outdoor job sites, or marine environments. Compared to uncoated sockets, it reduces rust-related failures by 70% and maintains smooth operation even after years of heavy use Compatibility & Professional-Grade: Designed for mechanics, contractors, and DIY enthusiasts, this 20mm socket fits all standard 1/2" impact wrenches, ratchets, and torque tools. Its deep-well design securely grips long bolts on engines, trailers, or agricultural machinery. SAE-certified dimensions ensure vibration-resistant performance, making it a versatile upgrade for any toolbox MTO 1/2" Drive 20 mm Deep 6 Point Impact Socket, Chrome Molybdenum Steel
