- Advanced mechanism and flexible use: 72-tooth ratchet gear delivers precise adjustments with only a 5-degree swing in tight spaces. The 180-degree flexible head pivots to bypass obstacles, expanding reach in awkward areas. - Comprehensive set and portability: includes 5 double-ended wrenches (8 mm to 19 mm) stored in a sturdy carrying case for protection and easy transport. - Design for tight spaces: compact, short build and handle improve maneuverability and comfort when access is limited. - Durability and craftsmanship: crafted from chromium-vanadium steel (Cr-V) for high strength, wear resistance, and corrosion resistance; built for demanding tasks and long-term reliability. - Practical use scenarios: perfect for bicycle maintenance in cramped frames (derailleur and brake bolts), automotive engine bay work where space is restricted, and furniture assembly or plumbing tasks in tight corners under sinks or panels.
