- Material and durability: The wrench set is made from CR-V chrome-vanadium steel with hardness up to HRC56, offering good toughness and wear resistance. - Coated finish and practicality: The surface is coated with colored plastic, providing water resistance and rust protection. The finish is precise and attractive, fully aligned with specifications and designed for efficiency and practicality. - Flat head design: The flat head is optimized for turning deep-hole screws with a large contact area. This design is convenient and fast, helping reduce effort during use. - 90-degree bend construction: The wrenches feature a 90-degree angle bend, which helps the bend stay in place and minimizes springback for stable operation in tight spaces. - Use scenarios: - Assembling flat-pack furniture or equipment that uses deep-set screws in restricted areas. - Automotive or bicycle maintenance in cramped engine bays or frame points. - General home/workshop tasks requiring durable, corrosion-resistant wrenches with clear color coding.
