Product Description
This C-type box-end wrench is forged from premium chrome-vanadium steel, offering high hardness, good toughness, and long-lasting durability. Its unique curved C-shaped body provides extra clearance around obstacles, making it ideal for fasteners located at special angles, in recessed positions, or in confined spaces.
Both ends feature box-end profiles for two different metric sizes. The precisely machined ring profiles provide even force distribution and stable engagement with hex nuts and bolts, helping reduce slipping and fastener damage. The wrench is finished with mirror chrome plating for a bright professional appearance, excellent rust resistance, and corrosion protection.
This curved box wrench is especially suitable for automotive repair, furniture installation, plumbing, machinery maintenance, and other applications where standard straight wrenches cannot access the fastener effectively.

FAQ
Q1: What is the difference between a C-type box wrench and a standard box wrench?
A1: A C-type box wrench has a curved, arch-shaped body that provides extra clearance around obstacles, pipes, and nearby parts. A standard box wrench usually has a straight handle.
Q2: Where is the C-type design most useful?
A2: It is especially useful in automotive engine bays, chassis areas, air-conditioning lines, plumbing installations, cabinet assembly, and machinery interiors where access is restricted.
Q3: What material is this wrench made from?
A3: It is forged from premium chrome-vanadium steel for high hardness, good toughness, and reliable durability.
Q4: Is the surface rust-resistant?
A4: Yes. The mirror chrome-plated finish provides good rust and corrosion resistance. Wipe the wrench clean after use and store it in a dry environment for best protection.
Q5: What are the benefits of the double box-end design?
A5: It provides two sizes in one wrench. The box-end profile surrounds the nut or bolt more completely, distributes force evenly, and helps reduce slipping.
Q6: Can it be used for seized or high-torque bolts?
A6: It is suitable for standard fastening, installation, and maintenance work. For severely rusted, seized, or extremely high-torque fasteners, use penetrating oil and appropriate high-torque tools such as sockets or breaker bars.
Q7: Do you support customization?
A7: Yes. OEM/ODM customization is available for logos, size combinations, plating finishes, packaging, and tool set configurations.
