Cangzhou Dean Safety & Special Tools Co., Ltd — a trusted manufacturer with over 20 years of experience (established in 2001) — presents our premium Double-Ended C-Wrench 10 inch 45# Carbon Steel Heat Treated Hex End. Designed for professionals who demand durability and precision, this wrench combines a traditional C-hook on one end with a convenient hex socket on the other, making it an ideal tool for tightening or loosening round nuts, pipe fittings, and hex bolts in tight spaces. With annual exports exceeding US$100 million, our products are trusted across North America, Europe, Southeast Asia, and beyond. This double-ended wrench is engineered from high-quality 45# carbon steel, undergoes rigorous heat treatment, and is built to withstand daily heavy use in workshops, factories, and repair stations.
- Dual-End Design: One side features a classic C-shaped hook for gripping round or slotted nuts (commonly found on grinders, pumps, and fixtures). The opposite side is a hex socket end perfect for standard hex fasteners. This eliminates the need to switch tools, saving time and effort.
- 45# Carbon Steel Construction: Made from high-strength 45# carbon steel, offering excellent toughness and wear resistance. The material is carefully selected to balance hardness and elasticity, reducing the risk of cracking under high torque.
- Heat Treatment Process: Each wrench undergoes a controlled heat treatment and quenching process to achieve a consistent hardness of HRC 40-45. This ensures superior edge retention and long service life, even when used repeatedly on stubborn nuts.
- Precision Engineering: The C-hook opening and hex socket are machined to tight tolerances, ensuring a snug fit on fasteners to prevent slippage and damage. The 10-inch length (254 mm) provides excellent leverage without being overly bulky.
- Ergonomic & Durable Finish: The surface is treated with a black oxide coating to resist corrosion and reduce glare. The handle is designed for a comfortable grip, and the tool is balanced to minimize wrist fatigue during prolonged use.
- Versatile Applications: Ideal for automotive maintenance, plumbing, HVAC, industrial machinery repair, and general construction. Works well on hex nuts, round slotted nuts, and pipe fittings where a C-wrench is required.

Why Choose Our Double-Ended C-Wrench? The dual function saves you from carrying multiple tools — simply flip the wrench to switch between a C-hook and a hex socket. The heat-treated 45# carbon steel ensures the tool maintains its shape even under repeated high-torque applications, unlike cast iron or low-grade steel alternatives. The precise fit reduces the risk of rounding off fastener corners, protecting both the tool and your workpiece. Plus, the black oxide coating provides rust resistance, making it suitable for humid environments.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between this C-wrench and a standard adjustable wrench?
A: Unlike an adjustable wrench, this tool has a fixed C-hook on one end and a hex socket on the other, specifically designed for round nuts or slotted fasteners (like in angle grinders) and standard hex nuts. It provides a more secure grip without any risk of slipping. -
Q: Can the hex end be used on metric and imperial bolts?
A: The standard hex socket is 13 mm (equivalent to 1/2 inch). Custom sizes are available — please contact our sales team for your specific requirements. -
Q: Is the C-wrench suitable for heavy industrial use?
A: Yes, the 45# carbon steel with heat treatment ensures high strength and durability. It is tested to withstand repeated high-torque applications without deformation. -
Q: Does the black oxide coating provide sufficient corrosion resistance?
A: The black oxide finish offers moderate corrosion resistance for typical workshop environments. For outdoor or marine use, we recommend applying a light oil periodically or requesting a plated finish. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes, we can ship within 15-20 days after order confirmation. Custom orders may require 25-30 days. Our port of shipment is Tianjin, Shanghai, or Ningbo. -
Q: Do you provide OEM/private labeling?
A: Absolutely. We can customize the tool with your brand name, logo, and specific packaging. Minimum order quantities may apply. -
Q: How does the heat treatment improve the wrench’s performance?
A: Heat treatment hardens the steel to HRC 40-45, making the wrench much more resistant to bending, breaking, and wear compared to untreated steel. It also improves edge durability on the C-hook. -
Q: Is this tool suitable for left-handed users?
A: Yes, the wrench is symmetrical and can be used comfortably with either hand. The C-hook works in both clockwise and counterclockwise directions.
