Cangzhou Dean Safety & Special Tools Co., Ltd., a manufacturer with over two decades of experience since 2001, is proud to present the CR-V Steel Striking Hex Wrench (2-12mm). Crafted from premium chrome-vanadium steel with a hardened black phosphate finish, this wrench is engineered for heavy-duty striking applications where standard wrenches fall short. Our annual export value exceeding US$100 million reflects the trust placed in us by global markets across North America, Europe, Asia, and beyond. This wrench combines durability, precision, and safety, making it an essential tool for mechanics, industrial maintenance crews, and construction professionals.
The striking hex wrench is designed to withstand repeated hammer blows without deformation or cracking. Its 2-12mm hex size range covers most common fastener requirements, while the black phosphate coating provides excellent corrosion resistance and a non-glare surface for improved visibility in low-light workspaces. Each wrench undergoes rigorous hardening to achieve optimal strength and wear resistance.
Key Features & Technical Specifications
Material: Premium CR-V (Chrome Vanadium) steel – known for exceptional toughness and fatigue resistance.
Hardness: Heat-treated to HRC 48-52, ensuring long service life under repeated striking.
Surface Finish: Hardened black phosphate – reduces friction, prevents rust, and offers a matte appearance.
Striking Face: Flat, wide striking surface designed for use with hammers or mallets, minimizing slippage.
Hex Opening: Precision-machined to tight tolerances for a secure fit on fasteners, reducing rounding.
Sizes Available: From 2mm to 12mm (individual or complete sets upon request).
Packaging: Available in blister packs, plastic holders, or custom tool rolls for easy organization.
Why choose our striking hex wrenches over standard wrenches? Ordinary hex wrenches are not designed to absorb impact; they can chip, crack, or lose their shape. Our wrenches feature a reinforced shank and thickened striking head to handle the demands of heavy-duty loosening or tightening tasks where corrosion or rust has seized fasteners. The black phosphate finish also provides a comfortable grip and resists chemical spills common in automotive and industrial environments.
| Size (mm) | Overall Length (Approx.) | Weight (g) |
|---|---|---|
| 2 | 80 mm | 25 |
| 4 | 100 mm | 40 |
| 6 | 120 mm | 60 |
| 8 | 140 mm | 85 |
| 10 | 160 mm | 110 |
| 12 | 180 mm | 140 |
Benefits for your workflow:
- Time-saving: The striking design allows you to apply impact force directly, loosening stubborn fasteners faster than conventional wrenches.
- Safety: The flat striking face reduces the risk of the hammer slipping off, preventing hand injuries.
- Cost-effectiveness: Long tool life means fewer replacements; our hardened CR-V steel resists wear and breakage.
- Versatility: Suitable for use in tight spaces where a ratchet or socket cannot fit; simply strike with a hammer to break torque.

Frequently Asked Questions (FAQ)
Q1: What is the difference between this striking wrench and a regular hex wrench?
A: This striking hex wrench is specifically designed to withstand hammer blows. It has a thicker, reinforced striking head and is made from hardened CR-V steel, whereas a standard hex wrench is not rated for impact and may break or deform under force.
Q2: Can it be used with power tools like an impact driver?
A: This wrench is intended for manual striking with a hammer or mallet. It is not designed for use with power impact drivers; using it with a power tool may cause damage or injury.
Q3: Is the black phosphate finish durable?
A: Yes. The hardened black phosphate coating provides excellent corrosion resistance and wear protection. It also reduces glare and improves grip. However, like all coatings, it may wear over time with heavy use.
Q4: Do you offer the wrenches as a complete set?
A: Yes, we can supply the 2-12mm range as a full set, or we can pack individual sizes according to your preference. Custom sets are also available – please inquire.
Q5: What is the hardness of these wrenches?
A: They are heat-treated to a hardness of HRC 48-52, which provides an optimal balance between toughness and wear resistance without being brittle.
Q6: Can you customize the packaging with my company logo?
A: Yes, we offer custom packaging options, including logo printing and specialized tool rolls. Contact our sales team for details and minimum order quantities.
Q7: What is the lead time for an order?
A: Lead time typically ranges from 15 to 30 days depending on quantity and customization. We ship from Tianjin, Shanghai, or Ningbo ports. Please contact us for an accurate estimate.
Q8: Are these wrenches suitable for use with hex keys (Allen keys)?
A: No, this is a striking hex wrench with a hex opening for hex-head bolts and screws. It is not a hex key (Allen key). It is designed to be struck with a hammer to turn hexagonal fasteners.
