Welcome to Cangzhou Dean Safety&Special Tools Co., Ltd — a trusted manufacturer since 2001, exporting over US$100 million annually to global markets including North America, South America, Europe, Africa, and Asia. We present our Polished Combination Wrench in 304 Stainless Steel, engineered for demanding industrial environments.

Whether you need a standard length from 120mm to 470mm or custom specifications, our industrial-grade wrench ensures reliable performance and long service life.
Product Features & Advantages
- Premium Material: 304 stainless steel (0Cr18Ni9) offers excellent resistance to rust, acids, and high temperatures — ideal for marine, chemical, food processing, and outdoor applications.
- Mirror-Like Polish: Our proprietary polishing process creates a smooth, bright surface that not only looks professional but also resists dirt and corrosion buildup, making cleaning effortless.
- Combination Design: One end features a 12-point open end for quick access, while the other end has a 12-point box end for maximum grip and torque. This dual functionality reduces tool changes and improves efficiency.
- Precision Machining: Each wrench is forged and machined to tight tolerances (typical deviation ±0.1mm) to ensure a snug fit on fasteners, minimizing rounding and slipping.
- Long Service Life: Heat-treated and hardened to HRC 38–45, offering superior strength and wear resistance without compromising ductility.
- Ergonomic Handle: Smooth, polished handle provides comfortable grip even in oily or wet conditions; chamfered edges prevent hand fatigue during prolonged use.
- Industrial Grade Quality: Every tool passes visual inspection and dimensional testing to meet consistent quality standards suitable for heavy-duty applications.

Frequently Asked Questions
-
Q: Is 304 stainless steel wrench non-magnetic?
A: 304 stainless steel in the annealed condition is essentially non-magnetic. However, after cold working (like forging), it can become slightly magnetic. This is normal and does not affect corrosion resistance or performance. If you require fully non-magnetic tools, please contact us for alternative materials. -
Q: Can I get inch (SAE) sizes instead of metric?
A: Yes, we can supply both metric and inch sizes. Common inch sizes include 3/8", 1/2", 5/8", 3/4", etc. Please specify your requirements when ordering. -
Q: How does the polished surface hold up in rough environments?
A: The mirror polish provides an extra barrier against corrosion and dirt accumulation. Regular cleaning with mild soap and water will maintain its luster. For heavy-duty use, the polished finish is more durable than brushed or matte surfaces. -
Q: What is the typical hardness of this wrench?
A: Our industrial-grade 304 stainless steel wrenches are heat-treated to a hardness of HRC 38–45, offering a balance of strength and toughness to prevent breakage under high torque. -
Q: Do you offer custom length wrenches outside 120-470mm?
A: Yes, we can customize lengths from 80mm up to 600mm or more, subject to minimum order quantity. Contact our sales team for details. -
Q: Are these wrenches suitable for spark-sensitive environments?
A: 304 stainless steel is non-sparking when striking against other metals, making it safer in flammable atmospheres compared to carbon steel tools. However, for extreme conditions (e.g., oxygen-rich), we recommend beryllium copper or aluminum bronze tools. Please consult us for specific applications. -
Q: What packaging options do you provide?
A: Standard packaging includes individually poly-bagged or clamshell. We also offer bulk packaging in boxes or custom branding with your logo. For export, we use sturdy cartons and pallets to ensure safe transit. -
Q: What is the typical lead time for large orders?
A: For standard sizes, lead time is 15–25 days depending on quantity. Custom orders may take 25–40 days. We can arrange express shipments for urgent needs.
