Our Anti-magnetic Double Open-Ended Wrench (18–24mm) is precision-engineered for professionals who demand reliability in sensitive environments. As a trusted manufacturer since 2001, Cangzhou Dean Safety & Special Tools Co., Ltd has delivered over US$100 million in annual exports to global markets. This wrench combines drop forged construction with a passivated coating, ensuring outstanding durability and corrosion resistance while remaining completely non-magnetic — ideal for use near MRI scanners, power transformers, or explosive atmospheres where sparks must be avoided.
Key Features & Benefits
- Anti-magnetic performance – Made from specially selected alloy steel that does not attract or retain magnetism, protecting sensitive equipment and preventing interference.
- Drop forged construction – The wrench is hot forged under high pressure, resulting in a dense grain structure that provides superior strength and fatigue resistance compared to ordinary cast tools.
- Passivated coating – A chemical finish that forms a protective oxide layer, enhancing corrosion resistance in humid, salty, or chemical-laden environments.
- Double open-end design – Both ends feature different jaw sizes (18mm and 24mm), allowing faster fastening without repositioning the tool.
- Ergonomic handle – Smooth, rounded edges reduce hand fatigue during prolonged use; the slim profile reaches into tight spaces.
- Precise jaw alignment – Laser-cut openings ensure a snug fit on hex nuts, minimizing rounding and slippage.

Frequently Asked Questions (FAQ)
-
Q: What does “anti-magnetic” mean for a wrench?
A: It means the tool is made from non-magnetic materials (typically beryllium copper or special stainless steel) and will not attract or become magnetized, preventing interference with sensitive electronic equipment and reducing spark risk in flammable environments. -
Q: Is this wrench also non-sparking?
A: While the passivated coating provides some corrosion resistance, the anti-magnetic property does not guarantee non-sparking behavior. If you require a non-sparking tool (e.g., for explosive atmospheres), please inquire about our beryllium copper or aluminum bronze options which are both anti-magnetic and non-sparking. -
Q: Can I use this wrench for heavy-duty tightening?
A: Yes, the drop forged construction gives high tensile strength, suitable for general mechanical work. However, it is not recommended for impact use or exceeding rated torque values. -
Q: What sizes are available besides 18-24mm?
A: We offer a full range from 6mm to 50mm (single and double open-end). Custom size combinations can be produced with minimum order quantities. -
Q: How does the passivated coating compare to chrome plating?
A: Passivation forms a thin oxide layer that is highly corrosion resistant and environmentally friendly. Chrome plating can be harder but may chip. Passivation is often preferred in clean rooms or chemical labs because no heavy metals are released. -
Q: What is the lead time for bulk orders?
A: For standard sizes like 18-24mm, lead time is 15–20 days after order confirmation. Custom sizes or special coatings may require 25–30 days. -
Q: Do you provide samples before bulk purchase?
A: Yes, sample orders are welcome. We can ship via DHL, FedEx, or Sea. Sample cost is negotiable and can be deducted from the first bulk order. -
Q: How can I ensure the anti-magnetic property is maintained after prolonged use?
A: The anti-magnetic property is inherent to the material; it will not degrade over time. However, do not expose the tool to strong magnetic fields that could induce residual magnetism. Occasional demagnetization using a degaussing coil is possible if needed.
