Cangzhou Dean Safety & Special Tools Co., Ltd, established in 2001, takes pride in manufacturing high-quality safety tools for global industries. Our Professional Anti-magnetic Double Open-Ended Wrench, with a 15-degree offset and surface residual magnetism below 0.5mT, is designed for use in sensitive environments where magnetic interference must be strictly avoided. With an annual export value exceeding US$100 million and serving markets across North America, South America, Europe, Asia, Africa, and Oceania, we bring decades of expertise to every tool we produce.
This wrench combines dual open-end functionality with precise anti-magnetic properties, ensuring reliable performance in oil fields, chemical plants, aerospace assembly, defense facilities, and laboratories. Its 15-degree offset provides better access to fasteners in tight spaces, while the rigorous control of residual magnetism (
Key Features & Technical Specifications
Non-magnetic design: Surface residual magnetism
Dual open ends: Two different size openings at each end (e.g., 10×11mm, 12×13mm, up to 27×28mm), saving time and reducing tool changes.
15° offset angle: Provides comfortable wrist posture and enhances torque application, especially in constrained work areas.
Material options: Available in high-strength beryllium copper, aluminum bronze, or other non-magnetic alloys upon request. These materials also offer optional spark-resistant properties for explosive atmospheres.
Precision manufacturing: Each wrench is heat-treated and surface-treated to ensure long service life and dimensional accuracy per ISO standards (available upon request).
Full size range: Covers 10mm to 28mm, meeting common fastener sizes in industrial applications.

Frequently Asked Questions (FAQ)
1. What does 'surface residual magnetism
It means the wrench will not attract ferrous metal particles or interfere with sensitive electronics. 0.5mT (millitesla) is an extremely low level, suitable for use in MRI rooms, laboratories, and semiconductor manufacturing.
2. Are these wrenches spark-proof as well?
Depending on the material selected, they can be. Beryllium copper and aluminum bronze are non-sparking when struck. If you require spark-resistant properties, please specify when ordering.
3. Can I get custom size combinations, like 10×12mm?
Yes, we can manufacture custom opening sizes and combinations for volume orders. Minimum quantities may apply. Please consult our sales team.
4. How is the anti-magnetic property verified?
We use a calibrated Gauss meter to measure residual magnetism on the surface. Test reports can be provided upon request for each batch.
5. What is the delivery time for standard sizes?
For stock items (common sizes), we typically ship within 7-15 days after order confirmation. Custom orders may take 20-30 days depending on volume.
6. Do you provide OEM/private labeling?
Yes, we offer OEM services including custom packaging, laser engraving of logos or part numbers, and specific labeling requirements.
7. Is there a minimum order quantity?
For standard sizes, the MOQ is typically 100 pieces per size. For custom orders, MOQ may be higher. We can discuss flexible terms for trial orders.
8. Which industries commonly use these anti-magnetic wrenches?
They are widely used in oil & gas (near magnetic flow meters), chemical plants, aerospace assembly, defense maintenance, nuclear facilities, and clean rooms.
