Cangzhou Dean Safety&Special Tools Co., Ltd. proudly presents our Non-Magnetic Construction Hexagonal Box Wrench – a precision tool designed for professionals who work in environments where magnetic interference is critical. Crafted from high-quality 304 stainless steel, this wrench eliminates the risk of attracting ferrous particles or affecting sensitive equipment, making it an essential choice for aerospace maintenance, oil and gas operations, and electronics assembly. With a 17 mm opening and an extended 310 mm length, it offers both the perfect fit for standard fasteners and the leverage needed for efficient torque application.
As a trusted manufacturer since 2001, we have supplied over 100 million USD worth of specialty tools annually to global markets including North America, Europe, Asia, and Oceania. Our hexagonal box wrenches undergo rigorous quality control to ensure each unit meets the highest standards of durability, corrosion resistance, and non-magnetic performance. Below, we detail the technical specifications and benefits that set this tool apart.
Product Features & Benefits
- Non-Magnetic Material: Made from 304 stainless steel with low magnetic permeability, ideal for use in MRI rooms, clean rooms, and explosive environments where sparks or magnetic attraction must be avoided.
- Optimal Opening Size: 17 mm hex box end fits hex nuts and bolts securely, reducing slippage and rounding damage.
- Extended Length: 310 mm (12.2 inches) provides extra leverage for loosening or tightening fasteners without excessive force, reducing user fatigue.
- Corrosion Resistance: 304 stainless steel resists rust and chemicals, suitable for harsh industrial and marine applications.
- One-Piece Construction: Forged from solid bar stock, no welded joints – ensures maximum strength and longevity.
- Passivated Surface: Smooth finish prevents contamination and facilitates easy cleaning, compatible with sterilization procedures.
- Ergonomic Handle: Comfortable grip design reduces hand stress during prolonged use.

Detailed Product Description
The Non-Magnetic Construction Hexagonal Box Wrench is engineered for professionals who require absolute reliability in non-magnetic applications. The 304 stainless steel alloy used in its manufacture has a magnetic permeability of less than 1.03 µ (microhenry per meter), effectively preventing attraction to magnetic fields and reducing the risk of spark generation. This makes the wrench indispensable for work near sensitive electronics, MRI scanners, oil refineries, and gas plants.
The 17 mm hex opening is precision-machined to provide a snug fit on standard hex fasteners, minimizing cam-out and damage to bolt heads. The 6-point box design fully encloses the nut, allowing for higher torque application without slipping. The wrench’s 310 mm length offers a mechanical advantage that reduces the effort needed to break loose tight fasteners or to torque larger bolts. Despite its length, the tool remains well-balanced, with a center of gravity positioned near the handle for comfortable control.
Durability is further enhanced by the one-piece forging process – there are no welded joints that could weaken under stress. The passivated surface not only provides an attractive satin finish but also removes free iron ions, improving corrosion resistance and making the tool suitable for cleanroom and food processing environments. Each wrench is individually inspected for dimensional accuracy, surface hardness (Rockwell B80-90), and non-magnetic properties.
Applications: This wrench is ideal for:
- Aerospace assembly and maintenance
- Oil and gas industry (offshore and onshore)
- Chemical and pharmaceutical plants
- Electronics and semiconductor manufacturing
- Medical equipment servicing (MRI, X-ray)
- Automotive performance and restoration
- Marine and offshore operations

Frequently Asked Questions (FAQ)
-
Q: Is the wrench truly non-magnetic?
A: Yes, the 304 stainless steel used has a magnetic permeability below 1.03 µ, making it effectively non-magnetic for most sensitive applications. We can provide a test report upon request. -
Q: Can I use this wrench for tightening or only loosening?
A: It is designed for both tightening and loosening hex nuts/bolts. The box end provides full 360-degree engagement, allowing you to apply torque in either direction. -
Q: What does “17 mm opening” mean exactly?
A: It means the hex opening measures 17 millimeters across opposite flats, suitable for a 17 mm hex nut or bolt head. -
Q: Is the surface treatment food-grade or cleanroom compatible?
A: The passivated surface is free of contaminants and can be sterilized. It is suitable for food processing, pharmaceutical, and cleanroom environments. -
Q: Can I get the wrench in other lengths or opening sizes?
A: Yes, we offer customization. Please contact our sales team to discuss your specific needs. -
Q: What is the warranty on this tool?
A: We provide a one-year warranty against manufacturing defects. Extended warranty options are available for bulk orders. -
Q: How do I clean and maintain the wrench?
A: Wipe with a damp cloth after use. Avoid abrasive cleaners. Stainless steel can be periodically passivated if exposed to harsh chemicals. -
Q: Is this wrench compatible with torque wrenches or extensions?
A: This is a standalone hand wrench. For use with torque wrenches, we recommend our non-magnetic socket adapters (available separately).
