Cangzhou Dean Safety&Special Tools Co., Ltd, established in 2001 and headquartered in Cangzhou, Hebei, China, is a specialized manufacturer dedicated to producing high-quality safety and special tools. With an annual export value exceeding US$100 million and a proven track record of supplying to over 15 major global markets including North America, Europe, and Southeast Asia, we bring unmatched expertise to every product we craft. The Hexagonal Box Wrench Non-Magnetic, 304 Stainless Steel, Corrosion Resistant, 17 mm Opening, 310 mm Length exemplifies our commitment to precision and performance. Engineered for professionals who demand reliability in environments where both magnetic interference and corrosion are critical concerns, this wrench is a valuable addition to any serious tool kit.
Our wrench is forged from high-grade 304 stainless steel, a material known for its excellent corrosion resistance and non-magnetic properties. Unlike standard carbon steel wrenches that can become magnetized and attract metallic debris, or rust when exposed to moisture, this 304 stainless steel version remains clean and durable even in harsh conditions. The 17 mm hexagonal opening is precision-machined to meet international tolerance standards, ensuring a snug fit on fasteners without rounding edges. The 310 mm total length provides optimal leverage for loosening or tightening bolts while reducing hand fatigue.
Designed for heavy-duty industrial use, this wrench is ideal for applications in marine repairs, oil & gas installations, chemical processing plants, and pharmaceutical facilities where non-magnetic tools are required to avoid interfering with sensitive electronic equipment or where corrosion from chemicals or saltwater is a constant threat. The hexagonal box end delivers 360-degree contact with the fastener, minimizing slippage and improving torque transfer.

Key Benefits for Your Operations:
- Non-Magnetic Safety: Essential for work near MRI machines, aviation avionics, or magnetic-sensitive instruments – eliminates risk of tool magnetization attracting metal shavings or interfering with delicate electronics.
- Superior Corrosion Resistance: 304 stainless steel withstands rust, stains, and chemical attack. Ideal for wet, salty, or acidic environments like shipyards, offshore platforms, and chemical refineries.
- Precision Hexagonal Fit: The 12-point (or 6-point) internal hex design grips fastener flats firmly, reducing rounding and extending tool life. Each opening is laser-checked for dimensional consistency.
- Ergonomic Length: At 310 mm, it provides balanced leverage for breaking loose stubborn bolts without being unwieldy – reduces strain on your hands and wrists during repeated use.
- High-Strength Construction: Heat-treated and forged from solid bar stock, not cast. This eliminates internal defects and ensures the wrench withstands high torque without deformation.
- Low Maintenance: No plating or coating to wear off; the natural passivation layer of stainless steel is self-healing. Simple rinsing with water after use restores its appearance.
Every wrench is individually inspected before leaving our factory. We employ rigorous quality control procedures including dimensional checks using calibrated gauges, hardness testing, and magnetic permeability verification to confirm non-magnetic properties. This commitment to excellence is why customers across North America, South America, Eastern Europe, Africa, Oceania, and the Middle East trust Dean Tools for their critical applications.
We also offer customization options: engraving of logos, special packaging (foam inserts or blister packs), and batch testing reports upon request. Whether you need a single piece for a maintenance kit or thousands for an industrial project, our streamlined production capacity of over 100,000 units per month ensures fast delivery. With shipping ports in Tianjin, Shanghai, and Ningbo, we can efficiently serve any destination worldwide.

FAQ – Hexagonal Box Wrench Non-Magnetic, 304 Stainless Steel
-
Q: What does “non-magnetic” actually mean for this wrench?
A: The 304 stainless steel used has a magnetic permeability of less than 1.005, meaning it will not attract magnets significantly. This ensures safe use in environments where magnetic field interference is a concern, such as near MRI machines, electronic assembly lines, or aviation maintenance. -
Q: Is this wrench suitable for use in food processing or pharmaceutical industries?
A: Yes. 304 stainless steel is FDA-approved for food contact and resists corrosion from cleaning agents. The non-magnetic property also prevents metal contamination in sensitive products. -
Q: Can I use this wrench on over-torqued bolts?
A: The 310 mm length provides good leverage, but like any hand tool, use appropriate caution. The wrench is designed for standard hand operation; if extreme torque is needed, ensure a correct fit and avoid using pipe extensions that may damage the tool. -
Q: Does the wrench come with a certificate of non-magnetic properties?
A: Yes, we can provide a batch test report for magnetic permeability upon request. Please mention this requirement when placing an order. -
Q: What is the tolerance of the 17 mm opening?
A: The opening is machined to within ±0.1 mm of the nominal size, ensuring a precise fit on standard metric fasteners. We follow ISO 6788 tolerances for box wrenches. -
Q: Is the wrench available in other sizes or lengths?
A: Yes, we offer a full range of hex box wrenches from 6 mm to 36 mm openings and varying lengths. Contact our sales team for a complete size chart and availability of special dimensions. -
Q: How should I clean and maintain this stainless steel wrench?
A: After use, simply wipe clean with a cloth or wash with mild soap and water. Avoid abrasive cleaners that could scratch the surface. For heavy grease or chemical residues, use a solvent compatible with stainless steel. -
Q: What packaging options do you offer for wholesale orders?
A: Standard bulk packaging is in cardboard boxes. Custom packaging such as foam cutouts, blow-molded cases, or branded polybags can be arranged based on quantity. Please discuss your requirements with our sales representative.
