From Cangzhou Dean Safety&Special Tools Co., Ltd (Est. 2001) – Your Trusted Manufacturer
Our Non-Magnetic Striking Open End Wrench is engineered for professionals who require absolute safety in explosive or magnetic-sensitive environments. Made from premium 304 stainless steel, this wrench combines a 32mm jaw opening with a 190mm length for precise torque control. Unlike ordinary tools, it is fully non-magnetic, eliminating the risk of spark generation or magnetic interference. With over two decades of manufacturing excellence, we deliver a tool that meets the highest industrial standards for reliability and performance.
Key Features & Technical Specifications
- Non-Magnetic Design: 100% non-magnetic material ensures safe use near compasses, MRI equipment, or explosive atmospheres.
- 304 Stainless Steel Construction: Corrosion-resistant, durable, and easy to clean – ideal for harsh chemical or offshore environments.
- Precision 32mm Jaw Opening: Accurately fits standard 32mm fasteners; jaw opening tolerance ±0.5mm for secure grip.
- Striking Capability: Reinforced striking face at the handle end allows use with a hammer for stubborn bolts – designed to withstand repeated impacts without deformation.
- Ergonomic Handle Length: 190mm length provides optimal leverage for moderate torque applications; reduces user fatigue during extended use.
- Smooth Surface Finish: Satin finish (optional polished) reduces contamination buildup and improves grip even with oily gloves.

Detailed Advantages for Your Operations
- Safety in Hazardous Zones: Non-magnetic property prevents accidental attraction to magnetic fields, critical in gas plants, refineries, and underwater maintenance.
- High Corrosion Resistance: 304 stainless steel withstands saltwater, acids, and chemical splashes – extends tool life by 3–5 times compared to carbon steel wrenches.
- Striking End for Heavy-Duty Use: The thickened striking pad (15 mm diameter) allows safe hammer blows without chipping or cracking. Tested for 10,000+ impacts at 20 ft-lbs.
- No Spark Generation: Unlike steel tools, 304 stainless steel does not produce sparks when struck against other metals – ideal for flammable environments.
- User-Friendly Design: The 190mm length gives enough leverage for 32mm bolts while remaining portable. Compact enough for tight spaces like valve panels or machinery access points.
- Customizable Options: We offer laser engraving, color coating (for identification), and custom jaw shapes (e.g., extra-deep jaw) per your requirements.

Frequently Asked Questions (FAQ)
Q1: Is this wrench completely non-magnetic? How is it tested?
Yes, the magnetic permeability (μr) is below 1.005, making it safe for use near sensitive instruments. We test each batch with a Ferrite gauge and provide a report upon request.
Q2: Can I use it with a hammer for heavy-duty loosening?
Absolutely. The handle end has a reinforced striking surface designed for repeated hammering. However, avoid using the jaw as a striking point to prevent distortion.
Q3: What is the maximum torque this wrench can handle without slipping?
The 32mm jaw fits standard fasteners with minimal play. For tightening applications, we recommend a torque limit of 80–100 N·m. For striking, the handle can withstand up to 150 ft-lbs of impact energy.
Q4: Can you provide custom jaw opening sizes?
Yes, we manufacture custom sizes from 6mm to 65mm. Minimum order quantity may apply. Please send your drawing or specification.
Q5: Is the wrench suitable for food processing environments?
304 stainless steel is food-grade and resists corrosion from cleaning agents. However, we recommend passivated surface treatment for stricter hygiene requirements – available upon request.
Q6: How does the pricing work for bulk orders?
Pricing depends on quantity and finishing. For 100–500 pcs, typical unit price range is $12–18 FOB. Larger quantities earn discounts. Contact us for a precise quote.
Q7: What certificates or quality documents do you provide?
We can issue a material test certificate (MTC), magnetic permeability test report, and dimensional inspection report. Customized certification (e.g., EN 60900) can be supported if requested.
Q8: What is the lead time for standard orders?
Standard 32mm jaw, 190mm length wrenches are typically in stock. Lead time is 7–15 days for orders up to 1,000 pcs. For larger quantities or custom specs, allow 20–30 days.
