Dear Valued Buyer,
Welcome to Cangzhou Dean Safety&Special Tools Co., Ltd – a trusted manufacturer with over 20 years of experience in producing high-quality industrial tools. Since 2001, we have been dedicated to developing reliable safety and specialty tools for global markets, exporting over US$100 million annually to more than 50 countries. Our Non-Magnetic Construction Box Wrench 304 Stainless Steel (19mm Jaw, 240mm Overall) is carefully engineered to meet the demanding requirements of sensitive environments where magnetic interference must be eliminated. Made from premium 304 stainless steel, this wrench combines durability, corrosion resistance, and non-magnetic properties, making it an ideal choice for professionals working in oil & gas, electrical maintenance, aerospace, and military applications.
Product Overview & Key Features
This box wrench is designed with a closed-end construction (12-point box) that provides a secure grip on hexagonal fasteners without slipping. The non-magnetic characteristic ensures that it will not attract metal debris or interfere with sensitive electronic equipment. Below are the core features that set this tool apart:
- Non-Magnetic Performance: The 304 stainless steel material is inherently non-magnetic (permeability
- Corrosion & Rust Resistance: 304 stainless steel offers excellent resistance to oxidation and many corrosive media, extending tool life in humid or chemical environments.
- Ergonomic Design: With an overall length of 240mm, the wrench provides sufficient leverage while remaining compact for confined spaces. Weight of only 240g reduces operator fatigue during extended use.
- Precision Machining: Each jaw is CNC-machined to ensure accurate 19mm opening with tight tolerances (ISO 2768-m), guaranteeing a firm fit on standard fasteners.
- Construction Grade: Built for heavy-duty industrial applications, the wrench can withstand high torque without deformation or breakage.
- Risk-Free for Sensitive Areas: Non-sparking and non-magnetic – perfect for hazardous locations (e.g., oil refineries, chemical plants, gas pipelines).

Frequently Asked Questions (FAQ)
-
What does “non-magnetic” mean for a wrench?
Non-magnetic wrenches are made from materials with very low magnetic permeability (e.g., 304 stainless steel). They will not be attracted to magnets and will not interfere with sensitive electronic or magnetic equipment. This is crucial in environments like MRI rooms, aircraft maintenance, or explosive gas areas. -
Is this wrench completely non-sparking as well?
While 304 stainless steel is non-magnetic, it is not classified as non-sparking. For spark-free applications, we recommend our beryllium copper or aluminum-bronze tools. However, the non-magnetic property is a distinct advantage for many industrial settings. -
Can I get this wrench in a different jaw size?
Yes. We manufacture a full range of non-magnetic construction box wrenches from 6mm to 55mm. The 19mm version is our standard stock item. Custom sizes can be produced with minimum order quantities. -
How should I clean and maintain this stainless steel wrench?
Simply wipe with a clean cloth after use. If exposed to salt water or chemicals, rinse with fresh water and dry. For stubborn stains, use mild soap and a soft brush. Avoid abrasive cleaners that may scratch the surface. -
Do you provide samples before bulk purchase?
Yes. Sample orders are welcome. We can ship a single piece for evaluation. Please contact our sales team for sample availability and shipping cost. -
What is the typical lead time for orders?
For stock items (19mm), lead time is around 3-7 days. For custom sizes or special packaging, lead time depends on quantity but typically 15-25 days after confirmation. -
Are these wrenches certified for use in explosive atmospheres?
The wrenches themselves do not carry specific ATEX/IECEx certification, but the non-magnetic property is an inherent characteristic of the material. If you require certified non-sparking tools for Zone 0/1, we can provide alternative options. Please consult our technical team. -
What is the warranty period?
We offer a standard 12-month warranty against manufacturing defects. For serial production, we can negotiate extended warranty based on order volume.
