| Parameter | Detail |
|---|---|
| Material | 304 Stainless Steel (non-magnetic) |
| Opening Range | 17 mm to 32 mm (0.67 to 1.26 inches) |
| Surface Treatment | Polished or satin finish (optional) |
| Magnetic Permeability | μ ≤ 1.01 (tested per ASTM A342) |

Our design incorporates a compact box end with 12-point configuration for superior grip and reduced fastener rounding. The wrench is ideal for applications where standard steel tools could cause magnetic field distortion or attract metal debris. Key benefits include:
- Non-Magnetic Performance: 304 stainless steel ensures minimal magnetic interference, critical for sensitive electronic components or MRI environments.
- Corrosion Resistance: Resists rust and chemical attack, extending tool life in humid, marine, or chemical processing settings.
- Ergonomic Handle: Contoured grip reduces hand fatigue during prolonged use; the box end allows for higher torque application.
- Versatility: One tool covers 15 common fastener sizes from 17 to 32 mm, replacing multiple single-size wrenches.
- Durable Construction: Heat-treated 304 stainless steel provides hardness comparable to carbon steel tools while maintaining non-magnetic properties.
- Custom Options Available: We offer custom openings, laser marking, and packaging per buyer requirements.
The wrench's dimensional tolerances conform to ANSI/ASME B107.100 and DIN 3113 standards (upon request), ensuring interchangeability with international fasteners. Each tool is individually tested for opening accuracy and magnetic permeability before shipment. For bulk orders, we can provide inspection reports upon request.

Frequently Asked Questions
-
Q: Is this wrench completely non-magnetic? Can it be used near MRI machines?
A: Yes, the 304 stainless steel used has a magnetic permeability under 1.01 (tested), making it suitable for most non-magnetic environments including MRI rooms and electronic assembly. However, it is not certified as fully amagnetic (permeability -
Q: What is the torque capacity of this wrench?
A: The wrench is designed for manual use and can handle torque up to approximately 150 N·m depending on the size. For heavy-duty industrial use, we recommend our forged alloy steel series. The box end design reduces slip and allows for better torque application compared to open-end wrenches. -
Q: Does the wrench come with a calibration certificate?
A: Standard shipments do not include a calibration certificate, but it can be provided at additional cost. Dimension and material test reports are available upon request for bulk orders. -
Q: What is the hardness of the 304 stainless steel used?
A: After heat treatment, the surface hardness typically ranges from HRB 80-90, offering good wear resistance while maintaining non-magnetic properties. This is softer than hardened carbon steel but adequate for regular fastener tightening and loosening. -
Q: Can I get the wrench with a different opening range, e.g., 10-18mm?
A: Yes, we can customize the opening size according to your requirements. Minimum order quantity may apply. Contact our sales team with your desired specification for a quote. -
Q: How is the tool shipped? Can it be packed in a tool roll or pouch?
A: We ship via sea freight or air freight from Tianjin/Shanghai/Ningbo. Standard packaging is individual blister card or polybag. Custom packaging like canvas rolls, plastic cases, or laser-engraved logos is available with MOQ. -
Q: Does the 1-year warranty cover breakage from over-torquing?
A: The warranty covers manufacturing defects such as material flaws or improper heat treatment. Damage from over-torquing, misuse, or modification is not covered. We recommend using the tool within its intended torque range to maximize lifespan. -
Q: What is the lead time for an order of 500 pieces?
A: For a standard order of 500 pieces, lead time is typically 25-35 days after confirmation of sample and payment. For custom specifications, add 10-15 days for tooling and sampling.
