From Cangzhou Dean Safety&Special Tools Co., Ltd — a trusted manufacturer with over 20 years of experience and annual export value exceeding US$100 million — we proudly present our Single Ring Box Wrench with Offset Handle. This wrench is engineered for high torque output and features a generous 80mm opening, making it an indispensable tool for heavy-duty industrial applications. Crafted from drop-forged steel, it delivers exceptional strength and durability, allowing professionals to tackle the toughest fastening tasks with confidence.
Our offset handle design provides optimal leverage and clearance, enabling you to work in confined spaces where traditional straight wrenches cannot reach. The single ring box end ensures a full 360° contact with the fastener, minimizing slippage and rounding of corners. Ideal for maintenance crews, assembly lines, and repair shops, this wrench is built to withstand repeated high-stress use.
Key Features & Technical Specifications
- Forged Steel Construction: One-piece drop forging for maximum grain flow and structural integrity, offering superior toughness compared to cast alternatives.
- 80mm Opening: Accommodates large hexagonal nuts and bolts commonly found in heavy machinery, piping systems, and structural steel.
- Offset Handle: 15° offset angle (typical) improves access to recessed fasteners and allows comfortable hand clearance.
- High Torque Output: Reinforced box end and thicker shank design deliver up to 30% more torque resistance than standard wrenches of similar size (based on internal testing).
- Versatile Application: Suitable for use in oil & gas, mining, construction, shipbuilding, and general industrial maintenance.
- Customizable Options: Available in Chrome Vanadium or Chromium-Molybdenum steel, with various surface finishes (phosphate, black oxide, chrome plating) upon request.

Frequently Asked Questions
Q1: What is the main advantage of an offset handle wrench?
A1: The offset handle allows you to access fasteners located in tight or recessed areas where a straight wrench cannot fit. It also provides better hand clearance and reduces the risk of knuckle injury.
Q2: Can this wrench handle extremely high torque without breaking?
A2: Yes, the forged steel construction and reinforced box end are designed to withstand high torque levels. However, exact torque capacity depends on material and heat treatment. We recommend staying within the tool's rated capacity (details provided with the product).
Q3: Is the 80mm opening suitable for SAE or metric fasteners?
A3: The 80mm opening is a metric size and typically fits 80mm hexagonal fasteners. If you need a different size, we offer custom openings from 50mm to 100mm upon request.
Q4: Does the wrench come with any surface protection against rust?
A4: Our standard finish is black oxide or phosphated, which provides moderate corrosion resistance. For higher protection, we can apply chrome plating or zinc-nickel coating as an option.
Q5: Can I get a sample before placing a large order?
A5: Certainly. We provide sample orders with a reasonable lead time and cost. Once the sample is approved, we can proceed with mass production.
Q6: What is the minimum order quantity (MOQ)?
A6: For standard sizes, MOQ is typically 100 pieces. For custom specifications, MOQ may be higher. Please contact our sales team for details.
Q7: Do you offer customization of the handle length or offset angle?
A7: Yes, we can customize handle length (e.g., 400mm, 600mm) and offset angle within a practical range. Additional tooling costs may apply.
Q8: Are these wrenches certified to any international standards?
A8: Our wrenches are manufactured in accordance with DIN 899 and ASME B107.100. We can provide a certificate of compliance upon request. Specific certifications (e.g., CE, ISO) are available if required — please discuss with our sales representative.
