Professional-Grade Industrial Bent Single Open End Wrench – 27mm, 240mm Length, 45# Steel
As a manufacturer with over two decades of experience in the safety and special tools industry, Cangzhou Dean Safety & Special Tools Co., Ltd is proud to present our Industrial Bent Single Open End Wrench (also known as a Single-End Box Spanner) crafted from high-quality 45# steel. This tool is engineered for demanding industrial environments where precision, durability, and leverage are critical. With a precise 27mm opening and an overall length of 240mm, the bent design provides superior access to recessed fasteners, making it an essential addition to any professional toolkit. Our commitment to strict quality control and competitive pricing ensures that you receive a reliable, long-lasting wrench that delivers consistent performance.
Key Features & Technical Specifications
- Material Excellence: Made from premium 45# medium carbon steel, heat-treated to achieve optimal hardness and toughness. This material offers an excellent balance of strength and ductility, resisting deformation under heavy torque.
- Bent Offset Design: The head is angled at approximately 15° to 20° (standard) to allow easy operation on nuts or bolts located in tight, recessed, or awkward positions. This ergonomic geometry reduces user fatigue and improves safety.
- Precise Dimensions: The wrench is precision-machined to fit a 27mm hex fastener accurately, minimizing slippage and rounding damage. Overall length of 240mm provides adequate leverage for loosening and tightening tasks without being overly bulky.
- Single-End Box Spanner Configuration: This tool features a single open end with a box (closed) profile on the opposite end? Actually, the product name indicates a single open end with a bent shank; the term "Single-End Box Spanner" is used in some regions to describe a single head wrench. In our design, the open end is robust and precisely broached for secure grip.
- Surface Finish: Available in plain black oxide or as per customer request (e.g., phosphate, chrome-plated). The standard finish offers corrosion resistance and a non-glare surface suitable for workshop use.
- Customizable Options: Hardness levels (typically HRC 38-42) and length variations can be tailored upon request. We also offer logo printing and individual pouch packaging for branding needs.

Advantages & Customer Benefits
- Enhanced Access: The bent offset allows you to reach nuts on flanges, machinery frames, or behind obstacles where a straight wrench would not fit. This reduces disassembly time and labor costs.
- Durable Construction: Made from 45# steel with proper heat treatment, the wrench resists wear, corrosion, and sudden breakage even under repeated heavy use. It outlasts ordinary carbon steel tools.
- Accurate Fit: Each wrench is machined to tight tolerances (typically ±0.2mm on opening) to prevent fastener damage and ensure secure engagement. This reduces the risk of rounding off bolt heads.
- Ergonomic Handle: The 240mm length provides sufficient torque without excessive weight. The smooth shank reduces hand fatigue during prolonged use.
- Cost-Effective: As a direct manufacturer, we offer factory prices without sacrificing quality. Bulk orders enjoy further discounts and flexible shipping options.
- Wide Compatibility: The 27mm size is common in industrial equipment, heavy machinery, trucks, and agricultural vehicles. It is a versatile addition to any mechanic's set.

Frequently Asked Questions (FAQ)
-
Q: Is this wrench single-ended or double-ended?
A: This is a single-ended wrench with one open end. The term "Single-End Box Spanner" is sometimes used interchangeably; our design features a bent open end. If you require a double-ended version, we offer that as well upon request. -
Q: What is the maximum torque this wrench can handle?
A: While torque capacity depends on fastener condition and user force, the 45# steel construction and heat treatment provide a working torque of approximately 150-200 Nm under normal conditions. For higher torque applications, consider using a longer handle or a impact wrench. -
Q: Do you offer custom lengths or sizes?
A: Yes, we can customize the length and opening size according to your blueprints or samples. Minimum order quantities apply for non-standard sizes. Please contact our sales team for details. -
Q: What surface treatments are available?
A: Standard finish is black oxide. We also offer phosphate coating, zinc plating, chrome plating, or plain (uncoated). Each finish has its own corrosion resistance and friction properties. Choose according to your environment. -
Q: Can I get a sample before bulk order?
A: Certainly. We provide samples for quality evaluation. Sample cost can be refunded or deducted from a future bulk order. Shipping is at the buyer's expense for samples. -
Q: What is the packaging for export?
A: Usually each wrench is wrapped in a polybag, then packed in strong export cartons or wooden cases as per quantity. Custom blister cards, PVC hangers, or boxes are available for retail presentation. -
Q: Is the wrench magnetic?
A: 45# steel is not inherently magnetic after heat treatment; however, it may exhibit slight magnetism. We can supply demagnetized wrenches if required for electronic or sensitive applications. -
Q: What is the lead time for bulk orders?
A: For standard sizes and finishes, lead time is typically 15-25 days after deposit. For customized orders, it may extend to 30-40 days depending on complexity. Rush orders can be arranged with prior coordination.
