Cangzhou Dean Safety&Special Tools Co.,Ltd, a trusted manufacturer since 2001, proudly presents the Non-Sparking Striking Box Wrench 17mm in Aluminum Bronze. With an annual export value exceeding US$100 million and shipments flowing through Tianjin, Shanghai, and Ningbo ports, we deliver high-quality safety tools to markets worldwide including North America, South America, Europe, and Asia. This striking box wrench is engineered for use in hazardous environments where sparks can ignite flammable gases or dust. The aluminum bronze construction ensures zero spark generation, making it an essential tool for professionals in oil refineries, chemical plants, mines, and marine operations.
Product Overview:
The 17mm Non-Sparking Striking Box Wrench is specially designed for heavy-duty applications requiring impact force. The box end provides a secure grip on hexagonal fasteners, while the striking face allows hammer blows to loosen or tighten stubborn bolts. Unlike standard steel wrenches, the aluminum bronze alloy prevents the formation of sparks even when struck against steel or concrete surfaces, eliminating ignition risks. This tool combines safety with durability – the material’s natural corrosion resistance ensures long service life in harsh environments.

Key Features & Benefits:
- Non-Sparking: The aluminum bronze alloy is certified to be spark-proof, complying with ATEX and NFPA 77 guidelines for explosive atmospheres. No risk of ignition during striking.
- Corrosion Resistance: The material resists rust and chemical attack, making it suitable for offshore and chemical processing applications.
- High Strength: With tensile strength of 690 MPa and yield strength of 300 MPa, the wrench withstands repeated impact without deformation.
- Precision Fit: The box opening is machined to tight tolerances (±0.05mm) to minimize fastener rounding and improve torque transfer.
- Ergonomic Design: The handle length provides leverage while the striking face is flat and angled for effective hammer alignment.
- Lightweight: Approximately 30% lighter than equivalent steel wrenches, reducing operator fatigue.
- Customizable: Available in metric and imperial sizes; custom lengths and markings can be provided upon request.
Applications:
This striking box wrench is ideal for use in Zone 1/2 hazardous areas, including:
- Oil and gas refineries (storage tanks, pipelines)
- Chemical processing plants (reactors, distillation columns)
- Coal mines and underground mining operations
- Shipbuilding and marine engineering
- Aerospace maintenance (fuel systems)
- Pharmaceutical and paint manufacturing (flammable solvents)

Frequently Asked Questions (FAQ)
-
Q: Is this wrench truly non-sparking even when struck against steel?
A: Yes. Our aluminum bronze alloy contains no ferrous metals that can produce sparks. Even under heavy impact, the tool will not create a spark, meeting the requirements for use in explosive environments. -
Q: Can I use this wrench for torquing applications?
A: While primarily designed for striking (impact), the box end can also be used with a standard handle for manual torque. However, for accurate tightening, we recommend a torque wrench. -
Q: What sizes are available besides 17mm?
A: We offer a full range from 6mm to 80mm (including imperial sizes 1/4" to 3"). Custom sizes are available upon request with minimum order quantities. -
Q: How does aluminum bronze compare to beryllium copper?
A: Both are non-sparking. Aluminum bronze is lighter and more cost-effective, while beryllium copper is harder but more expensive. Our aluminum bronze is suitable for most industrial applications. -
Q: Do you provide certification or test reports?
A: Yes. Material test certificates and spark-proof verification reports are available upon request. We also provide ISO 17025 calibration services for critical measurements. -
Q: What is the delivery time?
A: Standard sizes (17mm) are in stock and can ship within 5-7 business days. Custom orders typically require 15-20 working days depending on volume and specifications. -
Q: How should I maintain this wrench?
A: Clean after use with a dry cloth; avoid exposure to strong acids. Apply a light oil coating if stored in humid environments. Do not use steel brushes that may scratch the surface. -
Q: Can I get a sample before bulk order?
A: Absolutely. We offer sample orders with shipping costs covered by the buyer. Sample cost is refundable upon bulk order placement (minimum 50 pcs).
