Welcome to Cangzhou Dean Safety & Special Tools Co., Ltd. – a trusted manufacturer since 2001 with annual export exceeding US$100 million, serving global markets across North America, South America, Europe, Asia, Africa, and Oceania. Our Metric Double End Drum Wrench, 27mm x 30mm, Heat Treated and Chrome Plated, Industrial Grade is engineered for professionals who demand reliability and durability in drum handling operations. This double-ended wrench is specifically designed to fit standard metric drum bungs (27mm and 30mm), offering precise torque and a secure grip for opening and closing drums containing chemicals, oils, solvents, or food-grade liquids.
Each wrench is crafted from high-carbon steel, undergoes a rigorous heat treatment process to enhance hardness and wear resistance, and is finished with a durable chrome plating for superior corrosion protection. Whether you work in chemical processing, petroleum refining, or industrial maintenance, this tool ensures long service life and consistent performance under heavy-duty conditions.
Key Features & Benefits
- Double-End Design: Combines 27mm and 30mm sizes in one tool – eliminates the need to carry two separate wrenches. The dual ends are offset for better clearance around drum rims.
- Heat Treated Construction: Full hardening and tempering process increases surface hardness (HRC 38–42) for superior wear resistance and prevents deformation under high torque.
- Chrome Plated Finish: Electroplated chrome layer provides excellent corrosion resistance against moisture, chemicals, and harsh environments. Easy to clean and maintain.
- Industrial Grade Quality: Manufactured to strict tolerances (±0.5mm on working ends) to ensure snug fit on drum bungs without slipping or damaging the fastener.
- Ergonomic Handle: Smooth, rounded edges reduce hand fatigue during repetitive use. The wrench can be used with a cheater bar for additional leverage when needed.
- Versatile Applications: Ideal for open-head and closed-head drums in industries such as chemical, petrochemical, pharmaceutical, food processing, paint, and waste management.

Why Choose Our Drum Wrench?
Our double-end drum wrench is designed with the end-user in mind. The 27mm x 30mm metric sizing covers the two most common drum bung dimensions in the metric system – typically used for 20L to 220L drums. The heat treatment ensures that the wrench maintains its shape even after repeated heavy torquing, reducing the risk of rounding off the nut. Chrome plating not only adds a professional appearance but also facilitates easy cleaning and resistance to most industrial chemicals.
This tool is compatible with standard drum plugs and can be used with both steel and plastic drums. The double-end configuration provides two working options: use the 27mm end for smaller bungs and the 30mm end for larger ones. An offset angle (about 15 degrees) on each end offers better clearance, allowing the wrench to grip the bung without interference from the drum rim.

Frequently Asked Questions (FAQ)
-
Q: Are 27mm and 30mm sizes suitable for all standard drums?
A: These metric sizes are commonly used for drum bungs on 20L, 30L, 50L, 100L, and 200L drums in most regions. However, some drums may use different sizes (e.g., imperial). Please verify your bung size before ordering. -
Q: Is this wrench safe for use on chemical drums containing hazardous materials?
A: Yes. The chrome-plated surface resists corrosion from many chemicals. For extremely corrosive environments, we recommend using stainless steel tools; this wrench is suitable for most normal industrial chemicals. -
Q: Can I use this wrench with a power tool or impact driver?
A: This wrench is designed for manual use. Using with power tools may cause damage or injury. For high-torque applications, use a hand tool with a cheater bar. -
Q: How do I maintain the chrome plating?
A: Simply wipe clean with a dry cloth after use. Avoid prolonged exposure to strong acids or bases. If the plating gets scratched, it will not rust as quickly as uncoated steel, but periodic oiling is recommended. -
Q: Does the heat treatment affect the strength of the wrench?
A: No. Proper heat treatment improves hardness and toughness without making the tool brittle. Our process is carefully controlled to achieve the optimal balance. -
Q: Can I order a custom length or different size ends?
A: Yes, we offer customization services for large orders. Minimum order quantity may apply. Please contact our sales team with your requirements. -
Q: What is the warranty on this drum wrench?
A: We provide a 12-month warranty against manufacturing defects. If you experience any quality issues, we will replace the tool free of charge. -
Q: Is there a risk of slipping or rounding the bung nut?
A: The 6-point hex design provides a snug fit. However, if the bung is worn or damaged, slipping may occur. Ensure the wrench is fully seated before applying force.
