Welcome to Cangzhou Dean Safety & Special Tools Co., Ltd. – a trusted manufacturer with over two decades of expertise in producing high-quality safety tools. Our Non-Sparking Double Head Drum Wrench, 350mm, made of premium Beryllium Bronze, is engineered specifically for professionals working in explosive environments where even the smallest spark can lead to catastrophic accidents. This 350mm wrench features two versatile drive ends – 70x70mm and 95x70mm – offering maximum flexibility for opening and tightening drum caps, bung plugs, and other fasteners on industrial drums. By combining superior material science with precision manufacturing, we deliver a tool that not only meets but exceeds the demands of high-risk workplaces. Choose Dean Safety for reliable, non-sparking performance every time.
Our double head drum wrench is crafted from Beryllium Bronze, a copper-based alloy known for its excellent non-sparking properties, high tensile strength, and corrosion resistance. This material is ideal for use in environments with flammable gases, vapors, dusts, or liquids – such as oil refineries, chemical plants, gas stations, paint factories, and mining sites. The 350mm (approx. 13.8 inches) length provides optimal leverage for loosening stubborn drum closures without excessive force, reducing user fatigue and improving safety. The two drive ends are precision-machined to fit standard drum cap sizes: one square opening of 70x70mm (2.76in x 2.76in) and another of 95x70mm (3.74in x 2.76in). This dual configuration allows you to handle both large and small drum caps with a single tool, saving time and effort. Each wrench is individually polished to remove burrs and sharp edges, ensuring a comfortable grip and smooth operation.

Frequently Asked Questions (FAQ)
-
Q: Is this wrench truly non-sparking? How is it tested?
A: Yes, it is manufactured from beryllium bronze alloy which is classified as non-sparking. Our tools undergo routine spark testing in accordance with ASTM F476 and similar standards to ensure they generate no sparks under impact or friction. -
Q: Can this wrench be used in underwater or wet environments?
A: Absolutely. Beryllium bronze offers excellent corrosion resistance, making it suitable for damp or wet conditions. However, rinse with fresh water after exposure to saltwater or chemicals to prolong life. -
Q: What is the difference between 70x70mm and 95x70mm drive ends?
A: The 70x70mm square fits standard smaller drum caps (e.g., tight-head drum plugs), while the 95x70mm square accommodates larger caps used on open-head drums. Both are common sizes in industrial settings. -
Q: Does this wrench come with any certification?
A: We provide material test certificates (MTC) upon request. Certified compliance with ATEX, IECEx, or other standards can be arranged for bulk orders – please inquire for specific requirements. -
Q: Is the 350mm length comfortable for people with smaller hands?
A: The 350mm length is designed to provide leverage without being excessively large. It is manageable for most adult users; if you need a shorter version, we offer custom lengths (minimum order quantity may apply). -
Q: Can I order this wrench with my company logo engraved?
A: Yes, we offer laser engraving or stamping of logos, part numbers, and safety warnings. Minimum order quantities for customization are reasonable – contact our sales team for details. -
Q: How should I store the wrench to maintain its properties?
A: Store in a dry, clean environment. Avoid contact with strong acids or alkalis for prolonged periods. Clean with a soft cloth and apply a light rust preventive oil if stored for extended time (though beryllium bronze rarely rusts). -
Q: What is the typical lead time for international shipping?
A: For standard quantities (1-200 pcs), lead time is 10-15 days after order confirmation. Larger orders or custom products may require 20-30 days. We ship via air or sea from Tianjin/Shanghai/Ningbo port.
