Welcome to Cangzhou Dean Safety & Special Tools Co., Ltd – a trusted manufacturer since 2001 with an annual export value exceeding US$100 Million. Our 15mm-19mm Double Ended Box Wrench Heavy Duty 12-Point is engineered for demanding industrial maintenance environments. This professional-grade wrench combines precision forging with a robust 12-point design to deliver superior torque transfer and fastener control, ensuring that your maintenance tasks are completed efficiently and safely.
With decades of experience serving global markets including North America, South America, Europe, and Asia, we understand the rigorous requirements of industrial professionals. Each wrench undergoes strict quality checks to guarantee reliability under heavy workloads. The double-ended configuration saves time by providing two common sizes in one tool, while the heavy-duty construction withstands repeated high-torque applications without deformation.
Key Features & Technical Specifications
Dual Size Design: 15mm on one end and 19mm on the other – covers two frequently used fastener sizes for industrial machinery and equipment.
12-Point Configuration: Provides excellent gripping on hex bolts and nuts, allowing for finer rotation increments and reducing the risk of rounding.
Heavy Duty Construction: Made from drop-forged alloy steel and heat-treated for maximum strength and durability. The black oxide finish resists corrosion and improves surface hardness.
Ergonomic Profile: The box end design fully encircles the fastener, distributing force evenly to prevent slippage and damage. Smooth edges ensure comfortable handling even during extended use.
Industrial Maintenance Focus: Ideal for assembly lines, repair shops, plant maintenance, and other heavy-duty applications where reliability is critical.

Corrosion Resistance: Black oxide finish offers protection against moisture and chemicals, extending tool life in harsh industrial environments.
Better Access: The slim box end profile allows use in tight spaces where a larger wrench might not fit.
Safety: The full-circle engagement reduces the risk of slipping, protecting both the operator and the fastener.
