The Open & 12 Point Box Wrench 15° Angle 16 mm (IMPA 610770) is a dual-end combination wrench designed for maximum versatility in tight spaces. The open-end jaw is slim and tapered, allowing quick engagement with fasteners in confined areas, while the 12-point box end provides superior grip and torque transfer, reducing the risk of rounding fasteners. Both ends are the same size (16 mm), making this wrench a practical choice for marine, industrial, and mechanical applications.

Crafted from drop forged alloy steel and heat treated for hardness and toughness, this wrench offers excellent durability and wear resistance. The 15° offset angle on both ends provides better clearance over obstructions and improves hand comfort during use. Ideal for ship engine maintenance, pipeline assembly, steel structure work, and general bolting tasks.
