Open & 12 Point Box Wrench 54 mm – 15° Offset

This 54 mm open and 12 point box wrench is a versatile combination tool designed for heavy-duty marine and industrial applications. The 15° offset angle on both ends provides improved clearance and knuckle protection when working in tight spaces. Each end features the same 54 mm opening, allowing you to use either the open end for quick positioning or the box end for maximum torque.

Crafted from drop forged alloy steel and fully heat treated, this wrench delivers exceptional hardness, toughness, and wear resistance. The open end has a slim profile and tapered jaw for easy access to fasteners in confined areas, while the 12 point box end offers superior grip and reduces the risk of rounding bolt heads. At 635 mm overall length, it provides ample leverage for loosening or tightening large fasteners commonly found in marine engines, piping systems, and structural assemblies.
