55 mm 12-Point Striking Wrench

This 55 mm box wrench is built for heavy-duty fastening where impact force is required. The 12-point drive engages bolts from multiple angles for a secure grip. A 45° offset head clears obstructions in tight machinery. It suits maintenance technicians and industrial assemblers who need reliable striking tools.

Forged Steel Build for Impact Use

Forged from premium tool steel, the wrench withstands repeated hammer blows on its large striking block. The black oxide finish resists corrosion in workshop environments. Precision broaching ensures a tight fit on 55 mm fasteners, reducing rounding risk. The design frees up access where straight-handled wrenches cannot reach.

Hand Tool With No Power Needs

As a manual striking wrench, it draws no power and produces no operating noise beyond the hammer impact. Thermals are not a factor during normal use. The robust block maximises surface contact for safety when transferring force. California Proposition 65 warnings apply for chemical exposure.
