Product Description
This striking open-end wrench is forged from high-quality alloy steel with a thick, heavy-duty structure designed for large fasteners and high-torque maintenance work. The reinforced striking end can be hit with a hammer or sledgehammer to deliver additional impact force and torque, helping loosen or tighten large, rusted, seized, or difficult fasteners.
The wrench features a phosphated surface finish for good rust resistance, corrosion protection, and wear durability. Its open jaw allows quick side access to large hex nuts, bolts, flange fasteners, and valve connections. It is especially suitable for pipelines, industrial valves, construction machinery, steel structures, shipbuilding, mining, and energy equipment maintenance.
Available from 22mm to 120mm, this heavy-duty striking wrench is manufactured to DIN standard requirements and is an essential hand tool for industrial installation, maintenance, and repair work.
