A Hydraulic Direct Fit Wrench is a compact, high-precision hydraulic torque wrench designed to apply controlled, repeatable torque to hexagonal or low-clearance bolts and nuts. The term “direct fit” refers to its low-profile cassette design, where the hydraulic drive unit directly engages a removable hex cassette that fits tightly over the nut, allowing access to bolts in confined or recessed spaces where standard square-drive wrenches cannot operate. These tools are commonly used in wind turbine assembly, power generation, petrochemical plants, offshore platforms, heavy machinery, and structural steelwork, where accurate, high-torque tightening (up to 70,000 Nm or more) is required.
