Torque Multipliers

Torque multipliers are mechanical tools that increase the applied torque from a wrench or ratchet, enabling controlled, repeatable tightening and loosening on high-torque fasteners. They are used when required torque exceeds the capacity of standard torque wrenches, or when restricted access makes long lever arms impractical while still demanding accurate torque application.

In this collection you’ll find torque multiplier solutions from Insize, available with different gear ratios and torque ranges to deliver consistent output with minimal loss. Options include various input/output square drives, compatibility with torque wrenches for precise setting, and practical accessories such as reaction arms to safely manage counter-torque and maintain stability during operation.

Torque multipliers are widely used by maintenance technicians, mechanical engineers, and QC teams in industrial plants, energy and utilities, marine service, and heavy fabrication—especially for flange bolting, large-diameter fasteners, and critical assemblies where traceable, repeatable torque is essential.
