Torque Multipliers

BELKNAP’S GEARED HEAD TORQUE MULTIPLIERS are incomparable to any other tool. The multiplication is achieved through a planetary gear train at a ratio depending on the
model. The precision gear train is totally enclosed. 

Torque MultiplierThis torque multiplier is a silent partner to all operators. It provides ample power by multiplying the amount of torque applied with your torque wrench. Basically, you can tighten high torque fasteners by only applying a few foot pounds. Relatively small, torque multipliers may be used with practically all accessory tooling and provides ample torque power in limited work areas.

Use of a torque multiplier will vastly improve the overall efficiency of the operator. It is also an easier and safer way to achieve a high torque requirement.


  • Alloy forged head.

  • General all-purpose tool.
  • Provides ample torquing power.
