Snap-on Reaction Arm

The use of torque multipliers are essential when high torque is needed in heavy duty applications including power generation, oil and natural gas, railroad and other critical industries.


Snap-on Reaction ArmA key component of successful torque multiplier application are reaction arms. Snap-on Industrial offers a wide range of reaction arms to integrate with manual, cordless and pneumatic torque multipliers. Reaction arms improve torque access for applications involving:

  • Heavy duty fleet maintenance
  • Structural bolting
  • Flange bolting
  • Wind turbine erection / maintenance
  • General maintenance

Reaction arms work by directing all torque forces back to the adjacent fasteners or structure, eliminating unintentional rotation of the torque multiplier during operation. Popular styles of reaction arms include:

Straight reaction (SR18291); 11.8” length; light-weight reaction; reduces tool weight
Straight reaction with peg (SRP18298); 11.8” length, 3 offset inches; light-weight reaction; reduces tool weight
Double-sided reaction fixture (MTMC18293); 7.9” length; light-weight reaction; reduces tool weight
Short reaction foot (SRF18241); 2.55” length, 3 offset inches; light-weight reaction; reduces tool weight
Reaction adaptor (RA18290); light-weight reaction; reduces tool weight

Custom-built reaction arms and sets can also be designed for your exact torque application.b2b.snapon.com/reactionarms.
