The Torque Control Wrenches in our STC Series are Designed for Precise Calibration and Versatile Applications

Our most versatile torque control wrench, the STC Series can be used for a number of applications. It can be used for the work of snug tightening your bolts; or it can be used as a calibrated wrench; and DTI installation jobs. You can even use it for turn of nut applications. They use standard impact sockets and there are torque multipliers designed for these tools that will increase the torque of the wrench up to 21x its usual capacity.

With an STC Series Torque Control Wrench You Get:

  • Powerful, controllable torque
  • Torque control function works in both directions
  • Non-impact/constant speed
  • One-sided installation
  • Quiet, smooth operation
  • Easy transition from impact tools because these use standard impact sockets
  • Easy handling

 

For snug tightening or calibrated wrench installations, simply set the torque control dial to the torque necessary to “snug” tighten or fully pretension the bolt assembly. For DTIs, you set the torque to the amount necessary to compress the DTI washers to the required gap, then the tool will stall when it reaches the preset torque. For turn of nut, mark the socket for the specified angle of rotation and rotate the socket until it satisfies the specified amount of turn.

We have a complete stock of spare parts and accessories for all STC Wrench models that are available for same day shipment.

  • STC-50AE/STC-50TE When it comes to brute power, our STC 50 is the largest in the class. It has an astounding adjustable torque range of 1500 – 3700  ft. lb

Accessories for the STC Series includes Torque Multipliers

All STC wrenches have torque multipliers available to increase their capacity. Torque Multipliers allow a single STC Series wrench to install a full range of bolt sizes and grades.

Torque multipliers are easily attached to the STC wrenches. Just slide the multiplier over the square drive on the wrench.

The addition of a torque multiplier can increase the maximum torque output of the STC Series wrenches by up to 450%.
