Need the instruction set for your BLT, bi-directional, preset click wrench with interchangeable heads? Scroll down to the bottom of the page and the instruction set is available for download there. 

Please note that this is a bi-directional preset torque wrench, meaning that this wrench will apply and measure torque in both the clockwise and counter-clockwise direction. 

When the wrench clicks, the designated amount of torque has been applied. Stop pulling. Continuing to pull after the wrench clicks can increase the applied torque to a value that exceeds the engineering specification.

Applications  

BLT Bidirectional Click Wrench from Sturtevant RichmontBi-directional Preset Interchangeable Head torque wrenches are ideal for any application where:

  • The fastener or fitting to be tightened cannot readily be engaged with a socket.
  • Repeatability is crucial to accurate assembly.
  • It is advisable to eliminate the possibility of having the operator set the wrong torque on the tool.
  • Very high durability is important.

These needs are common in assembly and standardized field maintenance operations, and the BLT-Series tools are superb for these types of applications. 

Features and Characteristics

  • SR Dovetail Head connects to over 100 SR Interchangeable Heads. All of our interchangeable heads fit on all of our dovetail wrenches, meaning you don’t have to buy multiple wrenches and heads in the same torque range to cover all fastener sizes.
  • Error Proofing By Design: the SR Dovetail transmits the load at a right angle from the wrench to the head, providing exceptional strength and rigidity of the connection.
  • A pin lock on the dovetail assures positive head connection, yet permits head changeover in seconds.  <
  • BLT-Series torque wrenches have CW +/- 4% Indicated Value Accuracy and CCW +/- 6% Indicated Value Accuracy from 20% to 100% of capacity, meeting or exceeding the requirements of ASME B107.300-2010 and ISO 6789.
  • If we preset the tool to your requested torque value, we include a Certificate of Calibration from our ISO 17025 Accredited Lab. 
  • Error Proofing By Behavior Modification: excellent tactile and audible pulse when the preset torque is achieved.
  • Error Proofing By Design: the flattened case prevents side-loading and ensures greater accuracy and durability. 
  • Comfortable cushion grip plus light-weight for excellent ergonomics.
  • The torque is preset and locked in with a special CART tool.
  • Torque can be set using any unit of measurement.
  • Can be ordered preset from the factory or you can set the torque with your own torque tester.
  • All of our tools provide torque measurements in the clockwise direction. The BLT preset click wrench measures torque in both clockwise and counterclockwise directions.
