The Micrometer Adjustable SDR Series - Square Drive Ratchet- Knurl Grip

Have micrometer adjustable click wrenches with the neoprene grip and want to convert to the Knurl Grip handle? You can do it yourself and order the parts by going to the Knurl Grip Conversion Kit page.

Applications

Micrometer Adjustable Fixed Square Drive torque wrenches are ideal for any application where:

  • The fastener or fitting can be engaged with a socket.
  • The operator has to frequently change torque values.
  • High rotation or limited access requires ratcheting to achieve torque level.
  • Repeatability and reliability are important.
  • Reducing side load during torque application or testing is imperative. 
  • The ability to quickly select torque value and lock it is needed.
  • Operational simplicity is needed.
  • High durability is important.

Small quantity assembly operations, as well as maintenance and repair functions, find the SDR line of wrenches to fit very well with their needs.

Features and Characteristics 

  • Adjust torque value by rotating the grip.  
  • Grip lock makes locking in torque value fast, easy, and secure.
  • When in a hurry, our tools change from one end of the scale to the other with the fewest number of turns. 
    Adjusting the torque value on a micrometer adjustable torque wrench

  • Ball bearing rock-over assembly assures smooth operation enhances repeatability and increases wrench service life.
  • The accuracy of +/- 4% of Indicated Value from 20% to 100% of rated capacity.
  • Meets or exceeds requirements of ASME B107.300-2010 and ISO 6789.
  • Error Proofing By Guidance design provides a strong audible and tactile impulse when the set torque is achieved.
  • Error Proofing By Design flattened case provides the mechanism with superior support resulting in a wrench that is easier to calibrate and one that holds calibration longer. 
  • The flattened case prevents side loading during torque application or testing/calibration. 
  • Knurled grip offers an ergonomic grip that remains comfortable over long periods of use.
  • Changing values with the fewest number of turns save time and energy.
  • Ratchet is built for durability.
  • Ratchet replacement is fast and easy when needed.
  • All tools up to 250 ft-lb capacity come with a rugged, custom molded plastic case.
  • Includes FREE tabulated calibration certificate from our ISO 17025 certified calibration laboratory.

 

Tips From Torque Man

Many people believe that a micrometer adjustable wrench should be set to zero or no load on the spring when work is completed. Many torque wrench mechanisms are held in place by the spring tension. Unloading the spring allows the internal parts to move and can easily cause the wrench to quickly go out of calibration.

You won't find out until the wrench goes in for its annual calibration.

Sturtevant Richmont micrometer adjustable wrenches are engineered with Error Proofing By Design. SR wrenches need only to be taken down to 20% of capacity. Taking the torque setting down to zero or below with our wrenches is not needed. And, it is not possible.  

Sturtevant Richmont micrometer adjustable torque wrenches are designed for accuracy, reliability, and durability. To achieve those factors the internal design is dramatically different than other adjustable wrenches. 

Accurate. Reliable. Durable. It is all part of our Error Proofing By Design.
