Direct Reading Flat Beam Memory Wrench

The SR line of 'Flat Beam' torque wrenches is the direct descendant of those produced by P. A. Sturtevant in the 1930's, and is still among the most accurate and durable of all torque wrenches on the market! The four most important requirements of a torque wrench – accuracy, reliability, durability, low ownership cost – are combined into these exceptional tools. Accuracy is literally ground into the wrench. The service life of these tools is frequently measured in decades!

 

The special alloy steel beam is ground to a rate of deflection with the use of dead weights, rather than a dimensional tolerance. This process is time consuming and very labor intensive, but the result is a tool that remains accurate as long as the beam is intact and the pointer is on zero under no-load condition.

 

The flat shape of the beam insures the wrench remains at a right angle to the fastener, reducing or eliminating side-loading error. This unique taper-grinding distributes stress evenly along the entire length of the beam, extending tool life indefinitely. With a minimum of moving parts, these tools are virtually repair and maintenance free.

 

These torque wrenches are ideal for aircraft assembly and maintenance operations, fastener testing (in-process/final/receivinging inspection) for prevailing torque nuts, and assembly compliance testing for products with rotating components. For these and similar operations, Flat Beam torque wrenches are often the best tool for the job.

 

Key Features

  • Incredibly durable design, with a service life frequently measured in decades!
  • Very low cost of ownership - exceptional accuracy retention permits extended calibration intervals, and they are virtually maintenance and repair free!
  • Ideal for prevailing-torque and destructive testing applications!
  • Low mass/low inertia design of pointers helps eliminate reading distortion.
  • Memory feature consists of fingers that follow a track in the scale and remain in place to indicate the maximum torque achieved.
  • Pivoted handles concentrate the applied load (force) at a precise point on the lever to assure torque accuracy.
  • The SR flat beam torque wrenches meet or exceed all requirements of ASME B107.14M and ISO 6789.
  • Accuracy of SR flat beams is ± 2% of Indicated Value from 20% to 100% of wrench capacity in both directions.
  • FREE included with each wrench!
